#5 feat(LUKE-46): integrate existing Claude Code sessions

Summary

• Add a passive Claude Code main-process adapter that discovers local Claude session files without hooks, wrappers, MCP, controls, or provider-owned writes.
• Feed bounded, redacted observations into the shared session registry and expose normalized session state through narrow IPC.
• Show live sessions in the notch panel, with smoke fixtures limited to capture/evidence mode.
• Add synthetic adapter tests for transcript non-leakage, stale states, duplicate ids, and missing Claude data.

Evidence

• Platform-independent checks: ./scripts/check.sh passed
• macOS Electron verification (./scripts/verify.sh): embedded portable checks passed, then stopped with error: this command requires macOS in this Linux environment

• Scenario: smoke
• Physical-notch check: not performed by CI

Physical-device evidence

• Screenshot or screen recording: not attached
• Physical-notch check: not performed
• Device/display configuration: not recorded

Notes

• Local macOS smoke testing was reported working by the requester before this PR was opened.
• Blockers or follow-up verification: macOS visual evidence must come from CI or a physical Mac.
