fix(evolution): unblock analysis/implementation/integration stages by accepting GITHUB_TOKEN instead of requiring GITHUB_PRIVATE_TOKEN (#470)

The evolution analysis, implementation, and integration cron jobs were
configured to require GITHUB_PRIVATE_TOKEN, which is not set in the cron
environment. However, GITHUB_TOKEN IS set and the gh CLI is already
authenticated via persistent gh auth login.

Changes:
- Switch token_env from GITHUB_PRIVATE_TOKEN to GITHUB_TOKEN in all
  three cron yaml configs
- Update prompt instructions to verify gh CLI auth first, falling back
  to GITHUB_TOKEN
- Update all three SKILL.md files (security sections, operating mode,
  frontmatter mode field, description)
- Change mode from PRIVATE to PUBLIC since the auth mechanism is now
  the standard GITHUB_TOKEN / gh CLI path
