docs(aao-verified): pre-3.1 framing consistency sweep

[bokelley]

Refs #3564

Reconciles AAO Verified (Spec)/(Live) framing across docs and queued changeset entries before the 3.1 GA cut.

Changes

• docs/building/aao-verified.mdx — Renames the ## Two marks: AdCP Conformant vs AAO Verified section to ## Naming history so cold readers encounter the current single-mark framing, not a confusing two-marks heading. Also fixes a malformed 3-column table row in the same section (the | Both held | cell made the row render incorrectly in Mintlify).

• docs/building/conformance.mdx — Replaces the ⊆ containment notation (Verified (Spec) ⊆ Conformant via storyboards. Verified (Live) ⊆ Conformant …) with the independence-first phrasing established in docs(aao-verified): make Live independent of Spec #3536. The new line leads with the independence claim and its concrete examples (no test-mode endpoint → earn (Live) directly; test agent → earns (Spec) as complete claim), avoiding repetition of the "demonstrates conformance" sentence already on the line above.

• .changeset/salty-wasps-cheat.md — Removes "Same containment relationship as #3001 (Spec is a prerequisite for measuring Live)", which directly contradicts the orthogonal-axes correction in docs(aao-verified): make Live independent of Spec #3536. Replaced with "The two axes are orthogonal — neither is a prerequisite for the other (#3536)".

• .changeset/account-authorization-and-rbac-errors.md — Qualifies attestation_verifier as binding to the AAO Verified (Live) qualifier (not the unqualified "AAO Verified mark"), since the scope specifically enables (Live) axis observability.

• .changeset/aao-verified-framing-sweep.md — Empty changeset (docs-only, no protocol bump).

Non-breaking justification

All changes are non-normative doc and changeset text updates. No wire format, schema, task definition, enum value, or API shape is touched. Changeset entries are historical notes that don't affect protocol conformance. Existing clients are unaffected.

What's NOT in this PR (per issue scope)

• Item 4 (audit attestation_verifier docs once Define attestation_runner scope for AAO Verified (Live) canonical-campaign runner #3561 lands) — remains open on Pre-3.1 doc sweep: AAO Verified (Spec)/(Live) framing consistency #3564
• Items blocked by open implementation work (Define attestation_runner scope for AAO Verified (Live) canonical-campaign runner #3561, RFC: AAO Verified via canonical test campaigns (supersedes two-tier model in #2965) #3046)
• @adcp/client storyboard runner output strings — separate repo, flagged for maintainer

Pre-PR review

• code-reviewer: approved — no blockers. Fixed redundancy in conformance.mdx line 23 per nit; simplified "observability flow" phrasing to match existing doc language.
• docs-expert: approved — anchor audit clean (no inbound links to old #two-marks heading); line 116 "presumes" correctly left unchanged (tenant-isolation context, not Spec/Live hierarchy); agent-parseability improved.
