chore(dead-exports): purge 222 dead exports, add CI guard (CL-6797)

Triage ts-prune report; allowlist 218 deliberate-public-surface exports in
scripts/dead-export-allowlist.txt with reasons (CL-6815 lanes preserved).
Delete 222 consumer-less exports including 4 fully-dead barrel files
(net -566 lines across 51 files). Wire scripts/check-dead-exports.ts into
package.json check script and CI dead-exports job.

 `bun run check` is the single pre-PR gate: it runs `lint`, `typecheck`,
-`build`, and `check:projects-dir-guard` — which runs the `test` suite under
+`check:dead-exports`, `build`, and `check:projects-dir-guard` — which runs the `test` suite under
 the projects-dir sandbox guard — in that order, matching CI.
 
 Run the full suite before declaring any task complete. Do not substitute individual targets. If a failure is pre-existing and unrelated to your change, say so explicitly.
