Event logging

The plugin triggers three Moodle events. They appear in the standard Moodle logs.

Event class	Name	CRUD	Data
\local_mcp\event\tool_called	MCP tool called	read	userid; courseid when the tool works on a course; other: tool (name), status (success or error), summary (short argument summary).
\local_mcp\event\token_issued	MCP access token issued	create	Table local_mcp_token; userid and relateduserid; other: clientid, scopes, tokentype.
\local_mcp\event\token_revoked	MCP token revoked	update	Table local_mcp_token; userid and relateduserid; other: reason, tokentype.

build_course runs as a background task; when it finishes, the task triggers its own tool_called event for build_course with the final status.

All three use education level "other".

• In the argument summary, argument names that look like tokens, secrets or passwords are redacted.
• Raw tokens are never logged.
