* 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.

* 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

* ui: bake jpeg exif orientation into uploaded images
stb_image in mtmd ignores exif metadata, so rotated smartphone photos
reach the model with raw pixel orientation. The webui now reads the
exif orientation tag at send time and feeds it into the existing
capImageDataURLSize canvas pass: the browser applies the rotation when
decoding, so capped images come out upright for free, and images under
the cap threshold get a single plain redraw when orientation > 1.
At most one re-encode ever happens per image. Upright jpegs with
capping disabled pass through untouched, bit perfect.
Adds jpeg-orientation.ts with a minimal exif parser working on a
bounded base64 prefix (both endianness, returns 1 on any malformed
input) and unit tests against handcrafted jpeg byte streams.
* ui: move jpeg exif constants into lib/constants
* ui: add browser test for jpeg orientation and capping
Covers capImageDataURLSize end to end in chromium with real Pillow
generated jpeg fixtures across exif orientations 1/3/5/6/8: upright
quadrant colors checked pixel-wise, expected dimensions with and
without capping, no orientation tag left in the output, and strict
passthrough when nothing needs rewriting.
