🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Update the main-dispatch capacity guidance.

This row says main dispatch can place the Claude wrapper and remote daemon on owned runners. The explanation at Lines 236–240 still says those lanes are not counted and describes only nine machines. The new Release row adds another possible side lane. State that main can require nine root runners plus its selected side lanes, so operators can size CI_OWNED_MAIN_RESERVE against the actual plan.

Review comment at @docs/ci-runners.md at line 757:
Update the main-dispatch capacity guidance for the `ci.yml` `claude-wrapper` and
`remote-daemon.yml` macOS test lanes to state that main may need nine root
runners plus its selected side lanes, including the possible Release side lane.
Explain that operators should size `CI_OWNED_MAIN_RESERVE` against the actual
plan.
