Garry Tan 45638297ba feat(gbrain-sync): queue primitives + writer shims
Adds bin/gstack-brain-enqueue (atomic append to sync queue) and
bin/gstack-jsonl-merge (git merge driver, ts-sort with SHA-256 fallback).
Wires one backgrounded enqueue call into learnings-log, timeline-log,
review-log, and developer-profile --migrate. question-log and
question-preferences stay local per Codex v2 decision.

gstack-config gains gbrain_sync_mode (off/artifacts-only/full) and
gbrain_sync_mode_prompted keys, plus GSTACK_HOME env alignment so
tests don't leak into real ~/.gstack/config.yaml.

# gstack-timeline-log — append a timeline event to the project timeline
# Usage: gstack-timeline-log '{"skill":"review","event":"started","branch":"main"}'
#
# Session timeline: local by default. If the user enables `gbrain_sync_mode`
# with the `full` (not `artifacts-only`) privacy tier — via the first-run
# stop-gate from `gstack-brain-init` or the preamble — timeline events are
# published to the user's private GBrain sync repo. See docs/gbrain-sync.md.
# Required fields: skill, event (started|completed).
# Optional: branch, outcome, duration_s, session, ts.
# Validation failure → skip silently (non-blocking).
