⚡ Bolt: Pre-compile Regex in dictionary loops to eliminate allocations

[LeanBitLab]

💡 What: Extracted inline Regex("\\s+") instances within the dictionary processing loops of AppsBinaryDictionary and UserBinaryDictionary to pre-compiled SPACE_REGEX companion object properties.

🎯 Why: To eliminate unnecessary allocations and runtime Regex compilation overhead that previously occurred on every single word or app iteration during dictionary population.

📊 Expected Impact: Reduced garbage collection pressure and slightly faster dictionary loading in hot paths during typing or background updates.

🔬 Verification: Clean builds with ./gradlew :app:assembleStandardDebug and all unit tests passed with ./gradlew :app:testStandardDebugUnitTest. Verified zero regressions and no introduced em dashes.
