fix(proxy): log error when upstream TLS config creation fails
...
Previously the error was silently swallowed, causing the proxy to
fall back to default TLS settings (no custom CA, no mTLS, no SNI)
without any indication. Now the error is logged at ERROR level.

fix(proxy): prevent use-after-recycle in background cache refresh
...
Copy the request before spawning the background goroutine. The
fasthttp.RequestCtx is recycled after the handler returns, so passing
it to a goroutine causes data corruption under high concurrency.
The caller now AcquireRequest+CopyTo before go(), and the goroutine
releases it. backgroundRefresh no longer accepts ctx directly.

refactor(utils): add unified b2s/s2b conversion functions
...
Extract duplicate b2s/s2b functions from proxy/utils.go into
internal/utils/bytes.go. These are zero-allocation unsafe conversions
for byte slice <-> string conversion.
- Create utils.B2s() and utils.S2b() as unified implementations
- Update proxy/utils.go to call utils functions
- Add safety documentation about shared memory warning

feat(proxy): add configurable X-Forwarded-Host and X-Forwarded-Proto headers
...
Add `set_forwarded_host` and `set_forwarded_proto` options to control
whether the proxy automatically sets these headers. This fixes issues
with upstream servers that validate X-Forwarded-Host against known hosts.
Changes:
- Add SetForwardedHost/SetForwardedProto fields to ProxyHeaders struct
- Modify SetForwardedHeaders and WriteForwardedHeaders function signatures
- Update modifyRequestHeaders to read config and pass control parameters
- Update WebSocket call chain to support new config
- Add unit tests for new functionality
- Update default config generation (-g) to include new options
