docs: streamline README — simplify structure, direct users to official website (#497) * feat(Security): add Basic auth, AuthScheme enum, and refine auth provider system > > - Add BasicAuthProvider with EncodeCredential helper (RFC 7617) > - Add AuthScheme enum (Hmac/Bearer/ApiKey/Basic) for explicit auth selection > - Add BasicUsername/BasicPassword fields through full config pipeline > - Rename UpdateAuth() to HttpAuth() for naming consistency > - Fix factory priority: explicit scheme now takes precedence over HMAC default > - Flows through: UpdateConfiguration → UpdateRequestBuilder → ProcessContract > → ConfigurationMapper → GeneralUpdateBootstrap → ClientStrategy > → HttpDownloadSource → VersionService → HttpAuthProviderFactory > > Breaking: UpdateAuth() renamed to HttpAuth() > > Co-Authored-By: Claude Opus 4.8 * fix: restore test compilation and address Copilot review feedback > > - Fix test compilation: add authScheme/BasicUsername/BasicPassword to > HttpDownloadSourceTests, ProcessContractTests, IpcEncryptionTests, > ProcessContractProviderTests > - Fix BootstrapFullParameterMatrixTests: UpdateAuth -> HttpAuth > - Fix duplicate

tag in AbstractBootstrap.cs > - Add [Obsolete] UpdateAuth() shim for backward compatibility > - Fix EncodeCredential exception doc (throws ArgumentException, not ArgumentNullException) > - Add missing doc for authScheme in factory Create method > - Rename SetAuthScheme parameter from 'scheme' to 'authScheme' > - Update BasicUsername/BasicPassword docs to reference AuthScheme.Basic enum > - Fix basicPassword param doc in VersionService.Validate > > Co-Authored-By: Claude Opus 4.8 * docs: streamline README — remove redundant sections, replace GeneralSpacestation with Official Website link Removed sections: Supported Features, Infrastructure, Quick Start, Supported Frameworks, Operating Systems, AI Wiki, Contact us. Replaced GeneralSpacestation Product Introduction with 🚀 Official Website link pointing to justerzhu.cn. Updated banner text to reference the official website instead of the removed bottom contact section. Applied to both EN and ZH-CN versions. Co-Authored-By: Claude Opus 4.8 * fix: resolve IPC file-locking race causing flaky test failures in CI Three related fixes: 1. IpcEncryption.DecryptFromFile: replace File.ReadAllBytes with FileStream using FileShare.ReadWrite|FileShare.Delete, and catch IOException gracefully so concurrent access (common in parallel test runs) returns null instead of crashing. 2. GeneralUpdateBootstrap.InitializeFromEnvironment: wrap IPC receive in try-catch, handle null/missing encoding gracefully, and treat any corrupted IPC data as 'no IPC data available' instead of letting exceptions propagate. 3. IPC test classes: add [Collection("IpcTests")] to serialize tests that share the deterministic file path, plus constructor-level file cleanup to prevent stale data from parallel test runs leaking between test classes. Root cause: every new GeneralUpdateBootstrap() reads the deterministic IPC file at %TEMP%/GeneralUpdate/ipc/process_info.enc. With xUnit running tests in parallel, multiple instances raced to read+delete the same file, causing IOException on Windows CI.
