Verified on native Windows awin at the exact PR head with Electron CDP/Playwright: the Claude sign-in console is visible, cancellation after console launch restores Add Account state, and the login process/PID/temp cleanup completes.
* fix(win32): suppress Command Prompt window on IDE launches
- Prefer JetBrains GUI executables (`*64.exe`) over `.cmd` shims to avoid
console allocation (STA-3040).
- Use `start "" /B` when launching GUI apps via batch scripts; shims chain
through console helpers that allocate a visible prompt even with
`windowsHide`. `start /B` returns immediately, preventing the lingering window.
* fix(win32): suppress Command Prompt window on IDE launches
Prevent lingering Command Prompt windows when launching JetBrains IDEs
on Windows. Use `start "" /B cmd /d /c` so the nested shell exits with
the batch script, but only for JetBrains shims—VS Code and Cursor keep
the waiting form because `start` re-parses arguments and breaks remote
paths with spaces. Prefer colocated `*64.exe` executables beside the
resolved `.cmd` shim over PATH lookups to avoid stale installations.
* fix(win32): extend IDE launcher console suppression to direct paths
Support IDE paths stored directly in settings (e.g., idea.exe,
webstorm.cmd). Detect console idea.exe stubs alongside batch shims
for upgrade to GUI *64.exe. Fix start command title escaping: use
empty string instead of '""' to prevent libuv re-quoting.
The move of hasUnsafeWindowsBatchSyntax into src/shared/windows-batch-spawn.ts
silently added `(` and `)` to the cmd.exe denylist, so every .cmd shim or
argument path containing parentheses became unspawnable across nine call sites.
Parentheses only group commands and cannot chain one without a separator the
guard already rejects, so they are dropped again.
The rejected character set is now the single source for the user-facing error
strings, and `orca account add` translates the sentinel into a real message.
