PR title

Add ServerRuntimeConfig + runtime headers, expose transport in /info, require runtime_config in create_server

PR description (short)

• Introduce ServerRuntimeConfig with transport and version metadata; pass it through ServerState.
• Add request headers to all Keboola API calls via SessionStateMiddleware:

User-Agent: Keboola MCP Server/{version} app_env={env}
MCP-Server-Transport: {stdio|sse|streamable-http|http-compat}
MCP-Server-Versions: keboola-mcp-server/{x} mcp/{y} fastmcp/{z}

• /info now returns serverTransport and library versions.
• CLI constructs and passes runtime_config based on --transport.
• BREAKING (library API): create_server(config, *, runtime_config, ...) now requires runtime_config.
• Bump version to 1.20.4; tests updated.
• Visibility: internal (not user-facing UI behavior).

release notes

• Update README.md to cover branch support and transport instruction. Refactored into two section - Remote and Local Setup.
• Introduced ServerRuntimeConfig and propagated runtime metadata (transport and versions).
• All outgoing Keboola API calls include MCP-Server-Transport and MCP-Server-Versions headers; User-Agent retained.
• /info endpoint includes serverTransport and library versions.
• BREAKING for library consumers: create_server requires runtime_config.
• Version bumped to 1.20.4.
• Visibility: internal; end users won’t notice changes.

plans for customer communication

• No end-user communication needed.
• Notify integrators/library consumers about the create_server signature change and new headers; update README/examples.

impact analysis

• Worst case(local code): third-party code calling create_server(config) without runtime_config fails to start.
• Potential issue: environment without package metadata could affect version resolution; headers fall back to UA default but should be validated in target environment.

change type

Feature (with a breaking change for the local create_server).

justification

• Standardizes runtime metadata, improves observability/diagnostics across transports, and enables consistent client identification.

deployment plan

• Merge PR; tag main as v1.20.4.

rollback plan

• Revert PR; retag previous release. v1.20.3

post release support plan

• Verify mcp.keboola.com/ returns expected serverTransport and versions.
• Smoke test stdio, SSE, and streamable-http transports.
• Confirm presence of new headers in outgoing requests in logs/mock tests.
• Update docs/snippets for create_server usage.
• Check also events whether include serverTransport info.
