v0.2.0 — Codex adapter

First host adapter beyond Claude Code. Minor bump: new functionality, fully backward-compatible (existing Claude Code setups untouched).

Added

• Codex init adapter — tools/engramory_init.py codex bootstraps a Codex project: creates a memory store, writes a marked Engramory block into AGENTS.md, optionally installs the full protocol under .agents/skills/engramory (Codex auto-discovers Agent Skills there), and gitignores an in-project store. Idempotent on re-run.
• Codex adapter docs — adapters/codex/README.md. Honest reliability model: the index cap on Codex is rules + engramory_check.py, not a deterministic deny hook (the PreToolUse hook stays Claude-Code-only).

Hardened

• AGENTS.md block editing tolerates malformed markers from a hand-edit (reversed / dangling) — no crash, no silent data loss.
• Source tree validated up front (clear message instead of a raw traceback); --force help clarified; Python 3.9 compatibility fix.

Tests

• +5 (89 total): bootstrap, idempotence, external/kept memory roots, malformed-marker no-data-loss, --force replace-vs-keep.
