v4.0.0 - Knowledge-first workflow

Highlights

• Re-centers the template on a vendor-neutral, repository-owned project knowledge network.
• Routes work as Direct, Tracked, or Governed without a mandatory document chain.
• Uses one stable WORK record for tracked and governed tasks, including governed decisions, approvals, evidence, and rollback gates.
• Promotes durable experience into rules, linked notes, runbooks, or on-demand project Skills.
• Supports parallel task branches and worktrees while keeping companion helpers optional.
• Adds an opt-in, privacy-reviewed feedback path for improving the upstream template.

Breaking changes

• This release is a new-project template and does not provide migration or compatibility behavior for previous layouts.
• Removes numbered zettelkasten directories and independent REQ, TECH, PLAN, and REVIEW workflow artifacts.
• Flattens durable knowledge entry points and upgrades the payload marker to canonical-payload-v4.

Validation

• Full distribution lifecycle validation passes, including tool-free initialization, single-WORK routing, governed gate enforcement, knowledge links, project Skills, optional helpers, and worktree isolation.
• Official Agent Skill validation passes.
