chore(release): v0.9.20 — hotfix Codex Stop revert (#501)

v0.9.19 shipped #495 which chained session-end.mjs after stop.mjs on
the Codex Stop hook. Field-testing surfaced the underlying issue:
Codex fires Stop multiple times within a single conversation (once
per assistant turn), so chaining session-end marked sessions as
completed while later observations were still arriving.

#501 reverts the chain. Stop returns to summarize-only behavior. The
SessionEnd-shaped solution (a dedicated terminate event the agent
sends only once on real session end) tracks at #493.

Files bumped (9):
- package.json, packages/mcp/package.json
- plugin/.claude-plugin/plugin.json, plugin/.codex-plugin/plugin.json
- src/version.ts, src/types.ts
- src/functions/export-import.ts
- test/export-import.test.ts
- CHANGELOG.md

1034/1034 tests pass.

+
+Hotfix: revert the Codex Stop → session-end chain shipped in v0.9.19.
+
+### Fixed
+
+- **Revert Codex Stop hook session-end chain** ([PR #501](https://github.com/rohitg00/agentmemory/pull/501) by [@Rex57](https://github.com/Rex57), reverts v0.9.19's [#495](https://github.com/rohitg00/agentmemory/pull/495), re-opens [#493](https://github.com/rohitg00/agentmemory/issues/493)). Post-merge field-testing surfaced the underlying issue: Codex `Stop` fires before the overall conversation is truly finished — multiple Stops bracket each assistant turn within one session. Chaining `session-end.mjs` from Stop marked sessions completed too early, with later observations still arriving against an `endedAt`-stamped record. Restored to summarize-only Stop; the SessionEnd-shaped solution stays open as [#493](https://github.com/rohitg00/agentmemory/issues/493).

+
 ## [0.9.19] — 2026-05-18
 
 Feature + hardening wave. Sessions now link to the git commits they shipped (forward + reverse lookup, REST + MCP surfaces). OpenAI provider transport collapses into one shared module with auto-detected Azure URL style (legacy `/openai/deployments/<dep>` and v1 `/openai/v1` both supported). Graph retrieval switches from BFS to Dijkstra over the weighted edge graph. Codex Stop hook chains session-end. Plugin MCP server inherits `AGENTMEMORY_URL` / `AGENTMEMORY_SECRET` from the shell. Point fix routes the bundled iii-console installer around an upstream tag-prefix bug. 1007+ tests pass.
