* refactor: remove the legacy agent-core v1 package
Delete packages/agent-core (v1 engine) and migrate node-sdk fully onto
agent-core-v2:
- node-sdk owns its public contract (error protocol, KimiConfig schema
and file IO, process-global logging facade, telemetry client
interface); event and interaction types re-export from
@moonshot-ai/protocol or agent-core-v2
- createKimiHarness is now the single harness factory, backed by the
v2 client; the v1 SDKRpcClient is deleted
- CLI and vscode run agent-core-v2 unconditionally;
KIMI_CODE_LEGACY_FLAG and useAgentCoreV1 are removed
- the wire.jsonl replay fold moves into agent-core-v2's replayBuilder
(foldWireRecords), and the v2 journal now persists tool-call display
so replay restores diff/todo displays
- TUI engineV2 branches collapse to the v2 path
* test(vscode): retry temp-dir teardown in replay-resume integration test
* feat(klient): contract-driven facade with http/ipc/memory transports
- add zod-validated contract sections (global/session/agent) under
src/contract and a facade exposing global.*, session(id).*, agent(id).*
- select transport once at creation via subpath entries
(@moonshot-ai/klient/http|ipc|memory); drop legacy channel/client/
httpChannel/wsChannel/wsKlient/proxy implementations
- absorb packages/server-e2e into packages/klient test/e2e suites
(dual-backend, legacy v1, v2 wire) and remove the server-e2e workspace
- expose model registry and catalog services on kap-server v2 RPC surface
* fix(klient): derive session status from agentActivityView
The engine retired its sessionActivity service in #1751 (session busy is
now derived from agent activity views), but the facade still called the
deleted wire channel and imported the deleted engine module, breaking
typecheck and every klient suite at import time.
- drop the sessionActivity contract/registry entries and mirror the
agentActivityView service instead (agent scope)
- compose session status() client-side from the pending interaction lists
and each agent's agentActivityView, keeping the retired service's
precedence and typing SessionStatus locally in the facade
- replace the deleted-channel call in the v2 smoke suite with a
sessionInteractionService probe
- fix the legacy image-file suite to wait with the harness's
waitForSessionBusy
