chore(release): v0.1.0 - Dart 3.13 modernization, primary constructors, and response mixins

[3d24rd0]

Description

This PR prepares the v0.1.0 release for dart_valkey, modernizing the entire codebase with modern Dart 3.13 features, cleaner architecture, enhanced error reporting, and complete documentation.

Summary of Changes

• Dart 3.13 & Dependency Upgrades:
  • Upgraded Dart SDK constraint to >=3.13.0 <4.0.0.
  • Updated dev dependencies (coolint: ^3.0.0, meta: ^1.19.0, mockito: ^5.8.1, test: ^1.32.0, coverage: ^1.15.1).
  • Resolved 100+ linter warnings and enforced strict typing rules.
• Primary Constructors (Dart 3.13):
  • Migrated 70+ command classes and models (PubSubMessage) to Primary Constructors (final class GetCommand(final String key) ...), removing nearly 1,000 lines of boilerplate.
• Response Parsing Mixins:
  • Refactored command responses to use reusable base mixins (OkStringResponse, OkBoolResponse, ExpectOkBoolResponse, PongBoolResponse, ResetStringResponse).
  • Replaced minified runtimeType in error messages with human-readable commandName extracted from commandParts.
• Documentation & Publishing:
  • Updated README.md with TLS configuration, self-signed certificate handling (onBadCertificate), client options, and custom commands.
  • Added .pubignore to exclude benchmark/ and coverage/ from published packages on pub.dev.
  • Updated CHANGELOG.md with 0.1.0 release notes.

Verification

• dart format . applied.
