1. Add timeout to HAProxy response wait
- Use select() for non-blocking recv with 30s timeout
- Prevents indefinite blocking on slow/hung HAProxy
2. Log warnings for failed server clears
- haproxy_remove_domain now logs warnings instead of silent pass
- Helps debugging without breaking cleanup flow
3. Add HAPROXY_CONTAINER environment variable
- Container name now configurable (default: "haproxy")
- Used in reload_haproxy() and haproxy_check_config()
4. Add haproxy_add_servers() for bulk operations
- Add multiple servers in single call
- Accepts JSON array of server configs
- More efficient than multiple haproxy_add_server calls
5. Add wildcard domain support in haproxy_list_domains()
- New include_wildcards parameter (default: false)
- Shows .domain entries with (wildcard) label when enabled

1. Fix order: Save to disk FIRST, then update HAProxy
- Prevents inconsistency if HAProxy update succeeds but disk write fails
- Data is preserved correctly on restart
2. Add IPv6 support
- Use Python ipaddress module instead of regex
- Now accepts both IPv4 and IPv6 addresses
3. Extract atomic_write_file() helper
- Eliminates duplicated code in save_map_file, save_servers_config, haproxy_save_state
- Single source of truth for atomic file operations

Major improvements:
- Atomic file writes using temp file + rename pattern
- Structured logging with logging module (replaces print)
- StateField class for HAProxy state field indices
- Helper function get_backend_and_prefix() to reduce duplication
- Consistent exception chaining with 'from e'
- Proper fd/temp_path tracking to prevent resource leaks
- Added IOError handling in server management functions
Technical changes:
- save_map_file, save_servers_config, haproxy_save_state now use
atomic writes with tempfile.mkstemp() + os.rename()
- Standardized on 'set server state ready' (was 'enable server')
- All magic numbers for state parsing replaced with StateField class

Remove SSL/QUIC backend templates - all backends now use HTTP only
with SSL termination at HAProxy frontend. This improves performance
(~33% faster than HTTPS backends based on benchmarks).
Changes:
- server.py: Remove https_port parameter from all functions
- haproxy.cfg: Remove ssl/h3 server templates from pool backends
- CLAUDE.md: Update docs for HTTP-only backends and acme.sh

- Zero-reload domain management with map-based routing
- 100 pool backends with 10 server slots each
- Runtime API integration for dynamic configuration
- Auto-restore servers from persistent config on startup
- 17 MCP tools for domain/server management
