v1.91.307.0 ship: proportional review depth (light, standard, full) with depth-checked receipts (#3567)

* feat(ship-receipt): carry across regenerated outputs and onto a reviewed tree after a rebase

A base merge whose only product-side change is a registered output the
pregate regen check proved fresh now carries the receipt. A rebased head
carries when its tree is one the receipt covers and its product patch-id
against the current base matches (RECEIPT_CARRY_TREE_MISMATCH otherwise).
Docs: merge main into a reviewed branch, never rebase it.

* fix: carry sets aside only outputs the regen check proved it recreates

The regen check deletes each touched output in its scratch worktree before
the command runs and records the ones recreated byte-identically as proven.
gstack-ship-receipt carry exempts only those paths, and only when the check
ran origin/<base>'s registry at the commit the carry reads. A file under an
output glob that the generator never writes stays product (pre-landing
review, #3564 pass 1).

* feat(ship-receipt): record review depth, check it in the queue, structured review-loop exception (#3559)

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* fix: prove generated outputs in a second regen run; literal names only

The regen verdict comes from the unmodified run again, so a generator that
reads its own registered output (gen-skill-docs and
qa/templates/functional-report-template.md) passes as before; the proof is a
second run with the touched outputs deleted, and its failure only means not
proven. The carry ignores a proven path with glob syntax, since it uses the
paths as pathspec globs (pre-landing review, #3564 pass 2).

* fix: pre-landing review fixes (depth scan binding, queue scope, carry checks)

- carry refuses a --head other than the checked-out HEAD, a receipt with
  gstack_version but no review_depth, and an owner exception that no longer
  stands; a dirty or foreign checkout makes the write-time gate scan
  unavailable (full)
- the queue binds a gate scan only to the full bound commit and recomputes
  the scope signals with gstack-diff-scope <base> --head <sha>, the same
  range the writer uses
- the queue checks the review-loop exception's fix-check ancestry
- a package.json version line counts as stamp-only only when it is a bare
  version key
- docs and help name what review_depth is and which registry the queue reads
