feat: HTTP server for exporting Arborix bundles

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`.

+I have fully embraced the slopmachine (LLM-assisted development) for this project. Nothing is stable or sacred. We will discover sanity at the end of the journey but we won't strive for it until then.

 Tree Calculus was discovered by [Barry Jay](https://github.com/barry-jay-personal/blog). The addition of Triage rules were suggested by [Johannes Bader](https://johannes-bader.com/). Johannes is also the creator of [treecalcul.us](https://treecalcul.us) which has a great intuitive code playground using his language LambAda.

-This really is a repo for experimentation so I'm not doing anything sane with the versioning for now. If I decide to stabilize the project we'll start anew at 2.0.
