Configure the engineering skills against this repo and this KB

The Matt Pocock engineering skills (triage, to-tickets, to-spec, research,
implement) assume per-repo config for three things: where work items live, what
the triage label vocabulary is, and where domain docs sit. Nothing here declared
any of them, so every skill run re-guessed.

Frank's decisions, 2026-10-20: Gitea on Dankclaw as the tracker (no gh, no tea on
any box, so it is recorded as prose — auth via a 600 curl config, the endpoint
table, the 404-on-empty-token / form-encoded-merge / empty-200-on-merge traps,
and the AGENTS.md laws a skill must not renegotiate); the canonical triage label
vocabulary kept as-is, with the five labels created on the tracker (the repo had
zero, so nothing collides); single-context domain docs.

The configuration moved out of the skill's default docs/agents/ and into the one
knowledge base this repo allows: three pages under omp-docs/skills/, an empty
omp-docs/decisions/ carrying the ADR format rule, an "## Agent skills" pointer
block in AGENTS.md, index entries, and a log entry. The glossary is deliberately
not created — every candidate term already has an owner in system/, core/ or
skills/, and a term list that paraphrases them is a second owner of facts already
written down. Known cost: re-running setup-matt-pocock-skills will not recognise
omp-docs/skills/* and will offer to recreate docs/agents/; the AGENTS.md pointer
is what stops that.

Also closes a verification gap found on the way: kb-lint.bats only ever points
the linter at fixtures, so a page with no frontmatter or an index that stops
listing a file passes the suite silently. Two tests now run the linter and the
coverage checker against the shipped omp-docs/ tree.

+`setup-matt-pocock-skills` ran, and its output moved out of the skill's default
+`docs/agents/` into the knowledge base: [issue tracker](skills/issue-tracker.md)
+(Gitea on Dankclaw is the tracker — no `gh`, no `tea`, token via a `600` curl
+config), [triage labels](skills/triage-labels.md) (the five canonical roles,
