fix(deps): update gastown patch and pin beads to Go 1.24 compatible version

- Update gastown-fix-agent-bead-address-title.patch line numbers (326→315)
  for current upstream gastown source
- Remove obsolete gastown patches (rig-prefix, copydir-symlinks) that are
  now handled upstream
- Pin beads to 55e733c (v0.47.2) which uses Go 1.24.0 - newer versions
  require Go 1.25.6 which isn't in nixpkgs-unstable yet
- Remove beads-search-query-optimization.patch as it targets newer code
