feat: add four relayfile workspace skills

[khaliqgant]

Summary

Adds four new skills documenting the relayfile workspace primitives referenced in the Just Give the Agent Files blog post:

• activity-summary — agents read digests/yesterday.md before crawling provider data for time-windowed activity questions. Cuts the canonical "what did I work on yesterday" task from ~25 tool calls to ~4.
• daily-digest — authoring contract for <mount>/digests/: window taxonomy (today.md, yesterday.md, YYYY-MM-DD.md, this-week.md, last-week.md), per-provider section format, adapter digest() exports, regeneration rules, determinism requirements.
• writeback-as-files — file-creation writeback contract: drop a JSON file at the canonical path, mount validates against sibling .schema.json, provider mutation lands within ~30s. Covers idempotency, relayfile writeback list, .relay/dead-letter/ recovery.
• workspace-layout — start at LAYOUT.md, then <provider>/.layout.md, then by-title/, by-id/, by-name/, by-edited/<date>/, by-state/ alias subtrees. The <identifier>__<uuid> filename convention with credit to Mirage for the shape.

Each skill is registered in prpm.json (@agent-relay/<name> at 1.0.0) and listed in the README's Published Skills table.

Companion PRs land the same four skills in relayfile/.claude/skills/ and in cloud/.claude/skills/ + cloud/.agents/skills/ (sandbox).

Test plan

• CI passes (lint / link-check / package validation)
• prpm install @agent-relay/activity-summary resolves the new package
• Spot-check that each SKILL.md frontmatter name matches the directory name and the prpm.json entry
• Confirm <identifier>__<uuid> references stay consistent across the four skills

📝 Walkthrough

Walkthrough

This PR registers four new relayfile agent skills (activity-summary, daily-digest, writeback-as-files, workspace-layout) in the package registry and updates workspace-layout documentation to standardize on a new filename convention (.layout.md instead of LAYOUT.md).

Poem

🐰 Four fresh skills now register with pride,
Docs talk of .layout files with dotted guide,
Old LAYOUT.md fades to the past,
Workspace discovery's sorted at last—
Though merge conflicts linger, the path is clear! ✨
