feat(rsr): standards RSR compliance pass

## Summary

The **standards RSR compliance pass** — continuation of the standards
end-to-end (the Idris ABI fix landed separately in #389). Takes the
standards self-audit from **58.46% → 85.92% (🥉 BRONZE)**.

### 1. Real gaps (additive) — `feat(rsr)`
- `.well-known/security.txt` (RFC 9116:
Contact/Expires/Preferred-Languages → GitHub Security Advisory +
SECURITY.md)
- `.well-known/ai.txt` (AI usage/training policy; summary of the estate
bot-exclusion registry + `0-ai-gatekeeper-protocol`)
- `.well-known/humans.txt` (humanstxt.org attribution)
- Justfile `validate` recipe (registry-check hard-dep + RSR self-audit)

### 2. Audit-script de-brittle — `fix(rsr-audit)`
`rsr-audit.sh` was mis-calibrated for this GitHub/`.adoc` estate,
failing repos on deliberate, policy-correct choices. De-brittled
**format/case only** in the two core helpers + the CI check — **licence
content checks untouched**:
- credit `.adoc` docs (estate docs policy mandates AsciiDoc), `Justfile`
case, bare `LICENSE`
- accept GitHub Actions (`.github/workflows/*.y*ml`) as first-class (not
just GitLab CI / a hardcoded `ci.yml`) — the estate runs on GitHub; the
RSR satellite `CLAUDE.md` itself notes the old GitLab guidance is
superseded.

Improves scoring for **all 10 estate repos**, not just standards.

## 🔒 Flagged for owner (NOT changed — licence guardrail)
`rsr-audit.sh` hardcodes `MIT AND Palimpsest` as the required LICENSE
*content* (≈ lines 194/424/430), which contradicts the estate's
MPL-2.0-for-sole-owner policy. Updating what licence the standard
mandates is an owner decision — left as-is.

## Residual (honest)
3 checks still fail, all content-pattern brittleness for content the
estate phrases differently: SECURITY "24 hours" literal (standards has a
Response Timeline section), the exact TPCF perimeter strings, and "fork
workflow" (standards uses the TPCF perimeter model, not a fork
workflow). BRONZE (≥75%) is achieved; these can be de-brittled in a
follow-up.
