fix: correct hook output schemas and marketplace registration

Stop hook was emitting hookSpecificOutput with hookEventName=Stop,
which is not a valid hookSpecificOutput type (only PreToolUse,
PostToolUse, UserPromptSubmit are). Changed to systemMessage.

SessionStart still uses additionalContext (confirmed working).

Stale /buddymon-fight and /buddymon-catch references in session-start.sh
updated to /buddymon fight and /buddymon catch.

install.sh now creates a full circuitforge marketplace with marketplace.json
so CC can validate the plugin name against the index before loading.
Removed invalid extraKnownMarketplaces local source (only github/git valid).
