v0.3.0 — Audit fixes + type filter chip

Added

• In-menu type filter chip — when the catalog contains 2+ model types and the type prop is unset, a "Filter" chip appears next to the sort button. Click to narrow the list to one type. New props: typeFilter, onTypeFilterChange, showTypeFilter.
• Strict coercion helpers — toBool, toStr, toStrArray alongside toNum. Used internally to replace unsafe as casts throughout the normalizers; exported from both "open-model-selector" and "open-model-selector/utils".
• Venice supportsMultipleImages — added to TextCapabilities; extracted from model_spec.capabilities.
• Lint + format + pre-commit tooling — ESLint 9 (flat config, typescript-eslint + react-hooks + jsx-a11y), Prettier, Husky + lint-staged. npm run lint is a new CI gate.

Fixed

• OpenRouter cache pricing no longer silently dropped — normalizeTextModel now reads OpenRouter's input_cache_read and input_cache_write fields in addition to cache_input/cache_write.
• Capability fields reject non-boolean shapes — an API response like { supportsVision: { enabled: true } } now resolves to undefined instead of being cast to true.
• Sort button ARIA — aria-label describes the current sort state (not the next action); aria-pressed reflects whether "newest" is active.
• Pill contrast — capability pills (vision/reasoning/code/etc.) now meet WCAG AA in both light and dark mode.
• Dark-mode tooltip portal — .oms-hover-content gets explicit dark-mode overrides (background/border/shadow) in both media-query and class-based dark mode.
• Reduced-motion spinner — the loading spinner pulses instead of rotating when prefers-reduced-motion: reduce.

Changed

• BREAKING: TextModel.context_length is now number | undefined — previously the field defaulted to 0 when no context-length source resolved, which was indistinguishable from a model with genuinely zero context. Now undefined signals "unknown". Consumers doing if (model.context_length > 0) are unaffected; anything branching on === 0 will need to handle undefined.
• Icons in icons.tsx default to aria-hidden="true" (overridable via props).
• <ModelSelector> warns in dev mode when rendered with neither models nor baseUrl.
• now reference for deprecation filtering is captured once at mount (was refreshed on every popover open — caused memo cascades).
• handleModelSelect reads from a live ref so its identity is stable across favorite toggles. ModelItem's custom memo comparator works again.
• tsup no longer emits a no-op "use client" banner on the CJS build (ESM still gets it; esbuild places the CJS banner after the runtime preamble where it has no effect).
• CI runs npm run test:coverage — thresholds (70% statements/functions/lines, 65% branches) now actually gate PRs. Baseline: 95.79 / 90.36 / 96.09 / 98.3.
