Bug Fixes:
- Wire up imageMethod speed setting in ImageCompressor (Fast/Average/Slow compression)
- Wire up createRpaAfter setting to automatically create RPA archives after compression
- Add validation to prevent compression when all media types are disabled
- Move progress polling to Dispatchers.IO to prevent UI freezing and ANRs
- Fix compression stats to track real totals and handle failures correctly
- Make file filtering case-insensitive for all extensions (.RPA, .RPYC, .RPY, etc.)

Technical Improvements:
- ImageCompressor now respects imageMethod setting for lossless compression effort
- CompressionManager tracks actual file counts (X/Y files) instead of misleading 100%
- Failed file compressions count original size (accurate reduction percentage)
- Empty folders/disabled types treated as graceful success instead of failure
- Progress updates show real progress with failed file counts
- File picker now accepts uppercase extensions from Windows distributions
- Python decompiler and RPA tool now case-insensitive for file extensions
- All I/O operations moved off main thread (countRpycFiles, file reads, etc.)

Version:
- Updated versionCode to 10
- Updated versionName to "1.7.1"

Implemented comprehensive APK compression feature that allows users to compress Ren'Py APKs with proper signing. Added keystore management system for importing, exporting, and managing signing keys, with options for random key generation and saved keystores. Introduced Settings activity for theme and configuration management. Enhanced file picker to support both directory and APK file selection for compression operations.

Added early validation to check for duplicate keystore names when creating a new key. Users now see an error immediately when clicking Continue instead of after the compression process completes.

Added ProGuard rules to protect critical components when minifyEnabled is true:
- Chaquopy Python bridge (reflection-based API)
- Enum valueOf() methods for settings serialization
- BouncyCastle crypto algorithms and providers
- APKSig library for APK signing
- FFmpeg-Kit native library bindings
- Data classes and ViewModels

Enables 41% APK size reduction (150MB -> 88MB) while maintaining full functionality.

Set minifyEnabled to true for release builds. Combined with ProGuard rules, this reduces APK size by 41% (150MB -> 88MB) while maintaining full functionality.

Added support for ARC-3.0 archive format (used by specific Ren'Py games) alongside standard RPA format. The .arc format uses the same internal structure as RPA-3.0 but with a different magic header.

Changes:
- Python: Added ARC-3.0 magic header recognition and parsing
- File picker: Accept both .rpa and .arc files when filtering archives
- UI: Display RPA icon for .arc files
- UI text kept as "RPA" only (no explicit .arc mentions)

Added ProGuard rules to preserve Sora Editor and TextMate language support classes, fixing syntax highlighting that was broken by minification. TextMate grammars are loaded dynamically using reflection and require these classes to remain unobfuscated.

Added optional "Try Harder Mode" for decompilation with user-facing controls:
- New dialog before decompilation with checkbox to enable aggressive mode
- Clear warning that it takes significantly longer
- Recommended for use only when default decompilation fails
- Python parameter passed through to unrpyc's try_harder option

This gives users fine-grained control for handling heavily obfuscated .rpyc files.

Implemented storage validation that checks archive size before extraction to prevent massive file expansions from filling up device storage.

Features:
- Calculate total extracted size from RPA index before extraction starts
- Check available device storage using StatFs
- Block extraction if insufficient storage (show required vs available)
- Warn if extraction >10GB or expansion ratio >20x (let user confirm)
- Normal extractions proceed immediately without dialogs

Python changes:
- Added get_total_size() method to RenPyArchive class
- Added get_extraction_info() wrapper function for Kotlin integration

Kotlin changes:
- Added validateAndExtract() to check storage before starting extraction
- Added getAvailableSpace() to query device storage
- Added formatSize() for human-readable size display
- Modified extraction flow to validate before proceeding

This prevents edge cases where archives expand massively (e.g., 1.5GB → 150GB) from crashing the app or filling device storage.

Made PendingIntent fully explicit by setting the component property directly. This prevents potential intent interception and satisfies GitHub security scanning.

Changes:
- Added explicit component to notification Intent
- Ensures only ProgressActivity can be launched from notification
- Maintains FLAG_IMMUTABLE for additional security

Resolves GitHub code scanning warnings at lines 171, 188, and 205.
