fix(apm-workflow): type: selects processing, it does not validate content

configure.md said apm.yml's `type:` field "constrains what .apm/ may
contain" and that changing it later "does not retroactively validate what
is already on disk" — both implying a validation step that does not exist.
Read against the installed apm-cli 0.28.0: PackageContentType controls how
a package is processed during install/compile, apm_package.py only
enum-checks the declared string, and validate_apm_package() branches on the
structural type derived from files on disk, never on the declared field.
There is no content-vs-type mismatch check anywhere.

The hazard is therefore the opposite of what the wording primed for:
silent omission. A package declaring type: instructions while shipping
.apm/skills/ installs no skill and compiles AGENTS.md only, exits 0, and
reports success having shipped none of its primitives. The rule is now to
verify deployed output rather than the exit code. apm-orchestrate carried
the same wording as a Hard Rule and is corrected in step; its separate
defects stay with #120.

Also refreshes the exemplar figures this branch had re-staled. 264a5db set
them to 3,222 words of references; 6cb47f8 then added 63 words and
invalidated them, and the correction above adds more. Re-measured after
all edits: body 237 and whole-file 304 both still hold, references total
3,416. body-discipline.md's "roughly 3,200" moves with it.

ADR-0020 is deliberately untouched — it self-pins its citations to
f9b919d — as is the git-commits negative example pinned to 5e23250.

 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.
 - Never guess the marketplace-add direction from context — resolve strictly from the operation name (`add-package` vs `add-marketplace`); see apm-workflow/references/marketplace.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.
+- `apm.yml`'s `type:` field routes processing (native skill install vs AGENTS.md compilation); it never validates `.apm/` content, and a mismatch is silent rather than an error. When scaffolding (`init-package`), set `type:` to cover every primitive the package will ship, and report the deployed output rather than the exit code — see apm-workflow/references/configure.md Gotchas.
 - 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`.
 - Check the `apm experimental enable registries` precondition before dispatching any operation that depends on a named registry, and fail with a clear diagnostic rather than silently no-op'ing like apm itself does — see apm-workflow/references/configure.md Gotchas for the underlying constraint (summarised in its SKILL.md Gotchas).
 - You are read-only against the working tree. Never create, edit, or delete a file — not an `apm.yml`, not a `.apm/` primitive, not compiled output, not a scratch note. `edit-config` is an operation you *route* to `apm-workflow`, never one you perform: dispatching it is allowed only when the caller asked for that edit, never as your own repair of something you noticed.
