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.
Project-level skills (.opencode/skills/ and .claude/skills/) were not
discovered in desktop app environments because the discover functions
hardcoded process.cwd() to resolve project paths. In desktop apps,
process.cwd() points to the app installation directory rather than the
user's project directory.
Add optional directory parameter to all project-level skill discovery
functions and thread ctx.directory from the plugin context through the
entire skill loading pipeline. Falls back to process.cwd() when
directory is not provided, preserving CLI compatibility.
sisyphus-junior prompt always used todo-based discipline text regardless of
experimental.task_system setting because the useTaskSystem flag was never
forwarded from agent-config-handler to createSisyphusJuniorAgentWithOverrides.
