fix: increase OpenClaw E2E test timeouts to 5min/6min

Agent calls inside Docker need more time for cold start + LLM API
round trips. Spawn timeout 120s -> 300s, test timeout 180s -> 360s.

+### Added

+- `gbrain check-update` command with `--json` output. Checks GitHub Releases for new versions, compares semver (minor+ only, skips patches), fetches and parses changelog diffs. Fail-silent on network errors.
+- SKILLPACK Section 17: Auto-Update Notifications. Full agent playbook for the update lifecycle: check, notify, consent, upgrade, skills refresh, schema sync, report. Never auto-upgrades without user permission.
+- Standalone SKILLPACK self-update for users who load the skillpack directly without the gbrain CLI. Version markers in SKILLPACK and RECOMMENDED_SCHEMA headers, with raw GitHub URL fetching.
+- Step 7 in the OpenClaw install paste: daily update checks, default-on. User opts into being notified about updates, not into automatic installs.
+- Setup skill Phase G: conditional auto-update offer for manual install users.
+- Schema state tracking via `~/.gbrain/update-state.json`. Tracks which recommended schema directories the user adopted, declined, or added custom. Future upgrades suggest new additions without re-suggesting declined items.
+- `skills/migrations/` directory convention for version-specific post-upgrade agent directives.
+- 20 unit tests and 5 E2E tests for the check-update command, covering version comparison, changelog extraction, CLI wiring, and real GitHub API interaction.
+- E2E test DB lifecycle documentation in CLAUDE.md: spin up, run tests, tear down. No orphaned containers.
+
+### Changed
+
+- `detectInstallMethod()` exported from `upgrade.ts` for reuse by `check-update`.
+
+### Fixed
+
+- Semver comparison in changelog extraction was missing major-version guard, causing incorrect changelog entries to appear when crossing major version boundaries.

+2. **Check if the port is free:**
+   `docker ps --filter "publish=PORT"` — if another container is on that port,
+   pick a different port (try 5435, 5436, 5437) and start on that one instead.
+3. **Start the test DB:**
+   ```bash
+   docker run -d --name gbrain-test-pg \
+     -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=postgres \
+     -e POSTGRES_DB=gbrain_test \
+     -p PORT:5432 pgvector/pgvector:pg16
+   ```
+   Wait for ready: `docker exec gbrain-test-pg pg_isready -U postgres`
+4. **Run E2E tests:**
+   `DATABASE_URL=postgresql://postgres:postgres@localhost:PORT/gbrain_test bun run test:e2e`
+5. **Tear down immediately after tests finish (pass or fail):**
+   `docker stop gbrain-test-pg && docker rm gbrain-test-pg`

+## Version migrations
+
+When shipping a GBrain version that requires agent action after upgrade (schema
+changes, changed defaults, deprecated commands), create a migration file at
+`skills/migrations/v[version].md`. The auto-update agent reads these files
+post-upgrade and executes the directives. See GBRAIN_SKILLPACK.md Section 17.
+
+If a release only has bug fixes with no behavior changes, no migration file is needed.
+
+## Schema state tracking
+
+`~/.gbrain/update-state.json` tracks which recommended schema directories the user
+adopted, declined, or added custom. The auto-update agent (SKILLPACK Section 17)
+reads this during upgrades to suggest new schema additions without re-suggesting
+things the user already declined. The setup skill writes the initial state during
+Phase C/E. Never modify a user's custom directories or re-suggest declined ones.

+
+## 17. Auto-Update Notifications
+
+GBrain ships updates frequently. The auto-update cron keeps users current by
+checking for new versions and messaging them when there's something worth upgrading to.
+
+The check is automatic. The upgrade is always manual — never install without
+the user's explicit permission.
+
+### The Check
+
+Run `gbrain check-update --json`. If `update_available` is false, stay completely
+silent — do nothing. If true, message the user on their preferred channel.
+
+### The Message
+
+Summarize the `changelog_diff` into 2-3 human-friendly bullets. No raw markdown.
+Lead with the most impactful change.
+
+> **GBrain v0.5.0 is available** (you're on v0.4.0)
+>
+> What's new:
+> - Semantic chunking now 3x faster with batched embedding
+> - New `gbrain files mirror` command for cloud storage migration
+> - Doctor command catches RLS misconfigurations
+>
+> Want me to upgrade? I'll update everything and refresh my playbook.
+>
+> (Reply **yes** to upgrade, **not now** to skip, **weekly** to check
+> less often, or **stop** to turn off update checks)
+
+### Handling Responses
+
+| User says | Action |
+|-----------|--------|
+| yes / y / sure / ok / do it / upgrade / go ahead | Run the **full upgrade flow** (see below) |
+| not now / later / skip / snooze | Acknowledge, check again next cycle |
+| weekly | Store preference in agent memory, switch cron to weekly |
+| daily | Store preference, switch cron back to daily |
+| stop / unsubscribe / no more | Store preference, disable the cron. Tell user: "Update checks disabled. Say 'resume gbrain updates' or run `gbrain check-update` anytime." |
+
+Acceptable "yes": any clearly affirmative response. When in doubt, ask again.
+**Never auto-upgrade.** Always wait for explicit confirmation.
+
+### The Full Upgrade Flow (after user says yes)
+
+**Step 1: Update the binary/package.**
+Run `gbrain upgrade`. This updates the CLI and all shipped files (skills, docs, migrations).
+
+**Step 2: Re-read all updated skills.**
+Re-read every skill file in `skills/*/SKILL.md` to pick up new patterns and workflows.
+Updated skills = better agent behavior. The user gets this for free.
+
+**Step 3: Re-read the production reference docs.**
+Read `docs/GBRAIN_SKILLPACK.md` and `docs/GBRAIN_RECOMMENDED_SCHEMA.md` fresh.
+
+**Step 4: Check for version-specific migration directives.**
+Look for `skills/migrations/v[version].md` files between the old and new version.
+If they exist, read and execute them in order.
+
+**Step 5: Schema sync — suggest new recommendations without undoing user choices.**
+Read `~/.gbrain/update-state.json` to see what the user previously adopted, declined,
+and customized. For each NEW recommendation in the updated schema:
+- If the user never saw it before, suggest it
+- If the user previously declined it, do NOT re-suggest
+- Never modify or remove the user's custom directories
+
+Update `~/.gbrain/update-state.json` with new choices and bump `schema_version_applied`.
+
+**Step 6: Report what changed.**
+Tell the user what was upgraded and what actions were taken.
+
+### Frequency Preferences
+
+Default: daily. Store in agent memory as `gbrain_update_frequency: daily|weekly|off`.
+Also persist in `~/.gbrain/update-state.json` so it survives agent context resets.
+
+### Quiet Hours
+
+Standard quiet hours gate (Section 9). Update notifications are never urgent.
+Hold for morning briefing.
+
+### Cron Registration
+
+Name: `gbrain-update-check`
+Default schedule: `0 9 * * *` (daily 9 AM)
+Weekly schedule: `0 9 * * 1` (Monday 9 AM)
+Prompt: "Run `gbrain check-update --json`. If update_available is true, summarize
+the changelog and message me asking if I'd like to upgrade. If false, stay silent."
+
+### Standalone Skillpack Users (no gbrain CLI)
+
+If you loaded this SKILLPACK directly (copied the file or read from GitHub) without
+installing gbrain, you can still stay current. Both this file and
+GBRAIN_RECOMMENDED_SCHEMA.md have version markers in their first lines:
+
+```
+<!-- skillpack-version: 0.4.1 -->
+<!-- source: https://raw.githubusercontent.com/garrytan/gbrain/master/docs/GBRAIN_SKILLPACK.md -->
+```
+
+**Self-update check:** Periodically fetch the first 3 lines of the source URL and
+compare the version marker against your local copy:
+
+```bash
+curl -s https://raw.githubusercontent.com/garrytan/gbrain/master/docs/GBRAIN_SKILLPACK.md | head -1
+# Returns: <!-- skillpack-version: X.Y.Z -->
+```
+
+If the remote version is newer (minor or major bump, same rule as the CLI), fetch
+the full file and replace your local copy. Do the same for GBRAIN_RECOMMENDED_SCHEMA.md.
+
+**Cron for standalone users:**
+Name: `gbrain-skillpack-update`
+Schedule: `0 9 * * 1` (weekly Monday 9 AM)
+Prompt: "Fetch the first line of https://raw.githubusercontent.com/garrytan/gbrain/master/docs/GBRAIN_SKILLPACK.md
+and compare the skillpack-version against my local copy. If newer, fetch the full
+file, re-read it, and tell the user what changed. Do the same for GBRAIN_RECOMMENDED_SCHEMA.md.
+If both are current, stay silent."
+
+This way standalone users get new patterns, workflows, and schema recommendations
+without installing the gbrain CLI. The agent fetches, diffs, and updates its own playbook.

+## Schema State Tracking
+
+After presenting the recommended directories (Phase C/E) and the user selects which
+ones to create, write `~/.gbrain/update-state.json` recording:
+- `schema_version_applied`: current gbrain version
+- `skillpack_version_applied`: current gbrain version
+- `schema_choices.adopted`: directories the user created
+- `schema_choices.declined`: directories the user explicitly skipped
+- `schema_choices.custom`: directories the user added that aren't in the recommended schema
+
+This file enables future upgrades to suggest new schema additions without
+re-suggesting things the user already declined.
