fix(ci): clear knip unused-exports failures on dev (#119)

The `npm run knip` step in the TypeScript/Lint/Tests workflow has been
red on every push to dev since 55091f0. Two distinct sources:

- `MessageLoadResult` in `useChatStore.ts` was exported but only consumed
  in the same file (as the type of an internal store field). Demote to a
  file-private interface.
- `KnownBridgeKey` and `DataBridgeProbeResult` in
  `theia/dataBridgeReader.ts` were exported (and re-exported through
  `theia/index.ts`) for use as type annotations at call sites that
  actually rely on TypeScript inference. The exports were never read.
  Demote to file-private and drop the barrel re-exports.

Also drop the redundant `esbuild.js` entry from `knip.json` — knip
auto-detects build configs and was flagging it as a configuration hint.

After this commit, `npm run knip` exits 0 locally with no warnings.
