fix(ci): improve CocoaPods install resilience against CDN rate limiting

Remove the standalone `pod repo remove trunk` step that runs before
every `pod install`. On ephemeral Cirrus runners the only source of
trunk specs is the actions/cache restore — deleting them forces a full
CDN re-download (thousands of HTTP requests) on every run, increasing
the surface area for 429 rate-limit errors.

Move trunk removal into `on_retry_command` so cached specs are used for
an incremental `--repo-update` on the first attempt (low CDN load), and
only cleared on failure for a clean retry.

Additional improvements:
- Increase max_attempts from 2 to 3 (matches other retry steps)
- Increase retry_wait_seconds from 30 to 60 (longer backoff for CDN 429)
- Add ::warning:: annotation on retry for visibility in Actions UI
- Add COCOAPODS_DISABLE_STATS=true to skip analytics during CI
