v2.5.0

Added

• Top 100 User Words Frequency Engine (UserFrequencyDictionary): dynamic user lexicon tracking that learns your most-used words over time and prioritizes them in spellchecking, phonetic alignment, and candidate scoring.
• Context-Aware Russian Misrecognition Filtering: intelligent resolution for acoustic confusions (e.g. 'проявка' -> 'проверка' in testing/speech/sound contexts while preserving photography terminology).
• Strict Language Locking: automatic detection fallback that locks decoding to enabled languages when multilingual mode misdetects unselected languages.
• Audio Input Source Selector: microphone selection in Settings (System tab) and Menu Bar popover.

Changed

• Linguistic Sanitization: added automatic conversion of rogue Ukrainian glyphs and grammatical particles when transcribing in Russian mode.
• Microphone Buffer Drain: added hardware buffer flush delay before closing audio tap to capture ending syllables completely.
• Speech Boundary Padding: extended trailing audio padding from 150ms to 450ms in VAD conditioning to prevent cutting off trailing words and soft consonants.

Fixed

• Trailing Text Truncation: eliminated aggressive regex patterns and substring matching bugs in hallucination removal that previously deleted sentence endings.
• Waveform Width & Spring Physics: restored full 52-bar bouncy dynamics across the recording pill.
• Audio Hotkey Deadlock & Menu Bar Crashes: eliminated deadlock during rapid hotkey toggling and resolved MenuBarExtra presentation crashes.
