fix: Windows browse — stdio array format for Bun compatibility (v0.11.18.2)

[garrytan]

Summary

• Windows browse daemon fixed. The browse server wouldn't start on Windows because Bun requires stdio as an array (['ignore', 'ignore', 'ignore']), not a string ('ignore'). Two locations in browse/src/cli.ts (lines 237 and 239) updated to match the array format already used on line 243.
• Fixes Windows: browse.exe won't start (stdio bug) + cookie import completely non-functional #448, Windows: browse daemon fails with 'stdio must be an array' #454, browse.exe server spawn broken on Windows (Bun.spawn fails silently) (Permanent fix found) #458. Closes fix(browse): use detached child_process.spawn on Windows for server p… #444 (same fix, had merge conflicts).

Test Coverage

No new application code paths — format-only change to existing lines.

Pre-Landing Review

No issues found.

TODOS
