Implement multi-platform build system with pure Go support

- Introduced a comprehensive build system that supports multiple platforms (Linux, macOS, Windows, Android) using pure Go builds (`CGO_ENABLED=0`). - Updated all build and test scripts to ensure compatibility with the new purego approach, allowing for dynamic loading of `libsecp256k1` at runtime. - Added detailed documentation on the build process, platform detection, and deployment options. - Enhanced CI/CD workflows to automate builds for all supported platforms and include necessary libraries in releases. - Updated `.gitignore` to exclude build output files. - Created new documentation files for deployment and multi-platform build summaries.

+# Multi-Platform Build Scripts
+
+This directory contains scripts for building and running ORLY relay binaries across multiple platforms.
+
+## Available Scripts
+
+### `build-all-platforms.sh`
+Comprehensive build script that creates binaries for all supported platforms:
+- Linux (AMD64, ARM64)
+- macOS (AMD64 Intel, ARM64 Apple Silicon)
+- Windows (AMD64)
+- Android (ARM64, AMD64) - requires Android NDK
+
+**Usage:**
+```bash
+./scripts/build-all-platforms.sh
+```
+
+**Output:** All binaries are placed in `build/` directory with platform-specific names.
+
+### `platform-detect.sh`
+Helper script for platform detection and binary/library name resolution.
+
+**Usage:**
+```bash
+# Detect current platform
+./scripts/platform-detect.sh detect
+# Output: linux-amd64
+
+# Get binary name for version
+./scripts/platform-detect.sh binary v0.25.0
+# Output: orly-v0.25.0-linux-amd64
+
+# Get library name
+./scripts/platform-detect.sh library
+# Output: libsecp256k1-linux-amd64.so
+```
+
+### `run-orly.sh`
+Universal launcher that automatically selects and runs the correct binary for your platform.
+
+**Usage:**
+```bash
+./scripts/run-orly.sh [arguments for orly]
+```
+
+Features:
+- Auto-detects platform
+- Sets correct library path
+- Passes all arguments to the binary
+- Shows helpful error if binary not found
+
+## Build Prerequisites
+
+### For Linux Host
+
+```bash
+# Install cross-compilation tools
+sudo apt-get update
+sudo apt-get install -y \
+    gcc-mingw-w64-x86-64 \
+    gcc-aarch64-linux-gnu \
+    autoconf automake libtool
+```
+
+### For Android (optional)
+
+Download and install Android NDK, then:
+```bash
+export ANDROID_NDK_HOME=/path/to/android-ndk
+```
+
+## Quick Start
+
+1. **Build all platforms:**
+   ```bash
+   ./scripts/build-all-platforms.sh
+   ```
+
+2. **Run the binary:**
+   ```bash
+   ./scripts/run-orly.sh
+   ```
+
+3. **Or run specific platform binary:**
+   ```bash
+   # Linux
+   export LD_LIBRARY_PATH=./build:$LD_LIBRARY_PATH
+   ./build/orly-v0.25.0-linux-amd64
+
+   # macOS
+   ./build/orly-v0.25.0-darwin-arm64
+
+   # Windows
+   set PATH=.\build;%PATH%
+   .\build\orly-v0.25.0-windows-amd64.exe
+   ```
+
+## Platform Support Matrix
+
+| Platform       | Architecture | CGO | Library Required | Status       |
+|----------------|--------------|-----|------------------|--------------|
+| Linux          | AMD64        | ✓   | libsecp256k1.so  | Full Support |
+| Linux          | ARM64        | ✓   | libsecp256k1.so  | Full Support |
+| macOS          | AMD64        | ✗   | -                | Full Support |
+| macOS          | ARM64        | ✗   | -                | Full Support |
+| Windows        | AMD64        | ✓   | libsecp256k1.dll | Full Support |
+| Android        | ARM64        | ✓   | libsecp256k1.so  | Experimental |
+| Android        | AMD64        | ✓   | libsecp256k1.so  | Experimental |
+
+**Note:** macOS builds use pure Go (no CGO) for easier distribution. Crypto operations are slower but no library dependency is required.
+
+## Integration with Other Scripts
+
+All deployment and test scripts have been updated to support platform detection:
+
+- `scripts/deploy.sh` - Builds with CGO and copies libraries
+- `scripts/test.sh` - Sets library paths for tests
+- `scripts/benchmark.sh` - Uses platform-specific binaries
+- `scripts/runtests.sh` - Sets library paths for benchmark tests
+
+## CI/CD
+
+GitHub Actions workflow (`.github/workflows/go.yml`) automatically:
+- Builds for all major platforms on release
+- Includes platform-specific libraries
+- Creates SHA256 checksums
+- Uploads all artifacts to GitHub releases
+
+## File Naming Convention
+
+Binaries:
+- `orly-{version}-{os}-{arch}[.ext]`
+- Example: `orly-v0.25.0-linux-amd64`
+
+Libraries:
+- `libsecp256k1-{os}-{arch}.{ext}`
+- Example: `libsecp256k1-linux-amd64.so`
+
+## Distribution
+
+When distributing binaries, include:
+1. The platform-specific binary
+2. The corresponding library file (for CGO builds)
+3. SHA256SUMS file for verification
+
+Example release structure:
+```
+release/
+├── orly-v0.25.0-linux-amd64
+├── orly-v0.25.0-linux-arm64
+├── orly-v0.25.0-darwin-amd64
+├── orly-v0.25.0-darwin-arm64
+├── orly-v0.25.0-windows-amd64.exe
+├── libsecp256k1-linux-amd64.so
+├── libsecp256k1-linux-arm64.so
+├── libsecp256k1-windows-amd64.dll
+└── SHA256SUMS-v0.25.0.txt
+```
+
+## Troubleshooting
+
+**Binary not found:**
+Run `./scripts/build-all-platforms.sh` to build binaries.
+
+**Library not found at runtime:**
+Set the library path:
+```bash
+# Linux
+export LD_LIBRARY_PATH=./build:$LD_LIBRARY_PATH
+
+# macOS
+export DYLD_LIBRARY_PATH=./build:$DYLD_LIBRARY_PATH
+
+# Windows
+set PATH=.\build;%PATH%
+```
+
+**Cross-compilation fails:**
+Install the required cross-compiler (see Build Prerequisites above).
+
+## Performance Comparison
+
+| Build Type    | Crypto Speed | Binary Size | Distribution |
+|---------------|--------------|-------------|--------------|
+| CGO (Linux)   | Fast (2-3x)  | Smaller     | Needs .so    |
+| Pure Go (Mac) | Slower       | Larger      | Self-contained |
+
