[BUG] Custom headers are not passed along by agentcore invoke in dev mode

[timle8n1]

Describe the bug
When running agentcore invoke with the --dev flag, headers are not passed along to the dev mode server. Is there a reason for this?

To Reproduce
Steps to reproduce the behavior:
Create an agent and try to load in a custom header

req_headers = getattr(context, 'request_headers', None) or {}
custom_value = req_headers.get("x-amzn-bedrock-agentcore-runtime-custom-value")

Start the agent in development mode

uv run agentcore dev

Invoke the agent in dev mode

uv run agentcore invoke --dev "Do something useful" --headers "value:awesome"

Expected behavior
custom_value should have the value awesome

Error Output
custom_value is empty
