Garry Tan 55e7ed9fec fix: pre-landing review fixes (datamark, DRY, compact, coverage)
Addresses the pre-landing review findings (all INFORMATIONAL, no criticals):
- security: datamark resurfaced decision text at the render boundary
  (lib/gstack-decision.ts datamark() — neutralizes code fences, --- banners,
  <|role|>/</system> markers, control chars, newlines). Applied in
  gstack-decision-search human output so stored text can't masquerade as
  instructions in Context Recovery (codex hardening #3 / AC #7). --json stays raw.
- DRY: extract resolveSlug/gitBranch/flagValue to lib/bin-context.ts; both
  decision bins use it instead of duplicating the helpers.
- compact(): batch the archive append (one write, not N) and shrink the
  mid-compact crash window; simplify the opaque branch/issue ternary.
- coverage: learnings-log injection rejection (D2A wiring), search --recent/
  --scope + NaN-safe --recent, datamark-applied, unparseable lock body,
  compact-empty, corrupt-snapshot degrade.

/**
* bin-context — tiny shared helpers for non-interactive gstack bins that need the
* project slug, current branch, and argv flags. Extracted from the decision bins
* (gstack-decision-log / gstack-decision-search) so the slug/branch/flag plumbing
* lives in one audited place instead of being copy-pasted per bin.
