PR Review: Add bot_author checks to skip ETR automation for bot PRs

Code Quality Assessment: ✅ APPROVE

Positive aspects:

• Consistent implementation of bot_author condition across all relevant automations
• Good reuse of the is.bot_author expression following DRY principles
• Clear intent - effectively excludes bot PRs from ETR automation
• Uses appropriate regex patterns for common bot naming conventions

Potential improvements:

• Consider expanding bot detection patterns to include renovate, greenkeeper, etc.
• The is.bot_author definition is repeated 4 times - could add documentation note about shared conditions

Assessment summary:

• No security risks - only affects automation triggers
• Efficient implementation using short-circuiting some filter
• No performance concerns
• Documentation-only change, no unit tests required
• Low risk, high value improvement

This change effectively prevents ETR automation from running on bot PRs, improving both resource utilization and workflow clarity.

Rating: ✅ APPROVED - Clean implementation following gitStream best practices.
