Ticket local files backend is complete and merged.

Implementation:

• 740b017 feat: add local ticket backend
• merge commit: 1041cdb merge: add local ticket backend

Summary:

• Added a new low-level ticket workspace crate.
• Added typed Ticket domain types and TicketBackend trait.
• Added LocalTicketBackend over the current work-items/ storage.
• Implemented list/show/create/add_event/review/set_status/close/doctor operations.
• Preserved current local storage layout and tickets.sh compatibility.
• Kept the implementation independent from pod, tui, Intake, Orchestrator routing, and scheduler code.
• Did not rename work-items/ or remove tickets.sh.

Review:

• External sibling reviewer approved with no blockers.
• Non-blocker follow-ups recorded in the implementation report/review:
  • event references are modeled but not persisted/parsed in thread.md yet;
  • write paths should avoid emitting extension values that tickets.sh doctor rejects unless the format is intentionally extended;
  • backend lock coordinates Rust callers but not direct concurrent tickets.sh writes;
  • inherited thread.md --- separator ambiguity remains.

Post-merge validation passed:

• cargo test -p ticket
• cargo fmt --check
• git diff --check
• ./tickets.sh doctor
• cargo check --workspace --all-targets
• nix build .#yoi --no-link
