Extends the dictionary system beyond StarDict/MDict with two more open
formats and a pluggable Web Search tier so users can fall back to online
sources when their offline bundles miss a word.
Formats:
- DICT (dictd, RFC 2229): .index + .dict.dz bundles. Shared DictZip
parsing with StarDict via new dictZip.ts helper.
- Slob (Aard 2): self-contained .slob containers, zlib-compressed
utf-8 entries; non-zlib/non-utf-8 bundles flagged unsupported at
import.
Web Search:
- Built-in templates for Google, Urban Dictionary, Merriam-Webster
(seeded into providerOrder, disabled by default).
- Custom URL templates via %WORD% placeholder, URL-encoded at
substitution; entries persist in settings.webSearches.
- V1 renders an "Open in {{name}}" external link (iframe embedding is
blocked by every major target site's X-Frame-Options).
UI:
- CustomDictionaries panel: flat outline-primary buttons for Import /
Add Web Search, end-aligned type badges for a uniform column,
hover states, compact tips block.
- Dictionary popup: bottom-right Manage icon (tooltip-only) deep-links
into Settings → Language → Dictionaries; rounded-corner clipping fix
on the tab strip.
File picker accepts .index and .slob; importer recognizes DICT and
Slob bundles and reads bundle metadata for friendly names.
Tests cover DICT/Slob readers and providers with real freedict-eng-nld
fixtures, web search substitution + provider rendering, and the new
store CRUD for web searches.
