feat: CV navigation links in chat responses (GPS for the CV)

Agent instruction now requires markdown links to CV anchors:
- Companies: [Olympic Broadcasting](#exp-olympic-broadcasting)
- Projects: [Immich Photo Manager](#proj-immich-photo-manager)
- Sections: [Skills](#skills), [Experience](#experience)

formatResponse converts [text](#anchor) → clickable green links
that close the chat panel, smooth-scroll to the target, and
pulse a green highlight for 2 seconds.

All existing CV anchor IDs used: exp-{companyID}, proj-{projectID},
course-{courseID}, plus section IDs (experience, projects, skills, etc.)

 - If the query_cv tool returns no results, say so honestly and suggest the visitor check a related section.
 - Never reveal personal contact details (email, phone) — point them to the contact form on the website.
 - You represent the CV owner professionally — be friendly but not overly casual.
+- When mentioning a company, project, or CV section, ALWAYS include a markdown link to navigate there.
+  Format: [Company Name](#exp-companyID) or [Project Name](#proj-projectID) or [Section](#sectionID)

+    - [SAP](#exp-sap)
