调研方向

从 src/cli/primitives/AgentPrimitive.tsx 中的 handleByoPath 开始，将其 runtime 和 entrypoint 处理与 src/cli/operations/agent/generate/schema-mapper.ts 中的 DEFAULT_RUNTIME_BY_LANGUAGE 和 DEFAULT_ENTRYPOINT_BY_LANGUAGE 进行比较。验证 BYO TypeScript agent 是否记录 NODE_22 和 main.js，同时保留现有的 Other 行为，然后确认 packaging 不再选择 Python CodeZip 路径。

描述

bug
Description

agentcore add agent --type byo --language TypeScript registers the agent with "runtimeVersion": "PYTHON_3_14" in agentcore.json, ignoring --language. Packaging then selects the Python CodeZip packager and fails looking for pyproject.toml, so the BYO + TypeScript combination advertised by the --language help text (Python (create), or Python/TypeScript/Other (BYO)) cannot succeed with CLI flags alone.

Steps to Reproduce
  1. Create a project and add a BYO TypeScript agent: 
    agentcore create --name ByoRepro --no-agent
cd ByoRepro
agentcore add agent --name ByoRepro --type byo --code-location app/ByoRepro --entrypoint main.ts --language TypeScript --build CodeZip --framework Strands --model-provider Bedrock --memory none
  2. Put a TypeScript agent in app/ByoRepro/ (main.ts + package.json, npm install run).
  3. Run agentcore package (or agentcore deploy) and observe the Python packager error. Inspect agentcore/agentcore.json to see the registered runtimeVersion.
Expected Behavior

With --language TypeScript, the BYO path writes "runtimeVersion": "NODE_22" and defaults the entrypoint to main.js, the way the create path does via DEFAULT_RUNTIME_BY_LANGUAGE / DEFAULT_ENTRYPOINT_BY_LANGUAGE. (main.js because the Node CodeZip packager bundles the main.ts source into main.js, and the service rejects a .ts entrypoint for Node runtimes: Entrypoint file type does not match your selected runtime. For NODE_22 runtime, your file should end with .js extension.)

Actual Behavior
  1. agentcore/agentcore.json gets a Python runtime despite --language TypeScript: 
    {
  "name": "ByoRepro",
  "build": "CodeZip",
  "entrypoint": "main.ts",
  "codeLocation": "app/ByoRepro/",
  "runtimeVersion": "PYTHON_3_14",
  "networkMode": "PUBLIC",
  "protocol": "HTTP"
}
  2. Packaging fails: Required project file not found: .../app/ByoRepro/pyproject.toml.

Additional Context

Root cause: handleByoPath in src/cli/primitives/AgentPrimitive.tsx hardcodes runtimeVersion: DEFAULT_PYTHON_VERSION and never consults options.language, while the create path maps language through DEFAULT_RUNTIME_BY_LANGUAGE / DEFAULT_ENTRYPOINT_BY_LANGUAGE (src/cli/operations/agent/generate/schema-mapper.ts).

Verified workaround: hand-editing agentcore.json after add agent ("runtimeVersion": "NODE_22", "entrypoint": "main.js") makes the same project deploy and invoke successfully, so the defect is confined to what the BYO path writes.

--language Other is BYO-only and has no entry in DEFAULT_RUNTIME_BY_LANGUAGE; this report is only about TypeScript silently mapping to Python.

I'm happy to send a PR applying the two language maps in handleByoPath (Python/TypeScript only, current behavior preserved for Other).
