refactor(machine-readable): estate canon migration (descriptiles / bot_directives / contractiles) (#39)

Item 3 of the hygiene pass. **Leads the estate rename** (ahead of
standards, per your call) and adopts the standards contractile canon.

## Structure
- `6a2/` → **`descriptiles/`** (6 core a2ml files); `anchors/` moved
underneath it
- `agent_instructions/` → **`bot_directives/`**
- `contractiles/` → standards **6-verb canon**: `must / trust / adjust /
dust / bust / intend`, each a trident (`<Verb>file.a2ml` + `<verb>.ncl`
+ `<verb>.k9.ncl`) + `<verb>.manifest.a2ml`, plus `INDEX.a2ml` +
`_base.ncl`. (`bust` = breakage/expiry/hard-stop; `lust` retired into
`intend`.)
- `CLADE.a2ml`: template residue → `a2ml-validate-action` (kept `rm`
clade prefix)
- Path-ref fixes in consumers (`0-AI-MANIFEST`, `validate-a2ml.sh`,
`Justfile`, `MAINTENANCE-CHECKLIST.a2ml`) — incl. pre-existing
root-vs-`6a2` path bugs
- Deleted cruft: root `contractiles/`, root
`.machine_readable/*.contractile`, stale `docs/templates/contractiles/`

66 files: 23 add, 21 delete, 13 rename, 9 modify. All hook-clean
(renames are pure moves; new files are `.a2ml`/`.ncl`).

## ⚠️ Deferred (need you)
1. **Contractile DATA fill** — seed templates carry ADOPTER
INSTRUCTIONS; the **gating** contracts (`must`/`trust`) must be authored
by you, not generated. Old Purpose/Anti-Purpose content is in git
history.
2. **`.adoc` reference updates** (`ai/README`, `AI-CONVENTIONS`,
`bot_directives/README`) + a contractiles `README` — blocked by the
pre-commit hook, which **requires the MPL owner-string and rejects
CC-BY-SA docs** (a hook/policy mismatch worth fixing). Belongs to your
header pass.
3. **`CLADE.a2ml` `uuid` + `[clade]`/`[lineage]`** — the `uuid` still
collides with rsr-template-repo; reconcile in `gv-clade-index`.
