Resolve the actionable Dependabot alerts via pnpm overrides (for transitive deps) and a Python pin bump.
- pnpm overrides: esbuild >=0.28.1 (the lone high-severity alert), @babel/core >=7.29.6, @opentelemetry/core >=2.8.0, js-yaml >=4.2.0, qs >=6.15.2, uuid >=11.1.1, yaml >=2.8.3
- rembg 2.0.62 -> 2.0.75 in requirements.txt and requirements-gpu.txt
Verified: pnpm install, typecheck, lint, and full build all pass.
NOT included: the astro advisory requires Astro 5 -> 6 (a major, breaking framework upgrade), which warrants its own migration PR rather than a security bump.
