Add missing options to ResumeSessionConfig for parity with create

[friggeri]

• Add model, systemMessage, availableTools, excludedTools, configDir,
  and infiniteSessions to resume session config in all SDKs
• Update client implementations to pass new options to server
• Add "Resume Options" documentation section
• Bump @github/copilot dependency to ^0.0.403

✅ Cross-SDK Consistency Review: PASSED

This PR demonstrates excellent cross-SDK consistency. All four SDK implementations (Node.js, Python, Go, and .NET) have been updated uniformly to add the same set of resume session options.

Verified Consistency

Added options to ResumeSessionConfig across all SDKs:

• ✅ model - Change model when resuming
• ✅ systemMessage - Override/extend system prompt
• ✅ availableTools - Restrict available tools
• ✅ excludedTools - Disable specific tools
• ✅ configDir - Override config directory
• ✅ infiniteSessions - Configure infinite session behavior

Implementation details:

• All four languages properly pass these new options to the session.resume RPC call
• Naming conventions are correctly applied:
  • Node.js/TypeScript: camelCase (e.g., systemMessage, configDir)
  • Python: snake_case (e.g., system_message, config_dir)
  • Go: PascalCase (e.g., SystemMessage, ConfigDir)
  • .NET: PascalCase (e.g., SystemMessage, ConfigDir)
• Documentation added with clear examples showing TypeScript usage

Additional Notes

The PR also bumps the @github/copilot dependency to ^0.0.403, which likely includes server-side support for these new resume options. This is the correct approach for ensuring feature parity between the SDKs and the underlying CLI.

No consistency issues found. 🎉

Pull request overview

This PR adds missing configuration options to ResumeSessionConfig across all SDKs (Node/TS, Python, Go, .NET) to achieve feature parity with CreateSessionConfig. The changes allow developers to modify session settings when resuming, such as changing the model, updating tool configurations, or adjusting system messages. The PR also bumps the @github/copilot dependency to version 0.0.403 and adds comprehensive documentation for the new resume options.

Changes:

• Added model, systemMessage, availableTools, excludedTools, configDir, and infiniteSessions options to ResumeSessionConfig in all SDKs
• Updated client implementations to pass new options to the server during session resume
• Added "Resume Options" documentation section with examples
• Bumped @github/copilot dependency from ^0.0.402 to ^0.0.403

✅ Cross-SDK Consistency Review

I've reviewed this PR for consistency across all four SDK implementations (Node.js/TypeScript, Python, Go, and .NET), and I'm pleased to report that this PR maintains excellent cross-language consistency.

Summary of Changes

This PR adds missing options to ResumeSessionConfig to achieve parity with CreateSessionConfig. The following new fields were added to all four SDKs:

Field	Purpose
model	Change the model when resuming a session
systemMessage	Override or extend the system prompt
availableTools	Restrict which tools are available (allowlist)
excludedTools	Disable specific tools (blocklist)
configDir	Override the default configuration directory
infiniteSessions	Configure infinite session behavior

✅ Consistency Verification

All four SDKs have been updated consistently:

• Node.js/TypeScript (nodejs/src/types.ts, nodejs/src/client.ts): ✅ All fields added
• Python (python/copilot/types.py, python/copilot/client.py): ✅ All fields added with proper snake_case naming
• Go (go/types.go, go/client.go): ✅ All fields added with proper PascalCase naming
• .NET (dotnet/src/Types.cs, dotnet/src/Client.cs): ✅ All fields added with proper PascalCase naming

🎯 API Naming Consistency

The implementations properly respect language conventions:

• TypeScript: model, systemMessage, availableTools, excludedTools, configDir, infiniteSessions (camelCase)
• Python: model, system_message, available_tools, excluded_tools, config_dir, infinite_sessions (snake_case)
• Go: Model, SystemMessage, AvailableTools, ExcludedTools, ConfigDir, InfiniteSessions (PascalCase for exported fields)
• .NET: Model, SystemMessage, AvailableTools, ExcludedTools, ConfigDir, InfiniteSessions (PascalCase properties)

📚 Documentation

The PR also includes comprehensive documentation in docs/guides/session-persistence.md with a table of all resume options and example usage, which benefits all SDK users.

🔍 Implementation Quality

All four implementations correctly:

1. Add the new fields to their ResumeSessionConfig types
2. Pass the fields to the JSON-RPC session.resume request with proper wire format conversion
3. Include appropriate comments/documentation
4. Maintain the same semantic behavior across languages

No cross-SDK consistency issues found. 🎉
