#7 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 dependencies to their latest patch and minor releases and updates Cargo.lock.

Bumps serde, serde_json, thiserror, extism-pdk, and rstest in Cargo.toml and refreshes the lockfile. All upgrades stay within existing major version lines, so there are no code changes, behavior changes, or migration steps.
