Add L15 complete Worker routing for all v0.1 XRPC endpoints
Wire 12 missing HTTP route handlers into src/worker.ts:
- Static: GET /.well-known/welcome.md, GET /tos
- Public repo reads: getRecord, listRecords, describeRepo
- Authenticated writes: createRecord, putRecord, deleteRecord, applyWrites
- Public sync reads: getRepo (CAR), getLatestCommit, getRepoStatus
Add rpcPutRecord (create-or-update) and applyWrites#update support
to src/account-do.ts. Add ROOKERY_RELAY_HOSTS to Env in src/types.ts.
Add fire-and-forget requestCrawl relay announcement on first request.
