chore(release): 0.2.1 — Griffin parity + CC 2.1.114 ingestion + live smoke

Focused parity patch addressing real gaps versus griffinmartin/opencode-claude-auth
HEAD df1b0cbc and ingesting CC 2.1.114 (wire-identical to 2.1.113).

Highlights:
- Bump FALLBACK_CLAUDE_CLI_VERSION 2.1.111 → 2.1.114
- Ingest 2.1.114 candidate manifest + per-version doc
- Add 'out of extra usage' marker to isLongContextError (Griffin PR #199)
- Defensive Haiku output_config.effort strip (Griffin PR #126)
- Document Haiku interleaved-thinking conflict-of-evidence in src/betas.ts
- New scripts/sandbox-live-smoke.ts gated on SMOKE_LIVE=1

Defers:
- enable1mContext from opencode.json agent options (Griffin PR #90):
  requires major plugin SDK upgrade 0.4.45 → 1.14.18; deferred to v0.3.0.
- Phase 4/5 from griffin-parity-and-cc-optimizations.md remain pending.
- cc_version SHA-256 RE (5 skipped tests) remains pending.
