Subject: [PATCH 1/2] fix: open web UI to cwd-encoded URL so initial directory
 is correct
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The web command was opening the browser to a bare URL (e.g.
http://localhost:4096/) with no directory context. The server
middleware falls back to process.cwd() when neither the
x-opencode-directory header nor the directory query param are
present, but that only works correctly for the server process itself —
the browser-side frontend had no way to know which directory was
intended, and on some setups cwd resolves to /.

Fix: encode process.cwd() as a URL-safe base64 segment and append it
to the initial URL that is opened in the browser (e.g.
http://localhost:4096/<base64dir>). The frontend router already parses
this segment via DirectoryLayout and includes the directory in all
subsequent API calls via the x-opencode-directory header, so the
server now receives the correct context from the very first request.
