Merge sessions/sdlc/3b6c6c3e into main

Resolved conflicts:
- analysis/memory.md: kept condensed documentation from incoming branch
- crates/g3-core/src/skills/embedded.rs: removed unused HashMap import, kept better doc comment

Additional fix:
- crates/g3-core/src/prompts.rs: updated test to match current prompt file content
