fix(ci+contractiles): canonicalise checkout SHAs and complete contractile migration

CI SHA drift: normalise all actions/checkout pins across 11 workflows to the
estate canonical de0fac2e (v6.0.2); update workflow-linter.yml example label.
dogfood-gate.yml: SHA-pin two previously @main first-party actions (a2ml-validate,
k9-validate) to current HEAD.

Contractile layout: complete the trident migration to canonical
.machine_readable/contractiles/<verb>/<Verb>file.a2ml + <verb>.ncl:
- add intend/ and adjust/ (were entirely missing)
- add must.ncl, trust.ncl, dust.ncl (runners were absent)
- replace bare Mustfile/Dustfile (no extension) with proper Mustfile.a2ml
- replace TOML-style Dustfile.a2ml with canonical A2ML format
- migrate K9 to .machine_readable/svc/k9/ (K9 is SVC, not a contractile)
- delete top-level contractiles/ directory (was drift)
- delete .machine_readable/INTENT/ADJUST/MUST/TRUST.contractile (S-exp legacy)
- update contractile.just source dir comment to point at new location
