Redesign agents-workflow for low-token projects

[Gusitir]

Summary

• redesign the canonical skill around eight explicit jobs and Lean/Standard/Strict assurance
• align templates, example, installers, hook, public documentation, versioning, and CI
• add RED/GREEN evaluations plus portable contract and installer tests

Why

The previous workflow mixed lifecycle responsibilities, required excessive model auditing, and contained contradictory or stale rules. Version 2 makes the default path practical for basic AI subscriptions while preserving risk-scaled review.

Impact

Existing projects migrate through MAINTAIN instead of INIT. Human documentation becomes an on-demand DOCUMENTATION.md snapshot. Local Git remains required; a remote is optional.

Validation

• 20 Python unittest cases pass
• PowerShell installer parser passes
• Git Bash syntax checks pass for installer and hook
• installers tested with paths containing spaces and malformed markers
• independent GREEN evaluations cover MAINTAIN, EXPORT DOCUMENTATION, and Lean assurance
