Phase 2: identity plumbing — group/member config, author: attribution

Config schema {owner,endpoint,key} -> {group, member, endpoint, key}:
- member (kebab-case slug, validated) is REQUIRED — who this machine
  writes as; group is the descriptive team name. CHORUS_GROUP/
  CHORUS_MEMBER env, config set --group/--member, doctor + config show
  both with sources, NOT-CONFIGURED (78) without a valid member.
- capture stamps author: <member> on every note (_build_note); bootstrap
  gains {{MEMBER}} substitution and stamps the seeded anchors; all 8
  scaffold templates + canonical frontmatter docs gain author:.
- New missing-author lint check: agent_written notes must carry author:
  (bootstrap marker exempt — plugin-owned).
- Lock owner is now <member>-<client>-<pid> (auto_owner); offline-queue
  records carry a member field for audit.
- build.py --bake-key bakes group/member/endpoint/key (--group/--member;
  member required + slug-validated) for per-member artifacts.
- Manifest -> 2.0.0-alpha.2; rebuilt chorus-memory.plugin.

Verified: 25/25 unit (+config/member checks), scaffold suite (+6 new
member/config assertions), routing-sync, 4 mock e2e (+capture-stamps-
author), run_eval metrics unchanged, +8 phase-2 smoke checks green.
