fix: remove console.log statements, use console.debug where needed

Per Obsidian plugin submission requirements, only console.warn,
console.error, and console.debug are allowed.

Changes:
- Removed console.log from main.ts (API key generation and migration)
- Removed console.log from mcp-server.ts (server start/stop messages)
- Replaced console.log with console.debug in notifications.ts
- Updated tests to expect console.debug instead of console.log

All functionality is preserved - server status is still shown via
Notice and status bar, and tool calls are still logged when enabled.
