Summary: This PR restructures AGENTS.md to follow the avoidwork template format with numbered sections and consistent headings.

Changes:

• Replaces the prior free-form layout with an 8-section hierarchy (Core Rules → Checklist).
• Adds a new “Document Conventions” section describing how agents should update the file.
• Moves project overview, structure, and commands into “Project Context” with an expected layout block.
• Introduces a quick-commands table for common npm tasks.
• Groups style/tooling and testing expectations under “Code Conventions”.
• Organizes the public API notes into an “API Conventions” section.
• Adds explicit Git conventions (Conventional Commits + branching + review expectations).
• Moves operational guidance (coverage + common pitfalls + workflow) into a dedicated section.
• Creates “Session Learnings” and a pre-TODO-completion checklist for repeatable review hygiene.

Technical Notes: This is a documentation-only change intended to standardize agent guidance without altering runtime code.
