Rename Roots type to Root (#2480)
This was suggested by @jonaprieto in
https://github.com/anoma/juvix/pull/2458#discussion_r1368476371 - but we
deferred it until the Package file PR sequence was merged.

Refactor EntryPoint, Package, Pipeline, Root packages (#2458)
Depends on:
*  https://github.com/anoma/juvix/pull/2451

This PR is part of a series implementing:
* https://github.com/anoma/juvix/issues/2336

In attempt to make the main PR:
* https://github.com/anoma/juvix/pull/2434
easier to review.

Changes in this PR refactor EntryPoint, Package, Pipeline, Root,
splitting out the types into Base modules so that they can be imported
and used in subsequent PRs with fewer dependencies to avoid package
cycles.

Report termination errors after typechecking (#2318)
- Closes #2293.
- Closes #2319 

I've added an effect for termination. It keeps track of which functions
failed the termination checker, which is run just after translating to
Internal. During typechecking, non-terminating functions are not
normalized. After typechecking, if there is at least one function which
failed the termination checker, an error is reported.
Additionally, we now properly check for termination of functions defined
in a let expression in the repl.

Add main field to juvix.yaml (#2120)
- Closes #2067

This pr adds the field `main` to `juvix.yaml`. This field is optional
and should contain a path to a juvix file that is meant to be used for
the `compile` (and `dev compile`) command when no file is given as an
argument in the CLI. This makes it possible to simply run `juvix
compile` if the `main` is specified in the `jvuix.yaml`.

I have updated the `juvix.yaml` of the milestone examples.

Make format command's filepath optional (#2028)
# Description

No the filepath in the `juvix forma` command is n=made optional.
However, in that case, the `--stdin` command is required.

### Implementation details

~For now, as a quick solution, I have introduce the "fake" path that is
used for `fomat` command with stdin option.~
I needed to do a couple of big changes:
* `format` command FILE is now optional, howvere, I check that in case
of `Nothing` `--stdin` option should be present, otherwise it will fail
 * `entryPointModulePaths` is now `[]` instead of `NonEmpty`
* `ScopeEff` now has `ScopeStdin` constructor as well, which would take
the input from stdin instead of having path passed around
* `RunPipelineNoFileEither` is added to the `App` with the bunch of
`*Stdin` functions that doesn't require filepath argument to be passed

Fixes #2008

Support more paths (#2000)
- Closes #1993 

This pr makes it possible to use `~`, `..` and environment variables in
the `juvix.yaml` and all flags / input of the cli.

In the CLI, the shell will be responsible for replacing environment
variables with their value, so the usual syntax can be used. For the
`dependencies` field, I have implemented a parser that has some
restrictions:
1. Environment variables are given with the makefile-like syntax
`$(VAR)`
2. The three characters `$` `(` `)` are reserved for the environment
variables syntax.
    They cannot be part of the path.
3. `~` is reserved for `$(HOME)`. I.e. the prepath `~~` will expand to
`$HOME$HOME`.
4. Nested environment variables are not allowed.

Thanks @paulcadman for the feedback. I think we are ready to merge this
nightmarish pr 👻

Fix REPL state to include enough information to rerun the pipeline (#1911)
Previously we were:
* discarding the types table 
* discarding the name ids state
after processing an expression in the REPL.

For example evaluating:
```
let even : _; odd : _; odd zero := false; odd (suc n) := not (even n); even zero := true; even (suc n) := not (odd n) in even 10
```
would loop in the REPL.

We noticed that the `n` in `suc n` was being given type `Type` instead
of `Nat`. This was because the name id given to n was incorrect, the
REPL started using name ids from 0 again.

We fixed this issue by storing information, including the types table
and name ids state in the Artifacts data structure that is returned when
we run the pipeline for the first time. This information is then used
when we call functions to compile / type check REPL expressions.

Add juvix format command (#1886)
This PR adds `juvix format` that can be used to format either a single
Juvix file or all files in a Juvix project.

## Usage

```
$ juvix format --help
Usage: juvix format JUVIX_FILE_OR_PROJECT [--check] [--in-place]

  Format a Juvix file or Juvix project

  When the command is run with an unformatted file it prints the reformatted source to standard output.
  When the command is run with a project directory it prints a list of unformatted files in the project.

Available options:
  JUVIX_FILE_OR_PROJECT    Path to a .juvix file or to a directory containing a
                           Juvix project.
  --check                  Do not print reformatted sources or unformatted file
                           paths to standard output.
  --in-place               Do not print reformatted sources to standard output.
                           Overwrite the target's contents with the formatted
                           version if the formatted version differs from the
                           original content.
  -h,--help                Show this help text
```

## Location of main implementation

The implementation is split into two components:
* The src API: `format` and `formatProject`
73952ba15c/src/Juvix/Formatter.hs
* The CLI interface:  

73952ba15c/app/Commands/Format.hs

## in-place uses polysemy Resource effect

The `--in-place` option makes a backup of the target file and restores
it if there's an error during processing to avoid data loss. The
implementation of this uses the polysemy [Resource
effect](https://hackage.haskell.org/package/polysemy-1.9.0.0/docs/Polysemy-Resource.html).
The recommended way to interpret the resource effect is to use
`resourceToIOFinal` which makes it necessary to change the effects
interpretation in main to use `Final IO`:
73952ba15c/app/Main.hs (L15)

## Format input is `FilePath`

The format options uses `FilePath` instead of `AppFile f` for the input
file/directory used by other commands. This is because we cannot
determine if the input string is a file or directory in the CLI parser
(we require IO). I discussed some ideas with @janmasrovira on how to
improve this in a way that would also solve other issues with CLI input
file/parsing but I want to defer this to a separate PR as this one is
already quite large.

One consequence of Format using `FilePath` as the input option is that
the code that changes the working directory to the root of the project
containing the CLI input file is changed to work with `FilePath`:


f715ef6a53/app/TopCommand/Options.hs (L33)

## New dependencies

This PR adds new dependencies on `temporary` and `polysemy-zoo`.

`temporary` is used for `emptySystemTempFile` in the implementation of
the TempFile interpreter for IO:


73952ba15c/src/Juvix/Data/Effect/Files/IO.hs (L49)

`polysemy-zoo` is used for the `Fresh` effect and `absorbMonadThrow` in
the implementation of the pure TempFile interpreter:

73952ba15c/src/Juvix/Data/Effect/Files/Pure.hs (L91)

NB: The pure TempFile interpreter is not used, but it seemed a good idea
to include it while it's fresh in my mind.

* Closes https://github.com/anoma/juvix/issues/1777

Pattern matching compilation (#1874)
This implements a basic version of the algorithm from: Luc Maranget,
[Compiling pattern matching to good decision
trees](http://moscova.inria.fr/~maranget/papers/ml05e-maranget.pdf). No
heuristics are used - the first column is always chosen.

* Closes #1225 
* Closes #1926 
* Adds a global `--no-coverage` option which turns off coverage checking
in favour of generating runtime failures
* Changes the representation of Match patterns in JuvixCore to achieve a
more streamlined implementation
* Adds options to the Core pipeline

Update CI to install Smoke, Github actions, and Makefile fixes (#1735)
This PR adds some maintenance at different levels to the CI config, the
Make file, and formatting.

- Most of the actions used by the CI related to haskell, ormolu, hlint
and pre-commit have been updated because Github requires NodeJS 16. This
change removes all the old warnings related to nodeJs.
In the case of ormolu, the new version makes us format some files that
were not formatted before, similarly with hlint.
- The CI has been updated to use the latest version of the Smoke testing
framework, which introduced installation of the dependencies for Linux
(libicu66) and macOS (icu4c) in the CI. In the case of macOS, the CI
uses a binary for smoke. For Linux, we use stack to build smoke from the
source. The source here is in a fork of [the official Smoke
repo](https://github.com/SamirTalwar/smoke). Such includes some
features/changes that are not yet in the official repo.

- The Makefile runs the ormolu and hlint targets using as a path for the
binaries the environment variables ORMOLU and HLINT. Thus, export those
variables in your environment before running `make check,` `make format`
or `make hlint`. Otherwise, the Makefile will use the binaries provided
by `stack`.

Support go to definition for the standard library (#1592)
* Remove ParserParams

ParserParams is only used to record the root of the project, which is
used to prefix source file paths. However source file paths are always
absolute so this is not required.

* Add GetAbsPath to Files effect

The Files effect is not responsible for resolving a relative module
path into an absolute path on disk. This will allow us to resolve
relative module paths to alternative paths, for example to point to the
standard library on disk.

* Files effect getAbsPath returns paths within the registered standard
library

This means that the standard library can exist on disk at a different
location to the Juvix project.

A command line flag --stdlib-path can be specified to point to a
standard library, otherwise the embedded standard library is written to
disk at $PROJ_DIR/.juvix-build/stdlib and this is used instead.

* Recreate stdlib dir only when juvix version changes

* Add UpdateStdlib to the Files effect

* Add comment for stdlibOrFile

* Remove spurious import
