feat: port competitor features, real-time SSE, and roadmap enhancements

[Patel230]

Summary

This PR ports and implements advanced competitor memory engine features and completes all roadmap items in Yaad:

• Skill Node Type & Parameterized Procedural Memory: Dynamic parameter templates & step validation ().
• Auto-Capture Hooks: Git pre-commit/post-merge & bash execution observation logging (, ).
• Cognitive Forgetting Curves: Ebbinghaus memory stability formula ((t) = e^{-t / S}$) integrated into decay routines (, ).
• Causal Relation Extractor: Automated and extraction ().
• Real-Time Event Streaming: Added SSE streaming endpoint ().
• Team Namespacing & Multi-Project Linking: Scoped team sharing & cross-project memory graph links ().
• Integration Documentation: Created integration guides for Gemini CLI () and OpenCode ().

Verification

• All 37 Go packages pass unit and integration tests (go test ./... -count=1 -timeout=120s
