Garry Tan c5ed2d6f90 fix: pre-landing review auto-fixes (5 correctness + observability)
/ship Step 9 review surfaced 9 INFORMATIONAL findings on the new helper +
migration. Five auto-fixed with no behavior regression (26/26 tests pass):

bin/gstack-gbrain-source-wireup:
- Version compare: put floor "0.18.0" first in `sort -V` stdin so equal-or-
  greater $v always sorts to position 2. Stable across sort implementations.
- _worktree_add_detached: drop `2>/dev/null` on the `worktree add`, surface
  git's stderr through `prefix` so users see WHY adds fail (disk, perms).
- ensure_worktree: same observability fix on the `git checkout --detach` path
  during HEAD-advance, so users see the actual git error before recovery.
- do_probe: replace `[ -d X ] || [ -f X ] && set=present` (precedence trap —
  the `&&` short-circuits when the dir branch fails) with explicit if-block.
- do_probe: capture `check_source_state`'s return code explicitly via
  `set +e; ...; rc=$?; set -e`. `$?` after an `if`/`elif` chain is fragile
  under set -e and may not reach the elif under some shell versions.
- do_wireup: same explicit return-code capture for `ensure_worktree`. The
  prior `ensure_worktree || { if [ $? = 2 ]; ...` pattern relied on `$?`
  reflecting the function's return after `||`, which is implementation-defined.

gstack-upgrade/migrations/v1.15.1.0.sh:
- Trim whitespace from `gstack-config get gbrain_sync_mode` output via
  `tr -d '[:space:]'`. Trailing newlines would mis-classify "off\n" as a
  non-empty non-off mode and incorrectly invoke the helper.

Skipped findings (cosmetic / out of scope):
- `python3 -c` reads `~/.gbrain/config.json` via `expanduser` instead of
  the helper's `$GBRAIN_CONFIG` variable (cosmetic; HONORS HOME override).
- Long sync-failure error message could truncate to last N lines (cosmetic
  log readability).

Garry Tan e36ff7dd4c feat: helper locks GBRAIN_DATABASE_URL at startup, defends against config rewrites
The wireup helper previously read ~/.gbrain/config.json on every gbrain
subprocess invocation. On Garry's Mac, multiple concurrent test runs and
agent integrations were rewriting that file mid-sync, redirecting the
wireup at the wrong brain partway through a 4-min initial import.

This commit adds a `--database-url <url>` flag to the helper and locks
the URL at startup. Precedence:
  1. --database-url flag                       (explicit caller intent)
  2. GBRAIN_DATABASE_URL / DATABASE_URL env    (CI / manual override)
  3. read once from ~/.gbrain/config.json      (default)

Whichever wins gets exported as GBRAIN_DATABASE_URL for every child
`gbrain` invocation. Per gbrain's loadConfig at src/core/config.ts:53,
env-var URLs override the file URL — so a process that flips config.json
between two of our gbrain calls can't redirect us. Defense-in-depth:
once the URL is locked, the wireup completes against the original brain
even under hostile filesystem conditions.

setup-gbrain/SKILL.md.tmpl Step 7 now reads the URL out of config.json
once (via python3 inline) and passes it explicitly with --database-url,
so even the very first wireup call is decoupled from config.json mutability.

Three new test cases cover the lock behavior:
  - --database-url flag is exported to child gbrain calls
  - falls back to ~/.gbrain/config.json when no flag and no env
  - flag overrides env GBRAIN_DATABASE_URL and config.json values

The fake gbrain in the test suite now records GBRAIN_DATABASE_URL alongside
each call so tests can assert the helper exported the locked URL.

Total test count: 13 → 16 passing.

Garry Tan b21bf34893 feat: gstack-gbrain-source-wireup helper + 13 unit tests
The new bin/gstack-gbrain-source-wireup is the single helper that registers
the gstack brain repo as a gbrain federated source via `git worktree`, runs
incremental sync, and supports --uninstall + --probe + --strict modes.

Replaces the dead `consumers.json + ingest_url + /ingest-repo` HTTP wireup
introduced in v1.12.0.0 — that endpoint never shipped on the gbrain side.
The federation surface (`gbrain sources` / `gbrain sync`) shipped in gbrain
v0.18.0; this helper adapts to its actual semantics (no `sources update`, so
path drift recovery is `remove + re-add`; no `--install-cron` either, so
freshness rides on the existing skill-end push hook).

Source-id derivation is multi-fallback: ~/.gstack/.git origin URL →
~/.gstack-brain-remote.txt → --source-id flag. This makes `--uninstall`
work even after `~/.gstack/.git` is destroyed by the parent uninstall script.

Worktree is `--detach`ed at $GSTACK_HOME's HEAD because main is already
checked out there; advance is a re-checkout of the parent's current HEAD,
not a `git pull`. Divergence recovery removes + re-adds the worktree.

Test suite covers 13 cases: fresh-state registration, idempotent re-runs,
drift recovery, --strict failure modes, source-id fallback chain, --probe
non-mutation, sync errors, and --uninstall. Fake gbrain on $PATH, real git
ops at GSTACK_HOME tmp dir.
