docs: route CLAUDE.md's canonical-state list to the CI/release SSOT

Sessions start from CLAUDE.md's reading list; the Gitea pipeline, the
self-hosted runners, the release/pointer layout, and the Lane=Timing rule now
have a one-line entry there so the next session finds docs/ci-and-releases.md
before touching CI.

CLAUDE.md

@@ -765,6 +765,7 @@ Documentation entry point: [`docs/README.md`](docs/README.md).
 For canonical state, read in this order:
 - [`docs/plans/2026-07-29-network-transport-campaign.md`](docs/plans/2026-07-29-network-transport-campaign.md) — Campaign N, the retail reliable-transport port — **CLOSED 2026-07-29, user-accepted** (#260 closed; a real wire loss recovered live during the acceptance session). Still the SSOT for the transport mechanism, the ACE constraint table, and the landmine list — read it (or `claude-memory/project_network_transport_digest.md`) before touching anything under `src/AcDream.Core.Net/`.
 - [`docs/plans/2026-07-27-vulkan-campaign.md`](docs/plans/2026-07-27-vulkan-campaign.md) — Campaign V, OpenGL → Vulkan — **CLOSED 2026-07-29**; the completed record of the RHI contract, V0–V11 slices, and the GL deletion. Historical reference for `src/AcDream.App/Rendering/`.
+- [`docs/ci-and-releases.md`](docs/ci-and-releases.md) — **the Gitea CI/release SSOT (2026-08-19)**: every push to main gates on two self-hosted runners (RARE-win / eriktestLinux) and publishes a Gitea Release the launcher installs from; payloads are release attachments, the `latest` release is the launcher's pointer, old releases are pruned to 5. Load-sensitive tests live in `Lane=Timing` (see `docs/release-gate.md`) — do NOT chase them individually.
 - [`docs/plans/2026-05-12-milestones.md`](docs/plans/2026-05-12-milestones.md) — milestone targets + freeze list per milestone
 - [`docs/plans/2026-04-11-roadmap.md`](docs/plans/2026-04-11-roadmap.md) — what's shipped, what's in flight, what's next
 - [`docs/ISSUES.md`](docs/ISSUES.md) — open + recently closed bugs (tactical)
