Subject: [PATCH] fix(gsd): handle deleted cwd in projectRoot to prevent ENOENT
 crash

process.cwd() throws ENOENT when the worktree directory was deleted
during a failed merge. Every /gsd command calls projectRoot(), causing
the entire extension to crash.

Now catches the ENOENT and falls back to HOME directory.

Closes #3598
