Merge branch 'feature/init-name-resolution'

The previous fix used split('.').next() to get the meta stem from the
snapshot path, which only takes the first dot-segment. This broke names
containing dots (e.g. "Name.new" → "Name.new.luau" would produce
"Name.meta.json" instead of "Name.new.meta.json").

Strip the full middleware extension (e.g. ".server.luau", ".txt") from
the snapshot path filename instead. This correctly handles all cases:
  Name.new.luau      → Name.new  → Name.new.meta.json
  _Init.server.luau  → _Init     → _Init.meta.json
  Name.new.txt       → Name.new  → Name.new.meta.json

 You'll want these tools to work on Rojo:

 * Latest stable [Rojo](https://github.com/rojo-rbx/rojo)
-* [Foreman](https://github.com/Roblox/foreman)

+* [Luau Language Server](https://github.com/JohnnyMorganz/luau-lsp) (Only needed if working on the Studio plugin.)

+When working on the Studio plugin, we recommend using this command to automatically rebuild the plugin when you save a change:
+
+*(Make sure you've enabled the Studio setting to reload plugins on file change!)*
+
+```bash
+bash scripts/watch-build-plugin.sh

 ## Documentation
 Documentation impacts way more people than the individual lines of code we write.
 
-If you find any problems in documentation, including typos, bad grammar, misleading phrasing, or missing content, feel free to file issues and pull requests to fix them.

 ## Bug Reports and Feature Requests
 Most of the tools around Rojo try to be clear when an issue is a bug. Even if they aren't, sometimes things don't work quite right.
