Externalize agent prompts into versioned template files

[Flamki]

Problem

Prompt text is currently embedded in code, making iteration and review harder.

Scope

• Move prompts to dedicated files under src/prompts/
• Add light templating for runtime variables
• Track prompt versions/changelog

Acceptance Criteria

• Prompt updates do not require touching core service logic
• Prompt files are testable and reviewed like content assets
• Rollback path for prompt regressions is documented

Hi, maintainer. I would move the prompts out of the main codebase into separate files under src/prompts/ so they can be updated without changing the core logic. I would also add a simple templating setup for runtime values, organize the prompts with versions and a changelog for easier tracking, and make sure they can be tested independently like other content files. Finally, I would document a rollback process so older prompt versions can be restored easily if any update causes issues.
I would appreciate if i can work on this.
