Chinesezjc 683c92cb2e fix(tools): correct Python SDK fidelity and language-dispatch contract
Address ds-review-bot v5/v6 review on the Python SDK renderer:
- resolveFlavor now takes a peekRuntime() reader: undefined (no runtime,
  the doc-catalog harvest) degrades to the TS flavor, but a mounted
  runtime whose language is absent from RUN_CODE_FLAVORS fails loud. This
  removes the try/catch that silently swallowed the invalid-language path
  and drops the /* v8 ignore */ that hid the flavor guard from coverage;
  wireSchemas validates the runtime before projecting schemas so the
  renderer-table rejection stays the canonical assembly error.
- py-types RESERVED drops the soft keywords match/case: they are legal as
  TypedDict fields and methods, so keeping them needlessly degraded
  common search/regex arg objects to dict[str, Any].
- py-types treats an object with omitted properties as {} like the unified
  validator and TS renderer do, so a closed empty object declares an empty
  TypedDict instead of a permissive dict[str, Any].
- README: symmetric jsonSchemaToPy->Any note; a stale zh SDK bullet and
  limitation corrected; link the service-wide-language limitation to its
  Agent Note.

core/ — product API spine

English | 中文

The session log, system-prompt assembly, tool registry, agent vocabulary, and concrete loop that form the harness's default control spine. These are product packages — the stable surface plugins and consumers build against.

Package Role ctx key
scope/ Scoped-context registration primitive (scope tags, scope-filtered dispatch) (library — no ctx key)
session/ Event-sourced session log + in-memory store ctx.sessions
system-prompt/ Prompt-section + tool-schema assembly registry ctx.systemPrompt
tools/ Scoped tool registry + pre-policy, guards, around-dispatch, post-policy, and final-result observation ctx.tools
agent/ Agent interface, live registry, process-local initiator scope, agent/* event vocabulary ctx.agents
agent-loop/ Concrete plugin implementing the public Agent contract and owning the loop driver ctx.agentLoop

scope/ is the one non-service package here: a dependency-free library (createScope/scopeOf/scopeTarget) the registries and the loop build per-agent scoping on — it sits below session/ and system-prompt/ in the module graph precisely so they can consume it without a cycle.

agent-loop is the one concrete implementation of the agent seam and lives here because it is the harness's default product loop. It runs each driver inside ctx.agents.withInitiator(). Extension plugins depend on agent, including when they need the initiating Agent, and never on agent-loop directly, so the loop stays swappable.

The default composition that wires this spine into a runnable agent lives in examples/agent-spine-demo: one bundle plugin that loads the control spine plus selected default capabilities (timer + llm + sessions + fallback session titles + system-prompt + tools + agents + invariants + the local skill family + tool-bash + workspace-context + agent-loop) and forwards agent-loop's agents list as its own config. It sits in examples/ — ready-to-run demo/reference bundles — not in core/: core/ ships the swappable spine pieces, while a demo bundle picks one concrete composition of them and adds a front door.
