feat(CW-7503): pre-existing defects are reported without blaming the author, and the tally is machine readable

Two mechanisms from the competitive research note
(docs/research/competitive-code-review-20261022.md), plus the negative result
that makes a review's silence meaningful.

**Authorship is decided mechanically, never by the model.** `introduced_lines`
computes the lines this change actually added from the diff, and
`apply_claim_limits` sets `authorship` on every claim from it. A model that
labels its own accusation "pre-existing" is overruled. Three cases:
- the anchor is an added line → `introduced`;
- the anchor is inside a hunk but not added (unchanged context) → `preexisting`,
  because the code was already there;
- no usable anchor → `preexisting`, because we cannot prove this change wrote
  it and an accusation we cannot support is worse than a label we can.

**A pre-existing defect cannot hold the merge risk up on its own.** If every
claim is pre-existing, the finding signal is zero and the level is set to low,
keeping the model's reason and prefixing why. Enforced inside
`apply_claim_limits`, the one place claims are adjudicated, so every caller
inherits it. Structural risk from triage is separate and untouched.

**Pre-existing claims are never inline comments.** `inline_issue_comments`
skips them, so the author is not handed an inline accusation for code they did
not write; the summary renderer gives them their own section, after the
findings this change introduced.

**`ruled_out`: the negative result.** What the reviewer checked and found
sound, one line each, capped at five, rendered under "Checked, nothing wrong".
Distinct from `verified` (what established a claim) and from `not_reviewed`
(what was not looked at). It never carries a claim and never affects merge risk.

**A machine-readable tally.** Every summary ends with
`<!-- codewhale-review: {"blocker":N,"concern":N,"nit":N,"introduced":N,"preexisting":N} -->`
— integers and closed enums only, asserted by a test that feeds paths and prose
through it and checks neither appears.

Also: `inline_anchorable` is recorded per claim, so a claim whose line is not in
the diff is marked rather than assumed — the publisher turns that into the body
fallback.

Schema compatibility: every new field is optional with a default; `ruled_out`
and `authorship` are absent from older receipts and read as empty and
`introduced`.

Checks: `scripts/dev-cargo.sh check -p codewhale-tui --lib` clean; rustfmt
clean on the changed files; `scripts/dev-cargo.sh test -p codewhale-tui --lib
tools::review` = 86 passed, 0 failed, including four new tests: authorship
decided from the diff while the model's own label is overruled; an unanchorable
claim kept and marked instead of dropped; pre-existing findings alone forcing
merge risk to low while the model's reason survives; and the summary's section
order plus a tally that parses as JSON and contains no path.

Not claimed: the corpus delta. #18's done-when includes behaviour on real pull
requests, and the model-backed corpus run is still blocked on an approved eval
route and budget (#1).
