Summary

Automatically transition ticket status when parsec lifecycle events occur. This turns parsec from a worktree manager into a complete development workflow hub.

Proposed Behavior

[tracker.auto_transition]
on_start = "In Progress"
on_ship = "In Review"
on_merge = "Done"

$ parsec start CL-2283
Created workspace for CL-2283...
  ✓ Ticket status → In Progress

$ parsec ship CL-2283
Shipped CL-2283!
  PR: https://github.com/org/repo/pull/42
  ✓ Ticket status → In Review

$ parsec merge CL-2283
Merged PR #42!
  ✓ Ticket status → Done

Implementation Notes

• Jira: query available transitions via GET /issue/{key}/transitions, match by name, then POST /issue/{key}/transitions
• GitHub Issues: PATCH /repos/{owner}/{repo}/issues/{number} with state field
• Should be opt-in via config (disabled by default)
• Transition failure should warn but not block the operation

Priority

High — killer feature that differentiates parsec from plain worktree tools
