fix(kyberforge): resolve second round of PR #91 review findings

Two review passes on PR #91 (correctness + simplification) found the
prior fixup commit (d6fd9b6) left the deprecation notice it added
half-applied, cited a nonexistent ADR, and introduced/compounded a
few duplicate restatements of the same facts across apm-workflow's
skill files and apm-orchestrate's Hard rules.

- plugin-author/SKILL.md cited ADR-0016 (doesn't exist) instead of
  ADR-0006 for the version-parity invariant.
- The deprecation banner on plugin-author/marketplace-author wasn't
  reflected in their routing `description:` frontmatter, forge's
  routing table, either kyberforge README skill table, or CONTEXT.md
  — now propagated consistently; routing behavior is unchanged since
  issue #90 (repo-wide apm conversion) hasn't landed yet.
- apm-orchestrate's `configure` operation only covered scaffolding a
  new package, not editing an existing apm.yml (e.g. removing a
  marketplace.packages[] entry, which has no dedicated `apm` CLI verb
  and is just a manifest edit). Added `edit-config`, intentionally
  ungated — a local file edit isn't the same class of irreversible
  action as `apm publish`, and normal review already gates the commit.
- Deduplicated facts restated 3-4x across SKILL.md/references/ADR
  boundaries (audit semantics, reserved name prefixes, marketplace-add
  direction, registries precondition), and trimmed configure.md's
  ~55-line apm.yml schema dump — copied near-verbatim from the
  research doc — down to a compact key list with a pointer, matching
  install.md's existing terse cross-referencing style.

Deliberately left as-is: apm-orchestrate's parallel/sequential
fan-out logic stays inline rather than extracted to a shared
reference, since neither git-orchestrate nor gitea-orchestrate need
it yet — premature extraction for a single caller.

 These are non-negotiable regardless of `confirm` or any skill-local override:
 - `apm publish` claims a version on a registry — treat it as irreversible. Refuse without explicit `confirm: true`; always dispatch with `--dry-run -v` first and surface that output to the caller before the real publish, even when `confirm: true` was given.
-- `apm marketplace add` (registering a marketplace as a consumer) and `apm marketplace package add` (registering a local package into a marketplace being built) are opposite directions — resolve which one the caller means from the operation name, never guess from context alone.
+- Never guess the marketplace-add direction from context — resolve strictly from the operation name (`add-package` vs `add-marketplace`); see apm-workflow/SKILL.md Gotchas for why the two are easy to conflate.
 - `apm.yml`'s `type:` field constrains what `.apm/` may contain — when scaffolding (`init-package`), set `type:` before any primitive content is added; do not defer it.
 - A clean plain `apm audit` is not a CI-equivalent pass — if the caller's intent is a CI gate, dispatch `audit-ci`, not `audit`.
-- `apm experimental enable registries` must have already run before any `registry.*` config takes effect — check this precondition before dispatching an operation that depends on a named registry, and fail with a clear diagnostic rather than silently no-op'ing like apm itself does.
