fix(omp): clamp OMP_AUTH_BROKER_URL/TOKEN, correct the env-allowlist docs

The docs claimed omp "has no documented vendor-key namespace of its own"
and "the multi-user clamp has nothing to gate" for omp — both false. Per
omp's own docs/environment-variables.md, it reads ~40 provider keys from
env (pi's known 34-key problem in the same shape), and its own knobs are
mostly PI_* (already globally allowlisted): PI_CONFIG_DIR,
PI_CODING_AGENT_DIR, PI_CODING_AGENT_SESSION_DIR, PI_SUBPROCESS_CMD,
PI_SHELL_PREFIX. The first three also move the ~/.omp tree
omp-session-resolver.ts/omp-transcript.ts hardcode, silently degrading
pinning/history — a known gap shared with pi, documented but not fixed
here.

The OMP_* prefix this PR adds brings in OMP_AUTH_BROKER_URL/
OMP_AUTH_BROKER_TOKEN, where omp resolves credentials from — the same
shape DEEPSEEK_BASE_URL is already dropped for in
clampEnvOverridesForOwner(). Add both to OWNER_CLAMPED_ENV_KEYS so a
non-granted owner in multi-user mode can't redirect them, and correct the
false claims in CLAUDE.md, docs/omp-integration.md, and the stale
resolveOmpHome() comment. Also documents omp's default
tools.approvalMode: yolo, which was previously unstated.

 **Docker cases**: a case can point at a **container**, with any of the CLI run modes running inside it. Like remote-SSH this is a **LOCATION OVERLAY on cases, never a `SessionMode` of its own**. Exactly one long-lived container **per case**, shared by all its sessions, so killing a session kills only that session's in-container tmux and **never** `docker stop` while siblings remain. The workspace is a real host dir bind-mounted at the **same absolute path**, which is what keeps file-routes/watchers on real host bytes and makes the in-container transcript projHash match the host. Credentials are **seeded** (RO mount, copied into the container once) rather than shared RW, so in-container CLIs never write refreshed tokens back to the host, and bind mounts are excluded from `docker commit` so exports stay secret-free. **NEVER a create-time `-e` for secrets, NEVER `--privileged`, NEVER the docker socket.** Config drift is detected via a label hash and a drifted launch is REFUSED rather than silently launched with stale config. ⚠️ On the loopback-only prod bind a container cannot reach 127.0.0.1, so in-container hooks need `CODEMAN_DOCKER_BRIDGE_HOOKS=1`; otherwise idle detection falls back to output-based. → [architecture-invariants#docker-cases](docs/architecture-invariants.md#docker-cases), `docs/docker-cases.md` (user guide), `docs/docker-cases-plan.md` (design)

Instead, `PredictiveEchoAddon` (separate `vendor/xterm-predictive-echo.js` bundle) paints each keystroke at the predicted cell while the wire path stays BYTE-IDENTICAL: the onData hook (`_predictHookOnData`) is a plain statement with no `return`, so control always falls through into the untouched send path — pinned by vm and E2E byte-identity tests. Predictions reconcile against the parsed buffer and only while the cursor sits on the measured composer row (`isCodexComposerRow`, `/^› /`).

Pi stays OUT of `isAltScreenStripMode()` (main-screen TUI, and its 0.84.0 fullscreen mode is runtime-switchable via `/settings`, where the alt screen is load-bearing), and lands on the `'buffer'` echo policy via the `_updateLocalEchoState` fallthrough.

 **Run launch synchronization**: the Run entrypoint holds an in-flight lock and disables `#runBtn` for the whole launch (≥500ms), so a double click cannot create duplicate sessions with the same `w<n>-<case>` name. `_ensureCreatedSessionVisible()` runs before `selectSession()`, and `_onSessionCreated()` stays an idempotent upsert, so POST-first and SSE-first ordering both produce exactly one rendered tab. ⚠️ **Closing has the mirror-image race and one owner**: `closeSession()` reads `wasActive` BEFORE its `await` and announces the delete via `_closingSessions`, while `_onSessionDeleted` skips the active-session handoff for an id in that set. Both used to read `activeSessionId` after the fact, so the `session_deleted` broadcast for your own delete could null it first and closing the tab you were on landed on the welcome screen instead of the next session, on the same build, depending on timing. The fallback also picks the first order entry that is still in `sessions` (a dead id can linger in `sessionOrder`, same reason Alt+N indexes a live-filtered list). A delete from ANOTHER client still shows the welcome screen, which is the honest answer when what you were looking at was taken away. Tests: `test/session-close-fallback.test.ts`. → [architecture-invariants#run-launch-synchronization](docs/architecture-invariants.md#run-launch-synchronization)
