AgentXchain v2.63.0

v2.63.0 ships two new operator inspection surfaces — agentxchain role and agentxchain turn — plus Homebrew release-path hardening.

What Changed

• agentxchain role list and role show <role_id> provide dedicated read-only inspection of governed role definitions with --json support. Color-coded authority levels (green=authoritative, yellow=proposed, dim=review_only). Fails closed on ungoverned and legacy v3 repos.
• agentxchain turn show [turn_id] inspects active governed turn dispatch bundles — assignment, prompt, context, and manifest artifacts. Defaults to the single active turn. Supports --artifact <name> for raw artifact output and --json for structured metadata. Fails closed on no-active-turn, multi-active-without-id, and unknown artifacts.
• release-bump.sh now carries the Homebrew SHA deterministically from HEAD:cli/homebrew/agentxchain.rb instead of trusting the working tree. Hand-edited target-version SHAs are normalized back to the committed value.
• release-bump.sh success banner now explicitly reminds operators that the Homebrew mirror is in Phase 1 (stale SHA) until sync-homebrew.sh runs post-publish.

Why It Matters

Every major governed concept — templates, plugins, proposals, events, history — already had a dedicated CLI surface. Roles and active turn dispatch did not. Operators had to use config --get roles (raw JSON dump) or manually inspect .agentxchain/dispatch/turns/ files. These two commands close the operator-surface asymmetry so every governed concept is inspectable through first-party CLI commands.

Evidence

• 64 tests / 18 suites / 0 failures (combined role + turn + release-identity suite)
• Role proof: node --test cli/test/role-command.test.js (7 tests including AT-ROLE-007 legacy v3 rejection)
• Turn proof: node --test cli/test/turn-command.test.js (6 E2E subprocess tests)
• Docs proof: node --test cli/test/docs-cli-command-map-content.test.js cli/test/docs-turn-command-content.test.js (10 tests)
• cd website-v2 && npm run build -> clean production build
