docs(claude): update build state section to v0.4.0 reality

The "Current build state" section described a scaffolded, intentionally
RED repo (ErrNotImplemented, go 1.23, unverified confirm items). All
stale: build is v0.4.0 green, go 1.26.1 (go.mod), Stage 1 multi-user
with RLS shipped (ADR-012, migrations 001-006). Rewrote to describe the
actual adapters, cmd subcommands (incl. serve), and how to build/run.
Replaced the "confirm" list with the resolved homelab facts (LiteLLM
koala:30401, model-as-config) now pinned in homelab-integration.md.

 ## Current build state (start here for the first task)
 
-The repo is **scaffolded and intentionally RED**:
+The repo is **green and shipping** — last tag `v0.4.0`. `task check` passes (fmt, vet, lint,
+`go test -p 1 ./...`). Go is `1.26.1` (see `go.mod`).
 
-- Clean Architecture skeleton exists: `internal/domain` (entities), `internal/ports`
-  (interfaces), `internal/usecase` (engine), `cmd/tapir` (entrypoint stub),
-  `internal/adapters` (empty — concrete adapters go here).
-- `usecase.Engine.ProcessNewVideo` returns `ErrNotImplemented`.
-- `test/acceptance/summarize_new_video_test.go` translates the first two Gherkin scenarios and
-  **fails** against the stub. `task check` is therefore red on `test`.
-- **First build task:** implement `ProcessNewVideo` (resolve transcript -> summarize -> deliver to
-  sinks | skip on no-transcript) to make the acceptance tests green, following the `.feature`
-  files. Then add the AI-router `Summarizer` (copy `llm` per ADR-004), the YouTube `VideoSource`
-  adapter (captions-first), and the store + brain sinks.
+- Clean Architecture core is implemented: `internal/domain` (entities), `internal/ports`
+  (interfaces), `internal/usecase.Engine.ProcessNewVideo` (resolve transcript → summarize →
+  deliver to sinks | skip on no-transcript). The acceptance tests in `test/acceptance/` are
+  green against it.
+- Adapters present under `internal/adapters/`: `youtube` (captions-first `VideoSource`,
+  timedtext/InnerTube acquisition per ADR-010), `summarizer` + `llm` (the copied AI router,
+  Primary→Fallback per ADR-004), `store` (Postgres, golang-migrate migrations 001–006),
+  `secrets` (file-backed `SecretStore`). The brain HTTP sink (ADR-005) is the remaining
+  optional sink.
+- Stage 1 is open (ADR-012): multi-user with **DB-enforced** isolation — Postgres RLS `FORCE`d
+  on all user-owned tables (migration 003), two-user isolation test in
+  `internal/adapters/store/rls_test.go`. Registration gate, per-user YouTube web connect, and
+  account management (disconnect / delete, ADR-013) all shipped.
+- `cmd/tapir` subcommands: `list`, `show`, `auth` (interactive host-side OAuth), `run` (batch
+  watch→summarize), `serve` (the HTMX+Templ web reader/writer under `internal/web`, a new
+  transport over the unchanged engine/ports — ADR-003). `tapir env` prints config.
+- **Build/run:** `task check` is the gate; `task build` produces the binary. Local dev uses
+  `StubAuth` (allow-all) and a `TAPIR_DB_DSN` Postgres; the deployed service uses Dex OIDC.
 
-**Unverified setup items** (see `docs/homelab-integration.md`, marked `confirm`): the Go version
-in `go.mod` (1.23 — match the koala runner; estate elsewhere uses 1.26.1), the brain-mcp URL, the
-exact ESO secret-ref naming, and the summarization model alias. Resolve against the live cluster
-before depending on them, and pin answers back into `docs/homelab-integration.md`.
+**Setup facts** (resolved — see `docs/homelab-integration.md` for the live values): LiteLLM is
+off-cluster at `koala:30401/v1/` with `LITELLM_MASTER_KEY` from 1Password; the summarization
+model is config (`TAPIR_SUMMARIZER_MODEL`, default `koala/phi4-mini`), never hardcoded. The
+brain-mcp base URL and ESO ref scheme are pinned in that doc; check it before wiring rather than
+re-deriving.
