This commit introduces **support for source phase imports** within **Wrangler**, enabling developers to use the `import source` syntax for advanced module loading. It configures `esbuild` to recognize this syntax, ensuring that **WASM modules imported via `import source` are correctly processed**, copied to the output, and included in the worker bundle, even when `--no-bundle` is specified. This **new capability** also improves **Wrangler's worker format detection**, accurately identifying the 'modules' format when source phase imports are present. Overall, this **enhances Wrangler's bundling and deployment logic**, providing more robust handling for modern JavaScript module patterns.

This commit introduces a **robust build locking mechanism** within the **`worker-build` subsystem** to prevent concurrent build processes from corrupting shared output files. It implements a new `BuildLock` that directs all build output into a temporary staging directory (`build/.tmp/`) and uses an mtime-based heartbeat to coordinate and wait for other active builds. This **bug fix** addresses a critical concurrency issue by ensuring that `wrangler`'s worker builds are atomic. The change significantly enhances the **reliability and stability** of worker deployments by preventing build failures and inconsistent states when multiple commands trigger builds simultaneously.

This commit **introduces a comprehensive performance benchmarking suite** for the `workers-rs` project, establishing a **new capability** for continuous performance monitoring. It adds a dedicated `benchmark/` module containing Rust worker code (`benchmark/src/lib.rs`) for testing streaming and parallel sub-requests, along with Node.js scripts (`benchmark/run.js`, `benchmark/codspeed-convert.js`) to execute benchmarks against a worker server using Miniflare and convert results for CodSpeed. A new **GitHub Actions workflow** (`.github/workflows/codspeed.yml`) is also integrated to automate benchmark runs on push and pull requests, providing crucial insights into performance regressions and improvements for `workers-rs` applications. This suite allows developers to easily run and analyze performance metrics locally and within CI.

This commit performs a **dependency update** for the `wasm-bindgen` toolchain, upgrading it to version `0.2.113`.

This commit performs a **dependency update** for the **WebAssembly (Wasm) binding generation** toolchain, advancing `wasm-bindgen` and its related crates to version `0.2.112`. This **maintenance** task updates the `Cargo.toml` dependencies and the `wasm-bindgen` git submodule, ensuring the project utilizes the latest features and bug fixes from the `wasm-bindgen` ecosystem. Additionally, the `LATEST_WASM_BINDGEN_VERSION` constant in `worker-build/src/versions.rs` is updated to reflect this new baseline. This upgrade improves the overall stability and capabilities of **Rust-to-Wasm compilation and JavaScript interoperability**.

This commit delivers a **bug fix** and **refactoring** for the **`SecretStore`** module, resolving issues where `SecretStore::get()` could incorrectly return `None` or silently fail. It **removes an unnecessary `Fetcher` indirection** when constructing `SecretStore` from its JavaScript binding, ensuring the direct use of the binding's `.get()` method for proper method dispatch. Additionally, the commit **stops silently swallowing JavaScript errors** within `SecretStore::get()`, instead propagating them via `Result` to improve error visibility and reliability, aligning its behavior with the `Storage::get` pattern. This change significantly enhances the **runtime stability** and **predictability** of secret retrieval operations.

This commit primarily **updates the `wasm-bindgen` dependency** to version 0.2.110, alongside `web-sys` and the Rust toolchain, as a **maintenance** task. It also includes significant **refactoring** across various modules. Specifically, it standardizes string formatting for error messages and debug output in `test`, `worker-build`, and `worker-macros` components. Furthermore, it enhances the robustness of the **`worker` runtime** by updating `Closure` usage to unwind-safe variants like `Closure::wrap_assert_unwind_safe` in `Delay`, `DurableObject`, and `WebSocket` implementations.

This commit introduces **support for the `--panic-unwind` build option** for `worker-build`, enabling Rust panics within **Cloudflare Workers** to unwind rather than immediately aborting. This **new capability** involves updating the `worker-macros` and `worker` crates to wrap critical futures with `AssertUnwindSafe`, ensuring proper panic propagation and recovery in modules like `durable_object`, `event` handlers, and `wait_until` calls. The build process now conditionally inserts `criticalError` logic into the JavaScript shim, and comprehensive **testing infrastructure** has been added to validate unwind behavior. This significantly enhances the robustness and error handling capabilities of Rust-based Workers by allowing for more graceful panic recovery.

This commit **updates the Rust toolchain** configuration for the project, specifically upgrading the channel from version `1.83.0` to `1.87.0` within the `rust-toolchain.toml` file.
