Do not discard a stop request during startup.

The -Mode Stop path does not acquire $mutex. It can set $stopEvent after mutex acquisition but before this Reset() call. Reset() then clears the new request, and the tray ignores the stop command.

Serialize the startup reset and stop-event Set() operation with a shared gate, or use a startup handshake that distinguishes stale signals from new requests. The assertion in tests/windows-tray.test.ts, Lines 329-380, checks ordering but not this interleaving.

In `@src/tray/windows-tray.ps1` at line 72, Protect the startup reset of
$stopEvent in the tray initialization flow from racing with the -Mode Stop path:
serialize Reset() and the stop-event Set() operation using a shared gate, or
implement a startup handshake that preserves requests arriving after mutex
acquisition. Ensure new stop requests are not cleared before the tray begins
handling them, and update the relevant ordering test if needed.

P2 Badge Preserve literal-percent paths when launching the tray

When an installed Bun, CLI, or home path contains a literal environment-variable token such as %TEMP%—a legal Windows path already exercised by this test fixture—this branch launches the generated VBS file, whose WScript.Shell.Run expands environment variables in its command string even inside quoted paths. PowerShell therefore receives rewritten paths and the install/start command times out waiting for a heartbeat; before this change, spawnTray used launchWindowsTrayHost with fixed argv and preserved these characters. Keep the fixed-argv launch path here, or otherwise prevent WSH environment expansion.

Useful? React with 👍 / 👎.
