Add multi-root bundle support across the toolchain:
- `compile`: Accept multiple definition names via `-x NAME` (repeatable or
comma-separated). Exports all requested definitions as named roots in a
single bundle. Defaults to "main" when no names are given.
- `export`: Accept comma-separated hashes in the positional argument and
multiple `-n`/`names` flags. Exports all resolved roots in one bundle.
- Server: Add `GET /bundle/roots?n=...&h=...` endpoint that resolves
multiple stored-term names and/or raw Merkle hashes, returning a single
bundle containing all of them as roots.
- Wire: Export `defaultExportNames` helper for generating default export
names when none are supplied.
- Drop `cereal` dependency from `tricu.cabal` (no longer used).
Introduces a read-only HTTP server (WAI/Warp) backed by the content
store, exposing three bundle-export endpoints:
- GET /bundle/name/:name — export by stored term name
- GET /bundle/hash/:hash — export by full Merkle hash
- GET /terms — plain-text listing (debug)
Also adds `tricu server` (aka `--serve`) CLI mode, move `resolveExportTarget` /
`namesForHash` / `looksLikeHash` out of `Main.hs` into `ContentStore.hs`,
and cleans up unused exports and imports across `FileEval.hs` and `Wire.hs`.
Adds support for REPL namespacing, primarily to avoid `main` collisions.
Also adds a library function for an ergonomic pattern matching function
that I've been noodling on. I might explore ways to make list syntax
less annoying specifically for pattern matching like this.
Don't require/allow naming a module, instead require that the importer
names it. Allow importing into the local scope with the name !Local.
Simplify namespacing logic. Updates all tests to reflect these changes.
To encourage organizing code in a way that helps in understanding, I
have implemented the common idiom of requiring a `main` function. In
tricu and other functional languages, it is usually placed near the top
of the module. The evaluator gracefully handles the situation of passing
multiple files where the intermediary "library" files do not have main functions.
