eas simulator canonical; waitlist link for non-access accounts

🎉 New features

• [eas-build-job] Replace eas-cli npm dist-tags with cli-versions.json. (#4147 by @douglowder)
• [eas-cli] Make eas simulator the canonical command and keep eas simulator:start as an alias. (#4112 by @szdziedzic)
• [eas-cli] Validate local composite functions referenced from workflow job hooks during eas workflow:validate. (#4064 by @sswrk)
• [eas-cli] Add eas sim as a shortcut for eas simulator commands, e.g. eas sim:list runs eas simulator:list. (#4150 by @szdziedzic)

🐛 Bug fixes

• [eas-cli] Point accounts without EAS Simulator access at the waitlist: eas simulator:availability includes the link (and a waitlistUrl field in --json), and eas simulator now fails early with the same message instead of a generic permission error. (#4151 by @szdziedzic)
• [build-tools] Revert "Pin the default agent-device version for remote sessions" now that agent-device 0.20.5 fixes the broken release. (#4144 by @gwdp)

🧹 Chores

• [reviewer] Migrate AI code reviews from GPT to Claude models on the claude-code engine (Sonnet 5 by default, Opus 5 for the security agent). (#4148 by @brentvatne)
