v0.4.0

Highlights

• Expanded book support with charts, new releases, Top 250, ratings, comments, reviews, notes, public collections, and Markdown/CSV/JSON exports.
• Improved personal movie data workflows with safer collection parsing, statistics, paced exports, partial-result warnings, and structured JSON output for analysis.
• Hardened authentication and account mutations: explicit browser/profile selection, platform-standard storage, account verification, safer CSRF handling, and secure manual import from stdin or Netscape cookies.txt.
• Refactored public, authenticated-read, and mutation API boundaries; added response validation, retry/backoff behavior, more reliable pagination, clearer help, and stable structured errors.
• Updated the runtime and tooling stack, strengthened CI/release checks, and expanded automated coverage.
