Fix major issues and implement improvements

FIXES: - Fixed --tiny --nvhevc to use MP4 container instead of WEBM - Added conflict detection for --x264 and --nvhevc flags - Fixed stats system to accumulate data properly (total_files, total_time, average_time) - Improved error handling for missing flag values IMPROVEMENTS: - Implemented actual progress tracking using FFmpeg stderr parsing - Added real-time progress bar with ETA calculation - Progress shows percentage complete and estimated time remaining - Stats now properly accumulate over time instead of overwriting TECHNICAL: - Added bufio import for progress parsing - Enhanced container compatibility logic - Better error messages for conflicting flags - Improved stats JSON structure with proper data types

 All notable changes to GWEncoder v3.0 will be documented in this file.

+## [3.1.0] - 2025-10-21
+
+### ✨ Added
+- Optional `--x264` codec flag to use H.264/x264 while preserving the existing AV1 presets structure
+  - Preset mappings: Fast, Web-optimized, Quick, Tiny
+  - Output filenames include `H264` identifier (e.g., `*-H264-*-GWELL.*`)
+  - Help text updated with usage and examples
+- Optional `--nvhevc` codec flag to use NVIDIA NVENC HEVC hardware encoding
+  - Preset mappings aligned to AV1 modes with CQ targets (Fast=26, Web=28, Quick=26, Tiny=30)
+  - Uses `hevc_nvenc`, `main10` profile, `rc-lookahead=32`, `spatial_aq=1`, `temporal_aq=1`, and `hvc1` tag
+  - Output filenames include `NVHEVC` identifier
+  - Help text updated with usage and examples
+
+### 🔧 Changed
+- Unified encoding path to support codec selection per mode without altering user workflows
+- Dynamic container/audio selection for codec compatibility:
+  - H.264 in Web mode switches container from WEBM → MKV automatically
+  - MP4 outputs prefer AAC audio; MKV/WEBM use Opus
+- Filenames and discovery exclude lists updated to avoid re-encoding generated outputs (`AV1-`, `H264-`, `NVHEVC-`)
+
+### 🐛 Fixed
+- Prevented invalid H.264-in-WebM outputs by automatically choosing MKV when `--x264` is used with `--web`
+
+### ⚠️ Notes
+- `--nvhevc` requires an NVIDIA GPU with NVENC support; functionality validated at argument/build level in this environment but not runtime-encoded due to lack of NVIDIA hardware.

+Looking at your gwencoder code, I can see a few areas that could use some attention, dude.
+Issues I spotted:
+
+The progress tracking claims exist but aren't actually implemented - You get the total duration but never use it to show actual progress during encoding. The encoding just runs silently until completion.
+Error handling for the --abr flag could leave audioBitrate empty - If someone passes --abr as the last argument without a value, you'll skip it but won't handle the missing value gracefully.
+The stats system is pretty basic - It just overwrites the stats file each time instead of actually tracking cumulative data. Your "total_files" is always "1" (as a string, not even an int).
+Conflicting codec flags aren't handled - If someone passes both --x264 and --nvhevc, the last one wins silently. Should probably error out or at least warn.
+The FFmpeg stderr capture for progress is collected but not processed - You're capturing stderr into a buffer but only dumping it on errors. FFmpeg outputs progress info to stderr that you could parse.
+Container compatibility logic is scattered - The rules about which codecs work with which containers are spread throughout the code and could be centralized.
+
+implement actual progress tracking using FFmpeg's stderr output parse the time codes and show a nice progress bar with ETA
+
+that stats system could actually accumulate data properly to be useful to see your total encoding time over weeks/months.
