fix: Make ParseAgentBeadID accept any valid prefix (gt-w0fqg)

Browse Source 
Agent bead ID validation was hardcoded to only accept "gt-" prefix, which
caused errors when spawning beads polecats (which use "bd-" prefix):

  Error: invalid agent ID: agent ID must start with 'gt-' (got "bd-beads-polecat-pearl")

Changed ParseAgentBeadID to accept any 2-3 character prefix (gt-, bd-, hq-)
instead of hardcoding "gt-". Updated tests to cover other prefixes.
