chore: release v0.1.9

[cafitac]

Summary

• bump Python and npm package metadata to 0.1.9
• keep module __version__, package manifests, lockfile, and release metadata tests in sync

Release notes draft

v0.1.9 makes agent-memory substantially more usable as a real runtime attachment for Hermes, Codex, and Claude Code, while strengthening retrieval regression evaluation before future memory-ranking changes.

Highlights:

• stronger retrieval evaluation harness with fixture families, JSON reports, comparator baselines, selective baseline gates, soft advisories, and summary/delta breakdowns
• Codex and Claude Code wrapper scripts for invoking target CLIs with memory context
• prompt rendering fix so codex-prompt and claude-prompt include short retrieved-memory snippets, not only metadata/policy lines
• verified runtime attach readiness for Hermes, Codex, and Claude Code
• safer Hermes bootstrap merge behavior preserving existing hook indentation/list style
• improved onboarding docs and smoke coverage for fresh installs and existing Hermes hook users
• episode scope ranking fix so exact scope wins over stronger lower-priority rank signals

Validation

• uv run python scripts/check_release_metadata.py
• TMPDIR=/Users/reddit/Project/agent-memory/.tmp-test uv run pytest tests/ -q (115 passed)
• uv build
• npm pack --dry-run
• Previous isolated onboarding smokes passed for npm, uv tool, and pipx paths

Publish target after merge

• Python: cafitac-agent-memory==0.1.9
• npm: @cafitac/agent-memory@0.1.9

After this merges, publish by tagging v0.1.9 on main and pushing the tag.
