fix(ci): unbreak estate-rules + A2ML gates introduced by #49 (#50)

## Summary

The tier‑2 bundle (#49) merged with two required gates red; they're now
failing on `main` and will fail every subsequent PR's CI. This is a
minimal follow‑up that closes both — no functional change to the tier‑2
work.

## Changes

- **`estate-rules.yml`** — the "AsciiDoc by default under `docs/`" check
flagged the **Documenter source pages** (`docs/src/*.md`) that #49 added
for the new docs build. Documenter's native source format is
**Markdown** — it cannot consume `.adoc` — so `docs/src/` is a
legitimate carve‑out, exactly like the existing `docs/wiki/` GitHub‑wiki
mirror. Added `-not -path 'docs/src/*'` to the check and updated the
comments/step name to document the carve‑out.
- **`.machine_readable/policies/MAINTENANCE-AXES.a2ml`** +
**`MAINTENANCE-CHECKLIST.a2ml`** — A2ML validation requires an identity
field (`agent-id`/`name`/`project`); these two were missing it. Added
`name` + `project` to each `[metadata]` block.

## Verification (local)
- `find docs -name '*.md' -not -path 'docs/wiki/*' -not -path
'docs/src/*'` → **empty** (no disallowed `.md`; `docs/legal/*.txt` and
`docs/governance/*.adoc` are unaffected).
- Both policy files now carry `name` + `project` in `[metadata]` (the
exact fields the validator's error named).

## Why this happened
Two parallel workers built #49 on disjoint file‑sets; the docs worker
added `docs/src/*.md` (Documenter) while the compliance worker wrote the
`estate-rules` docs check — neither saw the other's additions. Caught
here on the first real CI run and fixed at the workflow level.
