Adds pf-guide, a guide to every part of Project Feed for agents on MCP or the pf CLI. Its SKILL.md routes to one reference per area: connection and conventions, posts and versions, media uploads, media review and annotations, tasks, docs, canvases, chat, handoffs, and the CLI.

Also rewrites task-workflow, plan-project, project-status, and work-triage, and folds in media-review-loop from #1 with corrections. The old version told agents to subscribe to MCP events, which are off on the hosted server.

Every claim was checked against the live staging tools/list and by calling the tools in a sandbox project. That turned up behavior the docs don't cover:

• get_task accepts PRO-42 and 42, but most write tools and get_post need the internal ID.
• Posts and tasks share one identifier sequence per project.
• get_post returns no files. list_media does.
• After a version drops a file, its annotations stay open but get_annotation_frame returns no image.
• create_post takes no idempotency key, and unknown arguments are rejected.

Behavior evals ran old and new skills on the same 9 tasks against staging fixtures, with Sonnet subagents. The graders check the resulting server state and call logs. The new skills pass 45 of 45 checks and the old ones 41 of 45. The old skills missed verification steps in plans, skipped a post with open feedback in a status report, failed lookups by identifier, and resolved a note on a dropped file without viewing it. The new skills use about 15% more tokens per run.

All client manifests move to 0.4.0. Supersedes #1.
