feat: add CI workflow, trust badges, and fix Bedrock extended thinking

- Add GitHub Actions CI workflow with cross-platform testing, clippy,
  format checks, and security audit
- Add trust badges to README: CI status, docs.rs, GitHub stars,
  last commit, MSRV (Rust 1.85+), platform support
- Fix extended thinking + tool use error for Bedrock by ensuring
  Reasoning blocks are sorted first in assistant messages (satisfies
  AWS API requirement that thinking blocks precede tool_use blocks)
