v0.22.0 — any agent in any role, with measured orchestrator capability

Added

• Any agent can be offered for any role. The registry's roles array no longer gates the pickers. Every detected agent appears for orchestrator, coder, reviewer, scout and integrator; roles is kept and documented as informational so existing readers keep working.
• Orchestrator capability is MEASURED, not declared. og now probes Omnigent's own harness capabilities (capabilities[<harness>].subagents) to decide whether an agent can actually dispatch sub-agents, caching the result and falling back to the registry relay flag when Omnigent is not importable from the installer's interpreter. Every message says which source answered. An acp:<slug> harness resolves through the shared acp key first.
• The capability list is visible. ./install.sh --check prints an orchestrator-capability block, and --questions carries a structured per-agent dispatch map ({can, source}) on the orchestrator question alongside the existing human-readable note — so an AI installer never has to parse prose to learn whether an agent can orchestrate.
• Delegated worker tabs carry the vendor glyph. In og herdr, a worker's tab read coder_cmdcode:fix-stale-comments, repeating the agent name already drawn as a mark in og agents. It now reads ⌘ fix-stale-comments, resolved through the same chain the pane uses so a tab and its row can never disagree about a worker's brand.

Fixed

• Six registry rows claimed a dispatch capability they do not have. agy, cursor, gemini, goose, hermes and grok were all marked relay: true while their harness reports subagents=False. grok was additionally offered as an orchestrator, so the installer would happily have built a brain that could never delegate — and nothing would have said so until the first real dispatch.
• devin pointed at a harness id that has no capability entry at all (devin rather than devin-native), so the preflight map would have dropped the worker. Repointed; devin-native measures subagents=True, and the row stays flagged unverified_roles: ["orchestrator"] until a real run proves it.
• A refusal now names the fix in the same sentence as the fault:
  cmdcode cannot be the orchestrator: omnigent reports harness 'acp:command-code' (via shared key 'acp') cannot dispatch sub-agents, so it could never delegate. Orchestrator-capable agents here: claude, opencode, codex, devin.

Changed

• Former hard refusals for non-orchestrator roles are now warnings. An unverified row or an unknown prompt_delivery warns and proceeds — the first real dispatch is the proof, so neither may block an otherwise-legal install.

Docs

• AGENTS.md and the registry header now describe roles as informational and relay as a fallback used only when the measured probe is unavailable.
