test: skip the mouse-safety suite when the addon does not load

 - Run (after `npm ci`): `npm run build:libghostty && npm run build:native && npm test`
 - Every native test skips when the addon does not load (`test/native-support.ts:nativeSupport`), so check the test output for skips.
 - `mise run ci-ubsan` builds the addon with UBSan (Linux, GCC), then runs the tests and smoke. Undefined behavior aborts the run. The task also fails when the addon's object files contain no UBSan checks, which means the flags did not reach g++ (`mise.toml:tasks.ci-ubsan`).
-- `test/workers.test.ts` checks the per-environment state in child processes with `worker_threads`. `test/terminal.test.ts` covers `feed`, `snapshot`, `resize`, `dispose`, the `RangeError` cases of the `createTerminal` checks in the addon, the `encodeMouse` bytes of each mouse format, `cursorVisible`, and the cell style fields. `test/mouse-safety.test.ts` runs the `encodeMouse` limits and the getter re-entry cases against both the package API and the raw addon object. It does not skip when the addon is missing. Its child-process cases load `src/` through `tsx`, so they need no `dist/` build. No vitest test covers `formatPlain`, `formatHtml`, `includeScrollback`, or the typed-array errors.

 - For changes to `TerminalWrap` or `InitAll`, also run the TLA+ lifecycle model: [`.agents/skills/verify-native-lifecycle/SKILL.md`](https://github.com/coder/libghostty-vt-node/blob/main/.agents/skills/verify-native-lifecycle/SKILL.md).
