Summary

• Bump MetaLens to 0.2.5 for dependency maintenance and security updates.
• Update Electron to 43.2.0 and frontend dependencies, including React/React DOM 19.2.8.
• Update transitive Electron tooling dependency fast-uri to 3.1.4 for upstream security fixes.

Validation

• Local: npm --prefix frontend run build
• Local: python\.venv\Scripts\python.exe -m pytest python/tests/ -v (47 passed, 1 skipped)
• Local: npm --prefix electron exec electron -- --version -> v43.2.0
• GitHub Actions on develop: Build & Release passed, CodeQL passed
• Beta release created: v0.2.5-beta.1

Notes

• npm audit for frontend reports 0 vulnerabilities.
• npm audit for electron still reports existing Electron Forge/tooling-chain advisories around tar/tmp/brace-expansion; npm reports no fix available for part of that chain, so this PR keeps the dependency update scoped.
