fix: remove hardcoded branch names from push/pull operations

- Remove hardcoded "main" branch from git push and pull commands
- Let Git automatically detect and use current branch
- Add comprehensive tests for different branch names (main, master, develop)
- Fixes GitHub issue #14 where operations failed on repos using "master"

-# Release Process
-
-This document describes how to create releases for the lnk project using GoReleaser.
-
-## Prerequisites
-
-- Push access to the main repository
-- Git tags pushed to GitHub trigger releases automatically
-- GoReleaser is configured in `.goreleaser.yml`
-- GitHub Actions will handle the release process
-- Access to the [homebrew-lnk](https://github.com/yarlson/homebrew-lnk) tap repository
-- **Personal Access Token** set up as `HOMEBREW_TAP_TOKEN` secret (see Setup section)
-
-## Setup (One-time)
-
-### GitHub Personal Access Token
-
-For GoReleaser to update the Homebrew formula, you need a Personal Access Token:
-
-1. Go to GitHub Settings → Developer settings → Personal access tokens → Tokens (classic)
-2. Click "Generate new token" → "Generate new token (classic)"
-3. Name: "GoReleaser Homebrew Access"
-4. Scopes: Select `repo` (Full control of private repositories)
-5. Generate and copy the token
-6. In your `yarlson/lnk` repository:
-   - Go to Settings → Secrets and variables → Actions
-   - Add new repository secret: `HOMEBREW_TAP_TOKEN`
-   - Paste the token as the value
-
-This allows GoReleaser to automatically update the Homebrew formula in [homebrew-lnk](https://github.com/yarlson/homebrew-lnk).
-
-## Creating a Release
-
-### 1. Ensure everything is ready
-
-```bash
-# Run all quality checks
-make check
-
-# Test GoReleaser configuration
-make goreleaser-check
-
-# Test build process
-make goreleaser-snapshot
-```
-
-### 2. Create and push a version tag
-
-```bash
-# Create a new tag (replace x.y.z with actual version)
-git tag -a v1.0.0 -m "Release v1.0.0"
-
-# Push the tag to trigger the release
-git push origin v1.0.0
-```
-
-### 3. Monitor the release
-
-- GitHub Actions will automatically build and release when the tag is pushed
-- Check the [Actions tab](https://github.com/yarlson/lnk/actions) for build status
-- The release will appear in [GitHub Releases](https://github.com/yarlson/lnk/releases)
-- The Homebrew formula will be automatically updated in [homebrew-lnk](https://github.com/yarlson/homebrew-lnk)
-
-## What GoReleaser Does
-
-1. **Builds binaries** for multiple platforms:
-
-   - Linux (amd64, arm64)
-   - macOS (amd64, arm64)
-   - Windows (amd64)
-
-2. **Creates archives** with consistent naming:
-
-   - `lnk_Linux_x86_64.tar.gz`
-   - `lnk_Darwin_arm64.tar.gz`
-   - etc.
-
-3. **Generates checksums** for verification
-
-4. **Creates GitHub release** with:
-
-   - Automatic changelog from conventional commits
-   - Installation instructions
-   - Download links for all platforms
-
-5. **Updates Homebrew formula** automatically in the [homebrew-lnk](https://github.com/yarlson/homebrew-lnk) tap
-
-## Manual Release (if needed)
-
-If you need to create a release manually:
-
-```bash
-# Export GitHub token
-export GITHUB_TOKEN="your_token_here"
-
-# Create release (requires a git tag)
-goreleaser release --clean
-```
-
-## Testing Releases Locally
-
-```bash
-# Test the build process without releasing
-make goreleaser-snapshot
-
-# Built artifacts will be in dist/
-ls -la dist/
-
-# Test a binary
-./dist/lnk_<platform>/lnk --version
-```
-
-## Installation Methods
-
-After a release is published, users can install lnk using multiple methods:
-
-### 1. Shell Script (Recommended)
-
-```bash
-curl -sSL https://raw.githubusercontent.com/yarlson/lnk/main/install.sh | bash
-```
-
-### 2. Homebrew (macOS/Linux)
-
-```bash
-brew tap yarlson/lnk
-brew install lnk
-```
-
-### 3. Manual Download
-
-```bash
-# Download from GitHub releases
-wget https://github.com/yarlson/lnk/releases/latest/download/lnk_Linux_x86_64.tar.gz
-tar -xzf lnk_Linux_x86_64.tar.gz
-sudo mv lnk /usr/local/bin/
-```
-
-## Version Numbering
-
-We use [Semantic Versioning](https://semver.org/):
-
-- `v1.0.0` - Major release (breaking changes)
-- `v1.1.0` - Minor release (new features, backward compatible)
-- `v1.1.1` - Patch release (bug fixes)
-
-## Changelog
-
-GoReleaser automatically generates changelogs from git commits using conventional commit format:
-
-- `feat:` - New features
-- `fix:` - Bug fixes
-- `docs:` - Documentation changes (excluded from changelog)
-- `test:` - Test changes (excluded from changelog)
-- `ci:` - CI changes (excluded from changelog)
-
-## Homebrew Tap
-
-The Homebrew formula is automatically maintained in the [homebrew-lnk](https://github.com/yarlson/homebrew-lnk) repository. When a new release is created:
-
-1. GoReleaser automatically creates/updates the formula
-2. The formula is committed to the tap repository
-3. Users can immediately install the new version via `brew install yarlson/lnk/lnk`
-
-## Troubleshooting
-
-### Release failed to create
-
-1. Check that the tag follows the format `vX.Y.Z`
-2. Ensure GitHub Actions has proper permissions
-3. Check the Actions log for detailed error messages
-
-### Missing binaries in release
-
-1. Verify GoReleaser configuration: `make goreleaser-check`
-2. Test build locally: `make goreleaser-snapshot`
-3. Check the build matrix in `.goreleaser.yml`
-
-### Changelog is empty
-
-1. Ensure commits follow conventional commit format
-2. Check that there are commits since the last tag
-3. Verify changelog configuration in `.goreleaser.yml`
-
-### Homebrew formula not updated
-
-1. Check that the GITHUB_TOKEN has access to the homebrew-lnk repository
-2. Verify the repository name and owner in `.goreleaser.yml`
-3. Check the release workflow logs for Homebrew-related errors
-4. Ensure the homebrew-lnk repository exists and is accessible
