- Use `<!-- bot: {id} -->` header format instead of `<!-- sticky-job: -->`
- Add extractBotHeader() for cleaner header extraction
- Move header preservation to MCP server instead of modifying sanitizer
- Adopt regex-based matching with hasAnyHeader check and legacy fallback
- Use context.inputs.botId for dynamic bot ID matching
- Revert sanitizer.ts to keep security code untouched
