feat: add macOS local test support

[suxb201]

Summary

• Fix build.sh to use GO_LDFLAGS instead of LDFLAGS to avoid conflicts with Homebrew's environment variables
• Add test_local.sh for easy local testing on macOS/Linux with Homebrew Redis

Changes

1. build.sh: Changed LDFLAGS to GO_LDFLAGS to prevent conflicts when user's shell has LDFLAGS set by Homebrew packages (e.g., flex)

2. test_local.sh: New script for local testing

   • Automatically detects Redis version from PATH
   • Runs tests without modules flag (suitable for Homebrew/system Redis)
   • Supports passing additional arguments to pybbt

Usage

# Install Redis (macOS)
brew install redis

# Run all tests
./test_local.sh

# Run specific test file
./test_local.sh cases/rdb.py

# Run tests matching pattern
./test_local.sh -k "rdb"

Test Results (macOS with Redis 8.2.1)

All 6 tests passed locally:

• cases/aof.py ✓
• cases/auth_acl.py ✓
• cases/rdb.py ✓
• cases/scan.py ✓
• cases/sync.py ✓

Test plan

• Build succeeds on macOS with Homebrew environment
• All tests pass with Homebrew Redis 8.2.1
• Tests auto-detect Redis version

Accept a single pybbt target when args are provided

When arguments are passed, this branch still prepends cases, which gives pybbt two positional paths (cases and the user-supplied one). pybbt --help defines only one positional file_or_dir, so ./test_local.sh cases/rdb.py fails with unrecognized arguments instead of running that file as documented. This breaks the new “run specific test file” workflow whenever the user passes a positional target.
