docs: D43-A — Phase 2 doc alignment (no code change) (#18)

* docs: D43-A — Phase 2 doc alignment (no code change)

Phase 1 was closed at v0.1.1 (multi-provider proxy core + pre-Phase-2
cleanup, D35-D42). This commit aligns documentation surfaces to the
Phase 2 reality before D43-B (ADR 0007 multi-key auth design draft) lands.

Pure doc cleanup — no .mjs / no tests / 4 files touched.

- CLAUDE.md release_kit.phase_rolling_mode:
  * current_phase: Phase 1 → Phase 2
  * current_pre_release_identifier: "0.1.0-bootstrap" → "0.2.0-phase2"
- README.md:
  * Status header now reads "v0.1.1 shipped (2026-05-25); Phase 2 in progress"
  * Implementation Status dated 2026-05-25; intro paragraph reflects Phase 1
    close + Phase 2 active
  * lib/keys.mjs row: "📋 Planned (Phase 2)" → "📋 Phase 2 active per ADR 0007
    (drafting at D43-B)"
  * Known limitations "Multi-key auth not yet implemented" note updated
  * Phase plan rewritten end-to-end: the original v0.1 spec planned one
    plugin per phase, but actual execution bundled the three Tier-D plugins
    + cache + fallback into a single Phase 1 milestone (v0.1.0+v0.1.1).
    New plan: Phase 0 ✅ / Phase 1 ✅ / Phase 2 multi-key auth (current) /
    Phase 3 dashboard / Phase 4+ v1.x roadmap / Phase N tier-2 opt-in.
- AGENTS.md § Key files to know:
  * lib/keys.mjs marker updated
  * Implementation-status-note dated 2026-05-25; reflects v0.1.1 close +
    Phase 2 active scope
- CHANGELOG.md Unreleased: D43-A entry recording the alignment per
  CLAUDE.md release_kit overlay phase_rolling_mode discipline.

Authority: CLAUDE.md release_kit overlay phase_rolling_mode — under
Unreleased; Phase 2 kickoff handoff at
~/.cc-rules/memory/handoffs/2026-05-25-phase-2-kickoff.md (committed in
cc-rules d9da966); ADR 0007 forthcoming at D43-B.

Test count: 468 → 468 (npm test verified locally before commit).

* docs: D43-A fold-in — ALIGNMENT.md phase terminology note (reviewer P2)

Fresh-context sonnet reviewer (PR #18) flagged P2: ALIGNMENT.md uses
"Phase 2"/"Phase 3" at lines ~58/~143-144/~179 with the original
per-plugin enablement meaning (Phase 2 = Codex enable, Phase 3 = Mistral
enable), conflicting with the new README phase plan rewritten by D43-A
where Phase 2 means multi-key auth.

Reviewer's recommended minimal fix (B1): add a clarifying note in
ALIGNMENT.md § Provider Inventory header explaining the dual usage,
rather than amend the tables or audit trigger wording. This keeps D43-A
within "pure doc cleanup" scope.

- ALIGNMENT.md § Provider Inventory: one-paragraph "Note on phase
  terminology" inserted between the v0.1 zero-Enabled-Providers
  rationale and the Enabled Providers table. No Speculative-Candidate
  table change, no audit-trigger wording change, no governance-text
  change.
- CHANGELOG.md Unreleased D43-A entry: ALIGNMENT.md added to the file
  list with a one-line explanation referencing the reviewer-P2 fold-in.

Test count: 468 → 468 (npm test verified locally after fold-in; no test
file touched).

Authority: PR #18 fresh-context reviewer finding P2; CLAUDE.md release_kit
overlay phase_rolling_mode — under Unreleased.
