Re-wrap bare IPv6 hosts after stripping ports so HTTPS redirect URLs stay valid. Add a regression test covering bracketed IPv6 hosts in redirect responses.
Make the non-graceful HTTPS redirect path shut down all sibling servers after any server returns, so cleanup stays consistent with the graceful path and partial shutdowns do not leave the redirect listener running.
Support explicit redirect host source selection for HTTP-to-HTTPS redirects with ordered header lookup, fixed host mode, and strict validation. Document the new redirect option relationships and add focused tests for 426 fallback, conflict checks, and non-graceful startup errors.
Replace the old RunShutdown and RunTLS style entry points with a single Run(opts...) API for v1. Add focused startup semantics tests, keep TLS and graceful shutdown independent, ensure sibling servers are cleaned up on startup failure, and update docs to match the new option-based startup model.
- Implemented \`applyDefaultServerConfig\` in \`Engine\` to apply \`serverProtocols\` to \`http.Server\`.
- Uncommented all calls to \`applyDefaultServerConfig\` in \`serve.go\`.
- Refactored \`SetProtocols\` and added internal \`setProtocols\` to ensure user-defined protocols are not overwritten by framework defaults in \`RunTLS\`.
- Added exhaustive tests in \`protocols_test.go\` to verify protocol inheritance and persistence.
- Created a detailed \`docs\` directory with Chinese documentation for all major features.
- Implemented \`BaseContext\` propagation in \`Engine\` to allow long-lived connections (like SSE) to receive shutdown signals.
- Added \`Engine.Context()\` to provide access to the shutdown context.
- Updated \`docs/sse.md\` with a guide on handling graceful shutdowns.
- Cleaned up temporary build/update scripts.
