fix(kyberforge): resolve PR #91 review findings in apm docs and orchestrators

Addresses 7 verified findings from the /code-review pass on PR #91's
APM-conversion changes:

- apm-workflow's description omitted install triggers, misrouting
  "install my apm dependencies" requests to apm-install instead
- `apm marketplace check` was listed under both the marketplace and
  audit dispatch rows, breaking the "one reference file per action"
  contract; kept under marketplace.md, its real usage-sequence home
- ADR-0015 claimed apm-workflow docs are generic/repo-agnostic while
  marketplace.md cited this repo's AGENTS.md and git-commits/
  git-remotes skills by name; stripped the holocron-specific
  citations (marketplace.md, compile.md) so the claim now holds
- plugin-author/marketplace-author are superseded per ADR-0015 with
  deletion deferred to #90; added deprecation notices pointing to
  the replacing apm-workflow dispatch actions
- apm-orchestrate/gitea-orchestrate/git-orchestrate all instruct
  dispatch "via Skill" without granting the Skill tool; added it to
  all three
- apm-orchestrate mandated strictly sequential fan-out across
  independent packages with no shared state; relaxed to permit
  parallel dispatch, matching this repo's own subagent-parallelization
  guidance

+> **Deprecated:** Superseded by `apm-workflow` per ADR-0015 — deletion pending issue #90 (not yet changed). Use `apm-workflow marketplace` (`apm marketplace init`/`package add`/`check`) for CREATE/ADD/REMOVE/UPDATE and `apm-workflow compile` (`apm pack` emits `.claude-plugin/marketplace.json`) instead.

 ## Gotchas
 
 - Both marketplace files must be identical after every operation — never update one without the other in the same edit pass.
