Consolidate Go initialism casing

[qmuntal]

Summary

Consolidates Go identifier initialism casing across the Go code generator, generated RPC/session types, public Go SDK APIs, docs, and tests so the SDK uses one idiomatic naming path. The generator now routes Go identifier words through a shared helper, adds plural casing overrides, and aligns hand-written connection APIs with the same casing.

Initialism changes

• Api -> API for generated API wrapper types, fields, and registration helpers.
• Rpc -> RPC for generated RPC wrapper types, constructors, and session fields.
• Mcp -> MCP for MCP-related generated types, events, hooks, config fields, permissions, and tool helpers.
• Sse -> SSE for SSE transport enum names.
• Ado -> ADO for ADO working-directory host type enum names.
• Sdk -> SDK for SDK protocol version and extension SDK path symbols.
• Fs -> FS for session filesystem provider/config/adapter/error/RPC types.
• Url/Urls -> URL/URLs for URL-bearing generated identifiers.
• Uri/Uris -> URI/URIs, including UriConnection -> URIConnection.
• Id/Ids -> ID/IDs through the shared helper and plural override.
• Tcp -> TCP, including TcpConnection -> TCPConnection.
• Adds consolidated recognition for CLI, HMAC, and UTC so future generated names use idiomatic Go casing.

Validation

Ran npm run generate:go and git diff --check. Tests not run, per request.

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

This PR standardizes Go identifier casing to follow Go initialism conventions (e.g., MCP, RPC, SDK, GitHub, URL, FS) across the code generator, generated RPC bindings, SDK types, and tests.

Changes:

• Updated Go codegen casing rules (initialisms + explicit overrides like GitHub) and regenerated code accordingly.
• Renamed many exported Go SDK/RPC symbols to initialism-correct forms (e.g., SessionFS, ServerRPC, UIInputOptions, SDKProtocolVersion).
• Updated unit and E2E tests plus documentation to match the new exported names.

go/types.go:1

• Renaming exported fields/types (e.g., ClientOptions.SessionFs→SessionFS) is a breaking change for SDK consumers. If backward compatibility is required, consider providing a compatibility shim (mandatory if the Go SDK API is expected to be stable): keep the old SessionFs field as deprecated and map it internally to SessionFS, and add type aliases for renamed exported types where possible (e.g., type SessionFsConfig = SessionFSConfig).

  go/sdk_protocol_version.go:1
• Renaming exported symbols SdkProtocolVersion/GetSdkProtocolVersion to SDKProtocolVersion/GetSDKProtocolVersion is a breaking API change. To preserve source compatibility, consider adding deprecated wrappers/aliases (e.g., an exported const SdkProtocolVersion = SDKProtocolVersion and func GetSdkProtocolVersion() int { return GetSDKProtocolVersion() }) while keeping the new names as the preferred API.
