## Summary
Add deterministic mock data fixtures for browser tests so they can use
`page.route()` to intercept API calls without depending on a live
backend.
## Changes
- **`browser_tests/fixtures/data/nodeDefinitions.ts`** — Mock
`ComfyNodeDef` objects for KSampler, CheckpointLoaderSimple, and
CLIPTextEncode
- **`browser_tests/fixtures/data/systemStats.ts`** — Mock `SystemStats`
with realistic RTX 4090 GPU info
- **`browser_tests/fixtures/data/README.md`** — Usage guide for
`page.route()` interception
All fixtures are typed against the Zod schemas in `src/schemas/` and
pass `pnpm typecheck:browser`.

Upgrades `pnpm/action-setup` from v4.2.0 to v4.4.0 across all 16
workflow files and the shared `setup-frontend` action.
## Why
GitHub Actions will force Node.js 24 as the default starting June 2,
2026. The v4.2.0 pin ran on Node.js 20 and emitted deprecation warnings
on every CI run. v4.4.0 was released specifically to address this,
updating the action runtime to Node.js 24.
- Fixes the warning: *"pnpm/action-setup@41ff72... Actions will be
forced to run with Node.js 24 by default starting June 2nd, 2026"*

## Summary
Standardize the repo's Node contract on 24 while centralizing workflow
resolution through `.nvmrc` so local setup, CI, and package metadata
stay aligned from one version file.
## Changes
- **What**: Add `package.json` `engines.node = 24.x`, switch every
`actions/setup-node` workflow in the repo to `node-version-file:
'.nvmrc'`, and update contributor and Playwright docs to point to
`.nvmrc` as the Node source of truth.
## Review Focus
The workflow behavior should be unchanged apart from sourcing the Node
version from `.nvmrc` instead of repeating literals like `20`, `22`,
`24.x`, or `lts/*`. GitHub's formatter also moved the new `engines`
block to the package metadata section near the end of `package.json`.

Add PostHog as a telemetry provider for cloud builds so custom events
can be correlated with session recordings. Follows the same pattern as
MixpanelTelemetryProvider with dynamic import, event queuing, and
disabled events from remote config. Tree-shaken away in OSS builds.
The posthog-js package uses Apache-2.0 (verified from its LICENSE file)
but declares it as "SEE LICENSE IN LICENSE" in package.json, which
the license checker can't parse.

## Summary
Adds CI workflow to validate OSS build compliance by checking for
proprietary fonts and non-approved dependency licenses.
## Context
- Part of comprehensive OSS compliance effort (split from closed PR
#6777)
- Uses simple bash/grep approach following proven #8623 pattern
- Complements telemetry checking in PR #8826 and existing #8354
## Implementation
### Font Validation
- Scans dist/ for proprietary ABCROM fonts (.woff, .woff2, .ttf, .otf)
- Fails if any ABCROM fonts found in OSS builds
- Provides clear fix instructions
### License Validation
- Uses `license-checker` npm package
- Validates all production dependencies
- Only allows OSI-approved licenses:
- MIT, Apache-2.0, BSD-2-Clause, BSD-3-Clause, ISC
- 0BSD, BlueOak-1.0.0, Python-2.0, CC0-1.0
- Unlicense, CC-BY-4.0, CC-BY-3.0
- Common dual-license combinations
### Workflow Details
- Two separate jobs for parallel execution
- Runs on PRs and pushes to main/dev
- Builds with `DISTRIBUTION=localhost` for OSS mode
- Clear error messages with remediation steps
## Testing
- [ ] Font check passes on current main (no ABCROM fonts in dist)
- [ ] License check passes on current main (all approved licenses)
- [ ] Intentional violation testing
## Related
- Supersedes remaining parts of closed PR #6777
- Complements PR #8826 (Mixpanel telemetry)
- Follows pattern from PR #8623 (simple bash/grep)
