rankaiyx 61328e6a91 feat(ui): add symbolic math support to JS sandbox via nerdamer (#25948)
* feat(ui): add symbolic math support to JS sandbox via nerdamer

Preload nerdamer (with decimal.js) in the sandboxed worker,
exposing the `nerdamer` global for symbolic computation:
simplify, expand, factor, diff, integrate, solve, laplace,
ilt, limit, partfrac, gcd/lcm, roots, coefficients, and more.

Mirrors the math.js integration pattern from the
feature/sandbox-symbolic-math branch, but uses nerdamer
for a lighter, more focused symbolic math engine.

* Update sandbox-harness.ts

* docs(ui): update sandbox tool description with detailed nerdamer usage guide

* Clarify nerdamer usage in sandbox tool description

Updated the description of the sandbox tool to clarify usage of nerdamer.

* ui: build nerdamer sandbox prelude from vendored source

Replace the vendored all.min.js with the readable nerdamer-prime
source and its two bundled deps (big-integer, decimal.js), licenses
included. A vite plugin bundles and minifies them at build time with
the upstream esbuild flags, exposed as virtual:nerdamer and imported
lazily on first sandbox use. The vendors package.json pins commonjs
so the project level type: module does not break esbuild format
detection. The harness gains a CSP removing network egress from the
worker, and browser tests cover the prelude, exact arithmetic, the
fetch block and the timeout.

Upstream snapshot: together-science/nerdamer-prime@1936145

* feat(ui): make symbolic math (nerdamer) a user-toggleable setting

- Add SYMBOLIC_MATH_ENABLED setting key and registry entry (checkbox, default false)
- Convert SANDBOX_TOOL_DEFINITION to buildSandboxToolDefinition(includeSymbolicMath)
  so the tool description includes/excludes nerdamer API docs dynamically
- Cache sandbox harness per variant ('nerdamer' / 'plain') for instant toggle
- Deprecate SANDBOX_TOOL_DEFINITION constant alias for backward compatibility
- Update tools store to pass symbolic math config into tool definition

* docs(ui): tell LLM to list nerdamer functions first, do not guess

* test(ui): enable symbolic math in sandbox tests via settingsStore config

* style(ui): fix formatting for tools.svelte.ts

Symbolic/numeric math via \`nerdamer\` (pre-loaded, do not require, use it directly).
