What this sync releases

Source plans are supplied explicitly, never discovered

Boatstack no longer scans directories for source plans, so it never retains context for work that was never shipped.

• auto-plan requires the plan produced in the host conversation to be passed explicitly with --plan <path>; the .product-loop/intake/ staging area and the .cursor/plans, .claude/plans, and .codex/plans scan roots are removed.
• A saved plan-mode file left in the repository can no longer become ambient context or block next-status with an ambiguity stop; with no started feature the state is simply NOT_STARTED pointing to auto-plan.
• The --plan path must be a durable in-repo file. A path outside the repository is rejected up front, because source_plan_path is hashed into the plan fingerprint and re-checked through build, and an out-of-repo file cannot stay committed and hash-current.
• The source_plan_path and source_plan_sha256 invariant is unchanged: the plan must still be a real, present, hash-current file from auto-plan through build.
