chore: update tooling, deps, and cloudflared test matrix

[JacobLinCool]

Summary

• Bump pnpm 9.6.0 → 10.33.2; allowlist esbuild build script via pnpm.onlyBuiltDependencies
• Refresh devDependencies to latest, including major bumps: eslint 9→10, typescript 5→6, vitest 2→4, @types/node 22→25, typedoc 0.26→0.28
• Update tsconfig.json for TypeScript 6: add types: ["node"] (TS 6 + @types/node 25 no longer auto-load by default), set moduleResolution: "node10", set ignoreDeprecations: "6.0"
• Refresh test matrix in .github/workflows/test.yml to span recent cloudflared versions: latest, 2026.1.2, 2025.11.1, 2025.9.1, 2025.7.0

No runtime/library code changed; this is dev-tooling only.

Test plan

• pnpm install (clean)
• pnpm build (CJS + DTS)
• pnpm lint (only pre-existing warnings)
• pnpm test locally — passes
• CI matrix passes across OS × cloudflared versions
