chore(release): bump all six plugin versions for the ADR-0020 retrofit

No wave on this branch bumped a version across 56 commits, though
apm-workflow's own configure.md states the policy: bump a package's
apm.yml version: whenever anything reaching its compiled output changes.
All six local packages have substantive .apm/ edits here.

Minor rather than patch. The retrofit rewrote every skill description,
which is the routing surface a caller matches against, and redistributed
bodies into references/. Behaviour is preserved but discovery changes, so
this is more than a fix.

The same file is explicit that versions are per package — editing
plugins/foo/.apm/ never bumps plugins/bar — so this is six independent
bumps that happen to land together, not one release number. Under the
per_package strategy the catalog carries a second copy in
marketplace.packages[], and apm-marketplace-check fails the push when the
two disagree; it cannot see a bump skipped in both, which is the state the
branch was in.

executables.allow is version-pinned by apm's design and moves with
kyberforge, or the SessionStart hook silently stops deploying (ADR-0019).
The comment above that block predicted exactly this; the pre-push suite
caught it when the first bump orphaned the key.
