#5 chore(deps): refresh compatible crate versions

Summary

Refresh compatible Rust dependencies: serde 1.0.229, serde_json 1.0.151, thiserror 2.0.20, regex 1.13.1, extism-pdk 1.4.1, rstest 0.26.1, plus a Cargo.lock update.

Why

Keep crawler/hoster plugins on current patch/minor crates without crossing crypto or Extism major lines.

Testing

• cargo test --lib (host target where .cargo/config.toml pins wasm32-wasip1)
• cargo clippy --lib --bins -- -D warnings

---

Summary by cubic

Refreshes compatible Rust crate versions in Cargo.toml and updates Cargo.lock to keep dependencies current without crossing major version lines. Updates serde, serde_json, thiserror, regex, extism-pdk, and rstest to their latest patch/minor releases. No breaking changes expected; the library tests and clippy checks pass.

Summary by CodeRabbit

• Chores
  • Updated several underlying dependencies to newer versions.
  • Retained the existing pinned version for the Extism runtime dependency.
