Brandon ThomasandClaude Opus 5.5 3e323bfa2a Robustness: VectorCraft never crashes — no panics in shipped code
Shipped code no longer unwraps, expects or panics: every one of the 124
unwrap()/expect()/panic!/unreachable! sites outside tests now handles the
failure (Result/Option, ?, let-else, defaults) and reports errors to the user.

- Lints: workspace clippy denies unwrap_used, expect_used, panic, todo,
  unimplemented and unreachable; clippy.toml allows them in tests, and
  integration tests, examples and testkit opt out explicitly.
- Safety net (vectorcraft_engine::guard): a panic in a top-level command rolls
  the document back and returns EngineError::Internal; a panicking tool is
  reset; the MCP server answers with an internal error and keeps serving; the
  UI frame and each control request are guarded.
- APIs that hid failures now return them: Rendered::to_png/to_jpeg/to_webp
  return Result (JPEG/WebP errors used to write empty files),
  FontDb::face returns Option, Region::top returns Option.
- Fuzzing: engine/tests/import_fuzz.rs feeds garbage, hostile and mutated SVG
  and PDF through import → render → export (30k cases locally, no panics).
- Docs: AGENTS.md/CLAUDE.md rule, docs/development.md "Robustness" section,
  README pointer and a PR template checklist.

What and why

How it was tested

Checklist

  • cargo xtask ci passes (fmt, clippy, tests, assets, layers, wasm).
  • No panics in shipped code: no unwrap(), expect(), panic!, unreachable!, todo! or unimplemented! outside tests, and no unchecked indexing on data from files, parameters or messages. Errors are returned as Result and shown to the user (why and how).
  • Clean-room: nothing copied from Adobe products or GPL/AGPL code (AGENTS.md).
  • Every new asset has a row in ASSETS.md.
