Default streaming to false for compact MCP tool responses

[maatheusgois-dd]

Summary

• Default streaming to false on all build/test tools so MCP responses stay compact unless the caller opts in
• Centralize the streaming JSON Schema property in schema-constants.ts with an explicit default: false
• Add streaming to session defaults (bazel_ios_set_defaults), config profiles, and defaultStreaming file config
• Update streaming docs to reflect opt-in behavior

Scope

• MCP server/tools
• CLI commands or parsers
• Bazel build/test/discovery
• Simulator workflows
• Physical device workflows
• UI automation, screenshots, video, logs, or deep links
• LLDB debugging
• macOS, tvOS, watchOS, or visionOS workflows
• Swift Package Manager
• Daemon, session defaults, config, doctor, or setup
• Project scaffolding
• Docs, examples, or agent skills
• CI, release, packaging, or dependencies

Validation

• npm run lint
• npm run typecheck
• npm test
• npm run build
• npx vitest --run --coverage
• Manual MCP validation with Cursor or another MCP client
• Manual CLI validation with xcodebazelmcp ...
• Bazel workspace validation against a real Apple target
• Simulator validation
• Physical device validation

Compatibility

• Adds, removes, or renames MCP tools
• Changes CLI flags, command output, exit codes, or streaming behavior
• Changes config files, environment variables, defaults, or profiles
• Changes generated project scaffolding
• Changes package contents, dependencies, Node support, or release behavior
• Requires updates to docs, README, manifests, schemas, or skills
• No compatibility impact

Behavior change: Long-running tools no longer stream output by default. Agents or users that relied on implicit streaming must pass streaming: true or set it via bazel_ios_set_defaults.

Notes For Reviewers

• applyDefaults now always injects streaming: false when unset, so handlers see an explicit value
• Tool schema tests assert streaming.default === false for every tool that exposes the property
• npm test — 444 tests passed
