Issue Title: Developer Experience AI Acceleration

1. Local Development Automation

• Setup Scripts: Set up cd aliases and worktree aliases
• Git Hooks: Implement pre-commit hook to enforce cargo fmt.
• Linter Configuration: Add clippy.toml to enforce project-specific lints (e.g., clippy::perf, clippy::unwrap_used).
• Architecture Summary: Create docs/ARCHITECTURE_SUMMARY.md as a high-density context file for AI agents (diagrams, key types, data flow).
• AI Command Templates: Add structured prompts in .gemini/commands/ (Maybe commit? not sure):
  • Generate-Test.toml: Scaffold tests using test_utils.
  • SQLite-Research.toml: Context gathering helper.
• Rule Refinement: Update .gemini/GEMINI.md and/or .cursorrules with specific "Negative Constraints" (what not to do) and preferred code patterns.

2. Git History Transparency

• Attribution Standards: I want some way of having AI code identified as the author in the git history so that we can differentiate it.
