patch

Stop skills from trying to reach user-invoked skills through the Skill tool: fix cross-skill references that violated the "no other skill can call it" invariant in .agents/invocation.md, in to-spec, wayfinder, to-tickets, triage, code-review, and diagnosing-bugs.

• to-spec, wayfinder, to-tickets, triage, and code-review each carried a precondition ("...run /setup-matt-pocock-skills if not") that PR #878 rewrote into a literal Call the Skill tool with "setup-matt-pocock-skills" instruction. setup-matt-pocock-skills is user-invoked, so none of these skills (user-invoked or model-invoked) can call it. Reworded all five as instructions for the agent to tell the human to run it instead.
• diagnosing-bugs's Phase 6 post-mortem hand off to improve-codebase-architecture (also user-invoked) the same way, from an autonomous, often-unattended bug-fixing flow with no human in the loop to catch the failed call. Removed the hand-off outright rather than softening it, since it rarely fired in practice. Phase 6 is now "Cleanup" only; the mechanical checklist is untouched.
• Added a carve-out paragraph to .agents/invocation.md's "Dependencies between them" section: the Call the Skill tool with "name" convention only applies when the named skill is model-invoked. This is the section PR #878 introduced without reconciling it against the user-invoked/model-invoked invariant stated eight lines above it; the gap is most of why this bug reached six call sites instead of one.

Fixes #453.
