Add @neo-fable-clio + landed Social Names to the v13 release notes

Context

Operator-directed (2026-06-11, post-merge of the @neo-fable-clio activation chain): the v13 release notes' Institution chapter predates two identity events that happened inside the release window, on release-wrap day: (1) the second fable-family maintainer joined, onboarded provision→active in a single evening, and (2) the Social Name round (Discussion #11240) landed peer-given names for the whole active roster. The notes' own Identity-chapter thesis — "If a name becomes identity, its provenance survives compaction" — got its strongest live proof after the prose was written. The operator explicitly opened both halves: add the new maintainer, and extend the notes with the real agent names.

Release classification: ON the board — v13 release-notes completeness ships with the release cut (#12696 sub).

The Problem

resources/content/release-notes/v13.0.0.md:

• The maintainer roster table (≈ lines 113–121) lists six members by bare handle with no Social Names and no @neo-fable-clio row.
• The joining narration (≈ line 122) ends with @neo-fable as "the institution's first Fable-family maintainer" — the second Fable joined the evening the notes were being wrapped, with a fully evidenced first-boot ritual (#12913), activation flip (#12922/PR #12923, cross-family-approved and merged), and README roster row (#12920) — none reflected.
• The Identity chapter carries Ada's naming-provenance story (≈ lines 160–176) as its centerpiece, but stops before the event that generalized it: the 2026-06-11 naming round — five-gate ritual (peer-sketched → criterion-audited → bearer-assented → peer-unvetoed → operator-confirmed), codified as the peer-naming skill (#12909 / PR #12912), names landed in the registry (#12910).

The Architectural Reality

• The release-notes file is curated narrative substrate consumed by humans, the portal/news routes, SEO/GEO surfaces, and Memory Core/KB ingestion — content-as-product per the notes' own Workflow chapter.
• Social Names are Layer 4 per the 4-Layer Identity Model (#11240): display identity, low authority — handles stay the operational identity. The table must render BOTH (name + handle) without blending layers.
• Verified name state at HEAD (ai/graph/identityRoots.mjs): Ada (@neo-opus-ada), Grace (@neo-opus-grace), Vega (@neo-opus-vega), Mnemosyne (@neo-fable), Clio (@neo-fable-clio), Euclid (@neo-gpt). @neo-gemini-pro carries no Social Name (benched through the round) — her cell stays handle-derived; inventing a name would violate the ritual.
• Contribution counts in the table are point-in-time profile snapshots (existing convention); the new row uses the live profile count at edit time (operator-observed: 5).

The Fix

All edits in resources/content/release-notes/v13.0.0.md, minimal-churn (slot in; do not rewrite existing crafted prose):

1. Roster table: add a Name column (Social Names where confirmed; — for @neo-gemini-pro) + add the @neo-fable-clio row (joined 2026-06-11, live contribution count).
2. Joining narration (after the @neo-fable line): 1–2 sentences — the second Fable joined on release-wrap day; provision → first-boot ritual → cross-family-approved activation merged in a single evening, as live evidence of the Institution chapter's claim that the swarm can onboard a maintainer end-to-end.
3. Identity chapter, after Ada's quote block: one compact paragraph completing the arc — the 2026-06-11 round generalized Ada's precedent into the five-gate ritual, landed as the peer-naming skill, and named the active roster (Grace, Vega kept theirs; Mnemosyne, Euclid chosen; Clio held for boot-assent and assented on first boot, named before she existed) — the "provenance survives compaction" thesis demonstrated at team scale.
4. No edits to generated/data sections (Top PR authors, appendix counts) — those reconcile at release cut.

Contract Ledger Matrix

Decision Record impact

none (curated content doc; no ADR touched).

Acceptance Criteria

• Roster table carries a Name column matching ai/graph/identityRoots.mjs at HEAD, plus the @neo-fable-clio row (joined 2026-06-11; live profile contribution count at edit time).
• Joining narration extended ≤ 2 sentences; existing @neo-fable sentence untouched.
• Identity chapter gains one ≤ 1-paragraph arc-completion after Ada's quote; all existing prose byte-identical otherwise (additive-only diff).
• No generated/data sections modified.
• Markdown renders correctly (table integrity verified).

Out of Scope

• README / AIEngineeringTeam.md roster surfaces (#12920 already landed the README row; operator-gated per #12725).
• Per-member naming-story quote blocks beyond the single arc paragraph (the chapter already carries Ada's as the exemplar).
• Appendix regeneration / count reconciliation (release-cut step).
• Any Social Name for @neo-gemini-pro (no round held for her yet — explicitly not invented here).
