fix: resolve claude CLI absolute path to prevent execvp failures

Browse Source 
When the web server runs in environments where `claude` isn't in PATH
(e.g., systemd services, non-login shells), node-pty's execvp(3) fails
with "No such file or directory". Fix by resolving the absolute path
to the claude binary using `which` with fallback to common installation
locations (~/.local/bin, /usr/local/bin, etc.). The resolved path is
cached for performance.
