Add ProjectRootSource type ('env' | 'roots_list' | 'auto_detect') and
getProjectRootSource() getter to ConfigService. This enables downstream
consumers to determine how the project root was resolved and warn users
when auto-detection may have failed.
Emit projectRootWarning in parse_mode response when project root was auto-detected and no codingbuddy.config.json was found. This guides Cursor users to set CODINGBUDDY_PROJECT_ROOT environment variable. Update mcp.service mock to include new ConfigService methods.
Update Cursor adapter docs to include CODINGBUDDY_PROJECT_ROOT as required env var in .cursor/mcp.json template. Add explanation that Cursor may not support roots/list MCP capability. Closes #606
