Jiayuan Zhang e9dab0022e feat(github): PR card layout v3 increment — stats + segmented progress bar
Replaces the row + badge layout under "Pull requests" on the issue
detail sidebar with a card that mirrors the GitHub PR summary look:
title, author/avatar, +N −M · K files diff stats, segmented progress
bar (failed → pending → passed, failure leftmost), and a one-line
status caption following an explicit priority pass-through.

Backend
- Migration 092: github_pull_request adds additions / deletions /
  changed_files (INT NOT NULL DEFAULT 0). Zero defaults are what the
  new frontend treats as "legacy backend — hide the stats row" so old
  PR rows that pre-date this migration don't render "+0 −0 · 0 files".
- pull_request webhook handler reads stats off the top-level payload.
- ListPullRequestsByIssue now surfaces per-suite counts
  (checks_passed / failed / pending) alongside the existing aggregate
  conclusion, so the segmented bar reuses the already-computed counts
  with no new aggregation.

Frontend (packages)
- core/github/pull-request-status.{ts,test.ts}: pure-function module
  for the status-kind priority table and the segment derivation; 15
  cases covered, includes the "all-zero → hide stats" guard.
- views/issues/components/pull-request-list.tsx: PullRequestCard plus
  a compact-row fallback used when count > 4 (first 3 as cards, the
  remainder collapsed behind a Show more toggle).
- i18n: new `pull_request_card_*` keys in en + zh-Hans.

Tests
- 12 component tests covering each rule of the priority table, the
  legacy-zero stats fallback, and the collapse threshold.
- Reuse of the v3 webhook handler tests confirmed.

Verification
- pnpm typecheck + pnpm test green (60 test files, 536 tests).
- go build ./... + go vet ./... clean.
- 6 demo issues (DEV-2..DEV-7) screenshotted via Playwright; see the
  PR comments for the visual check matrix.

-- PR diff stats (additions / deletions / changed_files) for the card layout.
-- Source: top-level `pull_request` object on every pull_request webhook event
-- (opened / synchronize / edited / labeled / ...). NOT NULL DEFAULT 0 means
-- legacy rows that pre-date this migration read as zero, which the frontend
-- detects via `total === 0` and hides the entire stats row — so the card never
-- renders a misleading "+0 0 · 0 files" caption for rows that just haven't
-- been refreshed by a webhook yet.
