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).

# Migration: v1.15.1.0 — Wire existing brain-sync repos as gbrain federated sources
#
# Pre-1.15.1.0 /setup-gbrain wrote ~/.gstack/consumers.json with a placeholder
# `status: "pending"` and an empty `ingest_url`, expecting a gbrain HTTP
# /ingest-repo endpoint that never shipped. This migration runs the real
# wireup (gbrain sources add + worktree + initial sync) for users who
# already opted into brain-sync but never got the gbrain side connected.
#
# Idempotent: safe to re-run. Skips when:
# - User never opted into brain-sync (gbrain_sync_mode = off or unset)
# - No ~/.gstack/.git (brain-init never ran)
# - The wireup helper is missing on disk (broken install — defensive)
#
# Failure mode: invokes the helper WITHOUT --strict, so a missing/old gbrain
# CLI is a benign skip rather than blocking the rest of /gstack-upgrade.
