Category-based delegation (task(category='quick')) was broken because
SISYPHUS_JUNIOR_AGENT sent 'sisyphus-junior' to session.prompt but
config.agent keys are now display names ('Sisyphus-Junior').
- Use getAgentDisplayName() for SISYPHUS_JUNIOR_AGENT constant
- Replace hardcoded 'sisyphus-junior' strings in tools.ts with constant
- Update background-output local constants to use display names
- Add remapCommandAgentFields() to translate command agent fields
- Add raw-key fallback in tool-config-handler agentByKey()
Extends the process.cwd() fix to cover all project-level loaders. In the desktop app, process.cwd() points to the app installation directory instead of the project directory, causing project-level agents, commands, and slash commands to not be discovered. Each function now accepts an optional directory parameter (defaulting to process.cwd() for backward compatibility) and callers pass ctx.directory from the plugin context.
