docs: retire the META.md guidance ADR-0022 overruled, bump touched plugins

Why: ADR-0022 made `metadata.version` mandatory in SKILL.md frontmatter, but three documents still
instructed the opposite — that `version:`, `source:`, `references:` and `when:` belong in a separate
META.md. That recommendation was never implemented: META.md exists exactly once in this repo, inside
a vendored third-party research example, and all 39 skills now contradict it. A stale instruction
that outranks nothing is worse than no instruction, because an author following it undoes the ADR.

Implementation notes:
- Two LESSONS.md entries deleted outright — their entire payload was the rejected fix. Two kept and
  rewritten: the copy-fill entry loses only its META-TEMPLATE clause, and the `model:` entry keeps
  the provider-extension fact and the invocation-time boundary rule, which stand on their own.
- One factual error corrected in passing: the `extracted` slug entry claimed provenance is recorded
  in META.md. It lives in `references/sources.md` keyed by `source_keys:`, verified against
  validate-provenance.sh.
- Both docs/notes files gain `metadata.version` in their required-field lists. Deleting the stale
  paragraph while leaving those lists silent would have re-created the gap.
- `bin/write-docs` carried `metadata.version: "1.0"` — the only non-semver value in the corpus, and
  the result of relocating its old top-level `version:` without normalising it. Now `1.0.0`.
  ADR-0022 records the relocation it previously omitted, which issue #127 had asked it to decide.

Impact: patch bumps for the four plugins whose `.apm/` content changed — bin, git, gitea,
kyberforge. core and lint are untouched and stay put. Root apm.yml's `executables.allow` key and
marketplace package versions move in lockstep; the marketplace release version is unchanged.
