[codex] add native claude remote control harness

[waitdeadai]

What changed

• Adds a native Claude Code Remote Control route for /remote-control, /rc, claude --remote-control, and claude remote-control.
• Removes Remote Control blocker env vars from shared/project example profiles and profile repair scripts.
• Adds remote-control-doctor and remote-control-smoke with green/red fixtures and static harness eval registration.
• Regenerates the harness capability map and updates README/CLAUDE/AGENTS/startup/test surfaces for 36 skills.

Why

Claude Code has native Remote Control, but the harness was setting CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1, which Claude Remote Control troubleshooting identifies as an eligibility blocker. This keeps the feature native-only instead of adding a custom network control plane.

Validation

• bash scripts/remote-control-doctor.sh --static --json
• bash scripts/remote-control-smoke.sh --fixtures
• bash scripts/harness-capability-map.sh --check --json
• bash scripts/harness-eval.sh --json
• env HARNESS_STATIC_CI=1 bash scripts/test-harness.sh
• bash scripts/security-smoke.sh
• bash scripts/visualize-smoke.sh
• bash scripts/release-check.sh --static-only
• git diff --check

Runtime note

This PR proves static harness compatibility only. A live browser/mobile Remote Control connection still depends on the operator Claude account, org policy, login state, and network access.
