Summary

Adds support for the dotnet10 Lambda runtime, including local dev workflows.

Changes

• packages/sst/package.json: Updated aws-cdk-lib from 2.224.0 to 2.233.0 — the minimum version that includes CDKRuntime.DOTNET_10.
• packages/sst/src/constructs/Function.ts: Added dotnet10: CDKRuntime.DOTNET_10 to the supportedRuntimes map, making "dotnet10" a valid Runtime type.
• packages/sst/src/runtime/handlers/dotnet.ts: Added dotnet10 entries to both FRAMEWORK_MAP ("net10.0") and BOOTSTRAP_MAP ("dotnet10-bootstrap"), enabling local dev invocation via dotnet exec.
• packages/sst/support/dotnet10-bootstrap/: New bootstrap project targeting net10.0, with pre-built release/ binaries (built with dotnet 10 SDK).
• packages/sst/build.mjs: Added "dotnet10-bootstrap" to the list of support packages copied during build.

Usage

new Function(stack, "MyFunction", {
  runtime: "dotnet10",
  handler: "MyAssembly::MyNamespace.MyFunction::FunctionHandler",
});
