release(v4.8.1): SHADE_DISABLE_RATE_LIMIT env var for single-tenant deploys

Plumbing fix only — both createPrekeyRoutes and createInboxRoutes
already accepted disableRateLimit; standalone.ts just didn't read
the env. Now SHADE_DISABLE_RATE_LIMIT=1 turns off IP rate-limits on
every prekey + inbox route, with a WARN log on startup so operators
see it.

Single-tenant deployments only — multi-tenant relays must leave it
unset. Documented in docs/DEPLOYMENT.md.

Reported by Prism: ~6 pair attempts/hour from a single dev IP +
the sidecar's register call tripped the 5/hour REGISTER_LIMIT every
dev iteration.

+## [4.8.1] — 2026-05-08 — `SHADE_DISABLE_RATE_LIMIT` env var for single-tenant deploys
+
+The standalone server's `routes.ts` and `inbox-server`'s
+`createInboxRoutes` already accepted a `disableRateLimit?: boolean`
+option, but the standalone entry just didn't read it from environment.
+Self-hosted single-tenant deploys (Prism's relay is a typical case —
+only Prism PC clients + their paired browsers) tripped the
+`REGISTER_LIMIT` (5/hour per IP) every dev iteration: ~6 pair attempts
+in an hour from the same IP plus the sidecar's register call killed
+the dev loop until the bucket refilled (~1 token per 12 minutes).
+
+Reported by Prism. Two-line plumbing fix: `standalone.ts` now reads
+`SHADE_DISABLE_RATE_LIMIT=1` and forwards `disableRateLimit` to both
+`createPrekeyRoutes` and `createInboxRoutes`.
+
+### Added
+
+#### `@shade/server`
+- `SHADE_DISABLE_RATE_LIMIT=1` env var disables IP rate-limits on every
+  prekey + inbox route in `standalone.ts`. Logged as a `WARN` on startup
+  (`SHADE_DISABLE_RATE_LIMIT=1 — IP rate limits OFF on prekey + inbox
+  routes`) so operators see it in stderr/log aggregation.
+- **Single-tenant deployments only** — multi-tenant relays must leave
+  this unset. The rate-limit defends multi-tenant relays against abuse;
+  flipping it off is appropriate for self-hosted single-team setups
+  where every caller is a known client. Documented in
+  [`docs/DEPLOYMENT.md`](./docs/DEPLOYMENT.md) under "Environment variable
+  reference".
+
+### Tests
+- `packages/shade-server/tests/rate-limit.test.ts` — the existing
+  "register endpoint rate-limits per IP" test verifies the default-on
+  path; a new sister test exercises
+  `createPrekeyServer({ disableRateLimit: true })` and confirms 12
+  consecutive register calls from the same IP all return 200 (no 429).
+  The env-var → option conversion in `standalone.ts` is a one-liner
+  verified by inspection.
+
+### Migration
+
+None. Default is unchanged (rate limits stay ON). Self-hosted
+single-tenant operators add `SHADE_DISABLE_RATE_LIMIT=1` to their
+deployment env to flip it off.
+
 ## [4.8.0] — 2026-05-08 — Sender-fingerprint attribution + `Inbox.start()` race fix
 
 Two unblocking changes for first-contact flows. First, the relay now
