Schedule live telemetry quality checks

[blove]

Summary

• add a scheduled/manual PostHog telemetry quality workflow using the live contract checker
• add critical-event coverage thresholds for install and runtime telemetry so zero recent samples become blocking findings
• ignore known PostHog attribution metadata in live payload warnings and document the thresholded check

Verification

• PATH=/tmp/codex-node-v24/bin:$PATH npx tsx --test tools/posthog/live-quality.spec.ts (red first for new coverage/metadata tests, then green)
• PATH=/tmp/codex-node-v24/bin:$PATH npx nx test posthog-tools --runInBand
• PATH=/tmp/codex-node-v24/bin:$PATH npx tsc -p tools/posthog/tsconfig.json --noEmit
• PATH=/tmp/codex-node-v24/bin:$PATH npx nx lint posthog-tools (passes with existing warnings in report/sync/generated types)
• PATH=/tmp/codex-node-v24/bin:$PATH npx prettier --check .github/workflows/posthog-quality.yml tools/posthog/README.md tools/posthog/live-quality.ts tools/posthog/live-quality.spec.ts && git diff --check
• set -a; source /Users/blove/repos/angular-agent-framework/.env; set +a; PATH=/tmp/codex-node-v24/bin:$PATH npx nx run posthog-tools:quality:live -- --days 7 --limit-per-event 25 (0 errors, 0 warnings)
• set -a; source /Users/blove/repos/angular-agent-framework/.env; set +a; PATH=/tmp/codex-node-v24/bin:$PATH npx nx run posthog-tools:quality:live -- --days 7 --limit-per-event 25 --require-critical-coverage (expected failure: zero recent samples for ngaf:runtime_request_created, ngaf:stream_started, ngaf:stream_ended)

Notes

• Set repository Actions secrets with gh secret set: POSTHOG_PERSONAL_API_KEY and POSTHOG_PROJECT_ID.
• npx actionlint .github/workflows/posthog-quality.yml could not run locally because npm could not determine an executable for that package in this environment.
