feat(config): add review.max_findings caps for blockers/nits (#2049)

[bohdansolovie]

Summary

• Add review.max_findings: { blockers?, nits? } to the focus manifest — non-negative integer display caps parsed with warn+ignore on invalid values
• Truncate rendered blockers/nits in the unified comment with a deterministic +N more footer; gate decisions are unchanged (display-only)
• When the whole object is absent, keep the legacy 12-item cap per list (byte-identical)

Fixes #2049

Test plan

• focus-manifest.test.ts — parse, round-trip, invalid warns, resolveReviewPromptOverrides
• max-findings-display.test.ts — truncate helper, renderer caps, gate-invariant, bridge wiring
• config-templates.test.ts — documents max_findings in example yml files
• npx tsc -p tsconfig.json --noEmit passes locally
• CI green (unit + codecov patch ≥99%)

Review summary
Adds `review.max_findings` display-only caps for blockers/nits in the unified comment: focus-manifest parsing (non-negative int per field, warn+ignore on invalid, byte-identical when absent via new EMPTY_MAX_FINDINGS_CONFIG), a pure `truncateDisplayedFindingLines` helper applied after the existing dedupe step, and wiring through resolveReviewPromptOverrides → processors.ts → unified-comment-bridge → renderUnifiedReviewComment. The legacy 12-item cap is preserved by treating `ctx.maxFindings === undefined` as LEGACY_FINDINGS_DISPLAY_CAP, and gate/blocker semantics are explicitly untouched (only rendered lists are truncated), which the test suite verifies directly (byte-identical legacy path, per-field null=uncapped, gate-invariant test). Test coverage is thorough (parse/round-trip/invalid warnings, truncate helper, renderer caps, bridge wiring, config-template docs).

Nits — 5 non-blocking

• src/review/unified-comment.ts: `dedupeLines`'s `cap` param lost its implicit default of 12 (now `cap?: number` with no default, since capping is applied later via `truncateDisplayedFindingLines`) — since the full file isn't visible here, confirm no other caller of `dedupeLines`/`bullets` in this file relied on the old implicit 12-item truncation, or it now silently renders unbounded lists.
• src/queue/processors.ts: `maxFindingsForReview` is only spread into the unified-comment branch's args (the `if` block around line 9502) — confirm the `else` branch using `buildPublicPrIntelligenceComment(commentArgs)` intentionally doesn't need the cap rather than silently dropping the feature on that code path.
• A cap of `0` still renders an empty 'Nits'/blockers section header with just a '+N more' footer (src/review/unified-comment.ts renderUnifiedReviewComment) — worth a one-line note on whether that's the intended UX for `max_findings: { nits: 0 }`.
• Add an explicit test asserting `buildPublicPrIntelligenceComment`'s behavior (or its exclusion) when `max_findings` is configured, to make the branch coverage in processors.ts explicit rather than implicit from the diff.
• Consider a short code comment at the `dedupeLines` cap-param call sites noting that truncation now happens downstream via `truncateDisplayedFindingLines`, to prevent a future edit from reintroducing double-capping.

Review context

• Author: bohdansolovie
• Role context: outside_contributor
• Public audience mode: oss maintainer
• Lane context: Repository registration is not available in the local Gittensory cache.
• Public profile languages: Python, C++, JavaScript
• Official Gittensor activity: 354 PR(s), 7 issue(s).
• PR-specific overlap: none found.

Contributor next steps

• Keep the PR focused and include validation evidence before maintainer review.

Signal definitions

• Related work = same linked issue, overlapping active PRs, or title/path similarity.
• Change scope = cached public metadata such as size labels, draft state, and review-burden hints.
• Validation posture = whether the PR provides enough public validation/test evidence for maintainer review.
• Contributor workload = public contributor activity and cleanup pressure, not a repo-wide quality failure.
• Contributor context = public GitHub/Gittensor identity context; non-Gittensor status is not a blocker.
