Update Claude and Codex orchestrator workflows

[JJ27]

Builds on the agent-specific skill support merged in #1076.

What did you change, and why?

Update the Claude and Codex Smart Router Orchestrator instructions with separate workflows for task ownership, focused evidence gathering, and independent parallel assignments.

• Claude keeps connected investigations in the root when delegation would repeat the work. A delegated owner handles discovery, implementation, checks, and an integration-ready result.
• Codex chooses the final-answer owner before delegation. For delegated read-only investigations that the root will present, one child acquires the complete cited evidence and the root synthesizes it. Implementation owners retain the full edit, test, and fix loop.

Preserve the supplied workflows, role scopes, and execution safeguards. Keep the UG name, full activation and on/off guidance, and runtime model-evidence requirement. Adapt native Claude role names and references to the standalone plugin's unbundled configuration helper. Claude keeps its Sonnet role defaults. Codex requests Luna without forcing a reasoning effort, allowing a routed model to use its supported default. This avoids a rejected spawn when the routed model does not support max. One restricted fallback attempt remains for rejected bundled defaults; UG routing can replace the requested model. Explicit user and policy constraints still apply.

When a harness truncates the hook output, both skills direct it to read the full agent-specific file before proceeding.

Changes are limited to the two skill instruction files and their README. Both skill files use version 1.2.0.

How do you know it works?

• 33 focused tests passed across test_skills.py and test_codex_routing.py, covering installation, agent-specific hook content, and routing.
• Compared each file directly with its supplied source: the original delegation rules, role scopes, coordination instructions, and integration/verification text are preserved with the agreed UG adaptations; UG's runtime-evidence guidance is appended. Codex's recovery conditions and single retry are retained, replacing only the helper-generated eligibility value with a written rule.
• YAML/entrypoint checks, the standard Ruff lint/format and type-check gate, and diff checks passed.

The truncated-hook recovery still needs live CI verification. Live-agent quality, cost, and latency have not been evaluated.
