Delegates to 'bd show' - all bd show flags are supported.
Works with any bead prefix (gt-, bd-, hq-, etc.) and routes
to the correct beads database automatically.

Examples:
  gt show gt-abc123          # Show a gastown issue
  gt show hq-xyz789          # Show a town-level bead (convoy, mail, etc.)
  gt show bd-def456          # Show a beads issue
  gt show gt-abc123 --json   # Output as JSON
  gt show gt-abc123 -v       # Verbose output`,
	DisableFlagParsing: true, // Pass all flags through to bd show
	RunE:               runShow,
