Add CrowdStrike logo, Codex/Copilot CLI sections, and broaden pre-flight check (#6)

Add the standard CrowdStrike Falcon logo to the top of the README. Add Codex
and Copilot CLI setup sections using ~/.agents/skills/ symlink discovery
(sourced from official docs). Reorder tool sections alphabetically. Broaden the
A/B test pre-flight check to compare all plugin directories instead of a single
canary file.
