v0.15.1-beta

Fixes the Windows ConPTY first-byte-drop bug at its root with quiescence-based shell detection, replacing fragile fixed delays with adaptive output polling.

What's Changed

Bug Fixes

• ConPTY first-byte-drop (root cause fix) — replaced the 80ms fixed delay with waitForOutputQuiet, which polls PTY output timestamps and resolves once output has been silent for 100ms. Handles slow shell profiles (oh-my-posh 800ms+) without wasting time on fast ones
• Shell-ready detection for non-standard prompts — added quiescence fallback for prompts that don't match regex patterns (oh-my-posh with custom glyphs, etc.). Terminal goes quiet for 250ms → considered ready
• AI session launch reliability — interactive AI sessions now adapt to actual shell startup time instead of using a fixed delay

Improvements

• TERMINAL_WRITE_SAFE IPC channel — new quiescence-aware terminal write used by agent launch and AI session manager
• Workspace pill sorting — auto-sort now respects most-recently-selected order within activity tiers
• Workspace pill component refactor — extracted WorkspacePillReorderItem for cleaner drag/reorder separation
