Integrate Jira 'My Tickets' view into h-code #115

Summary

Add a Jira "My Tickets" view to h-code that surfaces assigned and recently viewed Jira issues, providing a quick-launch surface for starting or resuming agent threads tied to Jira work items.

Motivation

• Developers spend significant time context-switching between h-code and Jira to find what to work on next
• The existing seeded-work-item flow (Jira → slack → manager inbox) is manager-agent-oriented and not suited for individual developer daily workflow
• A "My Tickets" view would let developers see their Jira backlog directly in h-code, pick a ticket, and launch a worker thread with the ticket context pre-seeded

Proposal

A sidebar or panel that lists:

1. Assigned to me — Jira issues assigned to the authenticated user, ordered by priority/updated
2. Recently viewed — issues the user has interacted with in h-code
3. Watching — issues the user is a watcher on

Each ticket should show:

• Issue key (e.g. PROJ-1234)
• Summary/title
• Status, priority, assignee
• Quick action: "Start thread" (creates a worker thread with the Jira issue title + link as context)

Integration points

• Reuse the existing Jira API client / MCP integration for data fetching
• The Jira base URL is already configured per-project in the Todo panel (jiraBaseUrl)
• Could reuse the seeded-work-item writeback infrastructure for bidirectional sync (marking done in h-code → transitioning in Jira)

Scope decisions needed

• Where exactly in the UI does this live? Sidebar panel? Command palette command? Separate route?
• How is Jira auth handled? Is it the user's personal Jira token or a shared project token?
• Does this belong in the core app or as a MCP-server-provided view?

• Todo persistence ignores T3CODE_HOME and hardcodes ~/.t3code #111 (todo panel JIRA base URL — existing infra)
• MCP toggle server support already exists (mcp.listServers / mcp.toggleServer)
• Seeded work item writeback reactor (SeededWorkItemWritebackReactor) already handles Jira → h-code work item flow
