fix: add missing __init__.py to Python template subpackages

[notgitika]

Description

Add empty init.py to model/ and mcp_client/ directories across all 6 Python framework templates, ensuring imports work correctly regardless of working directory or packaging method.

• Strands (model + mcp_client)
• LangChain/LangGraph (model + mcp_client)
• CrewAI (model only — no mcp_client dir)
• Google ADK (model + mcp_client)
• OpenAI Agents (model + mcp_client)
• AutoGen (model + mcp_client)

/strands review this PR and make sure that we are not missing anything. Don't make any changes. Look to see if we are missing these things anywhere else.

I think we are also missing __init__.py in one other subpackage. The src/assets/python/strands/capabilities/memory/ has no __init__.py. This directory contains session.py, and the strands main.py template imports it as:

from memory.session import get_memory_session_manager

PR Review: Missing __init__.py Files

I've completed a comprehensive review of this PR to identify any gaps in coverage.

✅ What This PR Successfully Addresses

The PR correctly adds __init__.py files to 11 directories across all 6 Python framework templates:

• AutoGen: model/ + mcp_client/
• CrewAI: model/ (no mcp_client directory)
• Google ADK: model/ + mcp_client/
• LangChain/LangGraph: model/ + mcp_client/
• OpenAI Agents: model/ + mcp_client/
• Strands: model/ + mcp_client/

❌ Critical Gap Found

Missing: src/assets/python/strands/capabilities/memory/__init__.py

Why This Matters

1. Template Rendering Logic: The BaseRenderer.ts (lines 55-59) copies the capabilities/memory/ directory to memory/ in the project root when hasMemory=true

2. Import Dependency: The strands/base/main.py (line 6) contains:

   from memory.session import get_memory_session_manager

3. Impact: Without __init__.py, the memory functionality will fail with ImportError for any Strands project that enables memory capabilities.

Evidence

• The snapshot test shows python/strands/capabilities/memory/session.py exists
• The snapshot test does NOT show python/strands/capabilities/memory/__init__.py
• Only Strands has this capabilities directory structure - other frameworks don't need it

Recommendation

Add an empty __init__.py file to src/assets/python/strands/capabilities/memory/ to complete this fix.

Additional Verification

I verified that:

• All other frameworks (AutoGen, CrewAI, Google ADK, LangChain/LangGraph, OpenAI Agents) are complete ✅
• No other Python directories in the templates need __init__.py files ✅
• This is the only missing file ✅

I think we are also missing __init__.py in one other subpackage. The src/assets/python/strands/capabilities/memory/ has no __init__.py. This directory contains session.py, and the strands main.py template imports it as:

Thanks for catching this @aidandaly24 I addressed this in the following commit.
