feat: adopt The Professor persona with Groq streaming and Radio Comms UI

[Yuva-Deekshitha-N]

Description:

Adopts "The Professor" persona for the AI inference layer. Updates system and user prompts to use cold, precise radio-comm style framing where every fix is an "adjustment to the plan." Implements Groq streaming (stream: true) for ultra-fast, low-latency responses. Renames the UI chat interface from "AI Security Explanation" to "Radio Comms." Also adds prompt injection sanitization on user-controlled inputs before LLM interpolation.

Type of Change:

• New feature
• Bug fix
• Documentation update
• Refactoring
• Performance improvement

Testing:

• Opened a test PR on a linked repository to trigger the webhook scan
• Verified Radio Comms label appears in the findings dashboard
• Confirmed The Professor's tone in AI-generated explanations and remediation steps
• Verified Groq streaming assembles responses chunk-by-chunk via for await
• Confirmed prompt injection sanitization strips malicious patterns from code snippets

• My code follows the project's style guidelines
• I have performed a self-review of my code
• I have added tests that prove my fix/feature works
• My commits follow the Conventional Commits format

Additional Notes:

• sanitizeForPrompt() neutralizes code fences, strips injection phrases, and enforces a 2000 char limit on all user-controlled fields (description, fileLocation, codeSnippet) before LLM interpolation
• Groq model used: llama-3.1-8b-instant
