fix(qa): load ANTHROPIC_AUTH_TOKEN as ANTHROPIC_API_KEY for interactive E2E (#2894)

* chore: update agent GitHub star counts

* fix(qa): load ANTHROPIC_AUTH_TOKEN as ANTHROPIC_API_KEY for interactive E2E

QA VMs store the Anthropic key as ANTHROPIC_AUTH_TOKEN in
/etc/spawn-qa-auth.env, but the e2e-interactive handler only looked for
ANTHROPIC_API_KEY — causing the 6am cron to fail immediately with
"ANTHROPIC_API_KEY not set". Accept either name when loading from the
auth env file.

* fix(e2e): bump interactive harness timeout to 20min, fix zombie VM teardown

- SESSION_TIMEOUT_MS: 10min → 20min — provisioning a VM takes 3-4 min
  before onboarding even starts; 10min wasn't enough headroom
- interactive.sh: call cloud_provision_verify even on harness failure so
  teardown can find and delete any VM that was partially created (e.g.
  on timeout mid-provision) — previously left zombie VMs with no .meta file
