fix: improve Windows UX and stabilize chat/session behavior across runtimes (#693)

* fix: preserve unsent prompt when adding editor context in VS Code

* fix: append Add to chat selections as markdown blocks with stable spacing

Convert selected assistant content to markdown before appending
Wrap each Add to chat selection in an `md` fenced block
Preserve multiline composer formatting across repeated appends

* fix: normalize persisted Windows paths to prevent identity mismatches

* fix: hide Windows subprocess console popups across server tasks

Hide OpenCode startup and shell command child windows in the web server
Apply windowsHide to cloudflared and skills-catalog git subprocesses
Cover remaining git service exec paths that could surface console windows

* fix: restore chat auto re-pin when reaching bottom

Re-pin now triggers when scrolling back into the bottom zone, not only via the button.
Upward user scroll intent still unpins immediately and is not overridden by re-pin.
Unified bottom/re-pin threshold logic to reduce sensitivity mismatches.

* fix: restore chat scroll release on mobile during streaming

Restores pinned-scroll release on touch scroll up so mobile users can leave auto-follow while streaming.
Improves re-pin behavior near bottom to avoid sticky or inconsistent pin states.
Includes related chat UI and dependency updates in the same change set.

* fix: hide daemon startup probe consoles on Windows

* fix: prevent pinned scroll tug-of-war during streaming

* fix: prefer git.exe to avoid Windows diff popup flashes

* fix: prefer git.exe discovery in Windows git flows

* fix: avoid where probes in Windows git resolution

* fix: avoid update-check subprocess flashes on Windows

* fix: normalize read file path labels

* feat: add OpenChamber defaults and improve theme ports

Add new OpenChamber light and dark themes
Regenerate imported themes with stronger surface mapping
Set OpenChamber themes as the default top options

* fix: stabilize chat pin and unpin behavior during streaming

Restores reliable unpin on upward wheel and touch gestures while auto-follow is active.
Prevents immediate re-pin while the user is actively scrolling upward near the bottom.
Keeps smooth follow-to-bottom behavior while reducing scroll tug-of-war.

* fix: suppress Windows command popups in VSCode runtime processes

Hide spawned git and server process windows in VS Code runtime
Extend hidden-window handling to server port cleanup and reveal commands
Keep behavior unchanged on non-Windows platforms
