Development Timeline

v0.12.0 — Forge providers, faster cold start, and a fleet broadcast rework

• Forge provider model — git host integration is no longer tied to GitHub, with the provider set per project and overridable per worktree
• Faster cold start — the boot path batches its initial invoke and runs hydration concurrently, with memory-pressure handling that scales as load climbs
• Virtualized worktree sidebar — rows now show dirty state, last commit, base-branch divergence, and fetch staleness
• Fleet broadcast rework — per-target edit and skip, fuzzy matching in the picker, and saved fleets split into pinned and smart sets
• MCP server — audit tooling with NDJSON export, time-bounded per-tool grants, and a cap on repeated auth failures
