chore: remove upstream contributor metadata that the v1.4.0 merge dragged in

The bridge merge accidentally pulled in upstream contributor-management
files that don't apply to our fork. Most importantly,
.github/TEAM_MEMBERS got replaced with upstream's 15-name list, which
removed anandgupta42 + 28 other altimate maintainers — and the
pr-standards.yml workflow uses TEAM_MEMBERS to skip its
template/issue-link enforcement for team members. Result: every PR
from any altimate maintainer kept getting flagged with `needs:title` /
`needs:compliance` and auto-closed after 2 hours.

Restored from main (altimate-owned):
- .github/TEAM_MEMBERS — 30 altimate handles back in
- .github/pull_request_template.md — altimate's shorter template
  with the LLM-canary detector ("PINEAPPLE" trick)

Deleted (upstream-only, not relevant to us):
- .github/CODEOWNERS — references @adamdotdevin and packages we don't
  ship (`packages/app/`, `packages/tauri/`, `packages/desktop/`)
- .github/VOUCHED.td — upstream's contributor-vouching system
- STATS.md + script/stats.ts — upstream's GitHub-stars download
  tracker; we have our own analytics
- .zed/settings.json — upstream's Zed editor preferences leak
- .opencode/command/changelog.md — upstream's changelog command;
  we have our own bridge-merge / release process

skipFiles entries added to script/upstream/utils/config.ts so future
bridge merges drop these files before they hit the working tree:
- .github/CODEOWNERS
- .github/VOUCHED.td
- STATS.md
- script/stats.ts
- .zed/settings.json
- .opencode/command/changelog.md

Verification:
- `grep anandgupta42 .github/TEAM_MEMBERS` → present
- pr-standards.yml workflow's `getContent(path: '.github/TEAM_MEMBERS', ref: 'main')`
  will now resolve our restored list once this merges to main.
- 666 tests in test/upstream/ + test/branding/ still pass after the
  cleanup; 87 v140-merge-* tests still pass.
