Word Hunter: download ældre versioner

Imports German quest vocabulary from World of Warcraft together with its
encounter history, and suggests when a long-running word may be ready to
mark as known. Saved words can now be renamed without losing their learning
progress. Adds shuffled review sessions, masking of German separable verbs
on reverse cards, dyslexia-friendly reader fonts, bold and italic in the
book editor, and read-aloud that keeps the highlighted word on screen.
Starting up and saving are markedly faster on large libraries, and image
text recognition is no longer cut off while it is still running.

Contextual AI explanations for words and phrases: streamed answers from
OpenAI-compatible services, reasoning-effort levels, automatic explanations
for new words, optional visual context for scanned pages, a local cache, a
translator button, and configurable endpoint, model, and API key. Also
improves translation reliability and prevents duplicate durable saves from
blocking application shutdown.

Replaced background folder synchronization with explicit ZIP transfer
packages storing words and books as YAML records.
Added a 0-100% progress bar to desktop package export.
Fixed PC startup when the configured data folder is missing and sped up
shutdown.
Improved Android TTS, word sheet, PDF import, and startup, and added a
Chinese (Simplified) interface.

Made later vocabulary status decisions win reliably across devices.
Added a safe deterministic fallback for older vocabulary records.
Shortened Android startup and made library loading lighter.
Restricted Android cleartext traffic to the local Word Hunter backend.

Restored Reader keyboard focus after page changes.
Kept playback and repeated phrases anchored to the exact selected occurrence.
Deferred in-text review of newly learned words until the following day.
Kept scrolling Android word-card content below its fixed header.
Corrected Italian interface copy and built-in reader title headers.
