Feature/global proxy (#596)
* refactor(proxy): simplify logging for better readability - Delete 17 verbose debug logs from handlers, streaming, and response_processor - Convert excessive INFO logs to DEBUG level for internal processing details - Add 2 critical INFO logs in forwarder.rs for failover scenarios: - Log when switching to next provider after failure - Log when all providers have been exhausted - Fix clippy uninlined_format_args warning This reduces log noise while maintaining visibility into key user-facing decisions. * fix: replace unsafe unwrap() calls with proper error handling - database/dao/mcp.rs: Use map_err for serde_json serialization - database/dao/providers.rs: Use map_err for settings_config and meta serialization - commands/misc.rs: Use expect() for compile-time regex pattern - services/prompt.rs: Use unwrap_or_default() for SystemTime - deeplink/provider.rs: Replace unwrap() with is_none_or pattern for Option checks Reduces potential panic points from 26 to 1 (static regex init, safe). * refactor(proxy): simplify verbose logging output - Remove response JSON full output logging in response_processor - Remove per-request INFO logs in provider_router (failover status, provider selection) - Change model mapping log from INFO to DEBUG - Change usage logging failure from INFO to WARN - Remove redundant debug logs for circuit breaker operations Reduces log noise significantly while preserving important warnings and errors. * feat(proxy): add structured log codes for i18n support Add error code system to proxy module logs for multi-language support: - CB-001~006: Circuit breaker state transitions and triggers - SRV-001~004: Proxy server lifecycle events - FWD-001~002: Request forwarding and failover - FO-001~005: Failover switch operations - USG-001~002: Usage logging errors Log format: [CODE] Chinese message Frontend/log tools can map codes to any language. New file: src/proxy/log_codes.rs - centralized code definitions * chore: bump version to 3.9.1 * style: format code with prettier and rustfmt * fix(ui): allow number inputs to be fully cleared before saving - Convert numeric state to string type for controlled inputs - Use isNaN() check instead of || fallback to allow 0 values - Apply fix to ProxyPanel, CircuitBreakerConfigPanel, AutoFailoverConfigPanel, and ModelTestConfigPanel * feat(pricing): support @ separator in model name matching - Refactor model name cleaning into chained method calls - Add @ to - replacement (e.g., gpt-5.2-codex@low → gpt-5.2-codex-low) - Add test case for @ separator matching * feat(proxy): add global proxy settings support Add ability to configure a global HTTP/HTTPS proxy for all outbound requests including provider API calls, speed tests, and stream checks. * fix(proxy): improve validation and error handling in proxy config panels - Add StopTimeout/StopFailed error types for proper stop() error reporting - Replace silent clamp with validation-and-block in config panels - Add listenAddress format validation in ProxyPanel - Use log_codes constants instead of hardcoded strings - Use once_cell::Lazy for regex precompilation * fix(proxy): harden error handling and input validation - Handle RwLock poisoning in settings.rs with unwrap_or_else - Add fallback for dirs::home_dir() in config modules - Normalize localhost to 127.0.0.1 in ProxyPanel - Format IPv6 addresses with brackets for valid URLs - Strict port validation with pure digit regex - Treat NaN as validation failure in config panels - Log warning on cost_multiplier parse failure - Align timeoutSeconds range to [0, 300] across all panels * feat(proxy): add local proxy auto-scan and fix hot-reload - Add scan_local_proxies command to detect common proxy ports - Fix SkillService not using updated proxy after hot-reload - Move global proxy settings to advanced tab - Add error handling for scan failures * fix(proxy): allow localhost input in proxy address field * fix(proxy): restore request timeout and fix proxy hot-reload issues - Add URL scheme validation in build_client (http/https/socks5/socks5h) - Restore per-request timeout for speedtest, stream_check, usage_script, forwarder - Fix set_global_proxy_url to validate before persisting to DB - Mask proxy credentials in all log outputs - Fix forwarder hot-reload by fetching client on each request * style: format code with prettier * fix(proxy): improve global proxy stability and error handling - Fix RwLock silent failures with explicit error propagation - Handle init() duplicate calls gracefully with warning log - Align fallback client config with build_client settings - Make scan_local_proxies async to avoid UI blocking - Add mixed mode support for Clash 7890 port (http+socks5) - Use multiple test targets for better proxy connectivity test - Clear invalid proxy config on init failure - Restore timeout constraints in usage_script - Fix mask_url output for URLs without port - Add structured error codes [GP-001 to GP-009] * feat(proxy): add username/password authentication support - Add separate username and password input fields - Implement password visibility toggle with eye icon - Add clear button to reset all proxy fields - Auto-extract auth info from saved URL and merge on save - Update i18n translations (zh/en/ja) * fix(proxy): fix double encoding issue in proxy auth and add debug logs - Remove encodeURIComponent in mergeAuth() since URL object's username/password setters already do percent-encoding automatically - Add GP-010 debug log for database read operations - Add GP-011 debug log to track incoming URL info (length, has_auth) - Fix username.trim() in fallback branch for consistent behavior
