v0.6.2 — Multi-agent registry, identity checks, Codex/Claude cache path fixes

What's new in v0.6.2

Multi-agent registration

Second and later o2b init --agent-name <name> runs now append under ## Registered agents in AI Wiki/identity/agents.md instead of being a silent no-op. Idempotent for already-registered names — multi-runtime installs grow the registry incrementally.

Identity-aware install workflow

All branches (A–D) in install.md now require the installer agent to:

• Check config.yaml, agents.md, and Daily/*.md for a previously-set identity before asking the user.
• Surface the found name with a reuse-or-change question.
• Only offer defaults when no prior identity exists.

Verification — identity registry block

New section in install.md after vault init: confirms the chosen agent name appears in <vault>/AI Wiki/identity/agents.md. Treats a missing entry as an incomplete install.

Shared CLI symlink

New prelude note documents that o2b on PATH is a single shared symlink across runtimes. First install-cli wins; subsequent runs refuse to overwrite (by design).

Version pinning clarification

Replaced ambiguous "tracks main" wording with explicit "latest released version" guidance plus a concrete v0.6.1 vs v0.6.0 example.

Codex CLI cache path fix

Branch C steps 2–3 updated: Codex 0.129+ caches under ~/.codex/.tmp/marketplaces/<name>/, not the previously documented ~/.codex/plugins/cache/<marketplace>/<plugin>/<hash>/. Step 3 now uses a find pattern that works on either layout.

Claude Code cache path fix

Branch D step 3: Claude caches under a <version> segment (~/.claude/plugins/cache/<marketplace>/<plugin>/<version>/scripts/o2b). Same find-based fix as Branch C.

Tests

• Multi-agent registration test: verifies append order, section integrity, and idempotency for re-registration.
