Summary

Selectively port the requested Claude Desktop and Pi AI session parsers from b08x, adapted for Firstsun's multi-home sync and source isolation. Refs #31 and #36.

• Claude Desktop: discover <home>/.../local-agent-mode-sessions/<account>/<project>/<session>/audit.jsonl, read adjacent metadata, parse audit files with explicit namespaced session IDs (the shared parser normally rejects non-UUID filename audit.jsonl).
• Pi AI: discover <home>/.pi/agent/sessions/**/*.jsonl, ingest turns/tool calls/usage/compactions with namespaced IDs.
• Preserve message parent linkage, avoid collisions between tools/homes using a stable source+absolute-path hash and source-qualified message IDs.
• Use existing homeRoot source discovery. Explicit opt-in: code-insights sync --source claude-desktop or code-insights sync --source pi; plain sync won't automatically import them.
• Add realistic filesystem-fixture tests and registry assertions.

Risks / review required

• CI Build/Test on Node 24 + pnpm 12: https://github.com/firstsun-dev/code-insights/actions/runs/40624440466
• Manual smoke with genuine Claude Desktop local-agent audit files; verify format compatibility, session count and metadata.
• Manual smoke with genuine Pi AI sessions across model/usage/tool-result variants.
• Multi-home repeated sync, pricing and deduplication checks.
• UI source filters and badges verified.

No DB migration, no change to default sync sources, no production deploy. Draft PR only until manual fixture validation is complete.
