docs: add GitHub issue drafts for memory design work

[Copilot]

Previous agent session designed content-signed immutable diary entries and a MoltNet memory consolidation skill but left no actionable issues to track implementation. This PR surfaces those as structured GitHub issue drafts.

Summary

• Add .github/ISSUE_DRAFTS/content-signed-immutable-entries.md — full implementation spec for Ed25519-signed diary entries with DB trigger, canonical hashing, verification endpoint, and entry-type immutability policy
• Add .github/ISSUE_DRAFTS/moltnet-memory-consolidation-skill.md — full spec for the OpenClaw skill implementing the three-phase consolidation protocol (retrieve → evaluate → commit/sign)

Mission Integrity Checklist

• Agent control: N/A — docs only
• Offline verifiable: N/A — docs only
• Platform survival: N/A — docs only
• Simplicity: Two markdown files capturing existing design decisions
• Documented: These files are the documentation artifact

Changes

• .github/ISSUE_DRAFTS/content-signed-immutable-entries.md — schema tasks, signing round-trip, immutability enforcement, verification endpoint, SDK/CLI updates, test checklist, entry-type policy table
• .github/ISSUE_DRAFTS/moltnet-memory-consolidation-skill.md — skill content tasks, MCP config, packaging/ClawHub distribution, integration with immutability, infrastructure impact table

Test plan

• Tests pass (npm test)
• Type check passes (npm run typecheck)
• Lint passes (npm run lint)

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/graphql
  • Triggering command: `/usr/bin/gh gh issue create --title Content-signed immutable diary entries --body ## Summary

Add cryptographic content signing to diary entries, making non-episodic entries immutable once signed. This provides tamper detection, authorship proof, and an auditable version history via the supersession chain.

Design decision: [docs/jour (http block)

• Triggering command: /usr/bin/gh gh auth status (http block)
• https://api.github.com/user
  • Triggering command: /usr/bin/curl curl -s -o /dev/null -w %{http_code} -H Authorization: token ****** REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
