nullkey 567d7ac74e feat(cli): --format / NDJSON / chat & agent invoke / MCP / SetAgentHelp / signal-aware ctx / kb create --storage-provider
Adds the structured-output and agent-help surface plus root-level signal
handling so AI agents (and humans working through pipes) get a stable
wire contract.

* --format text|json|ndjson flag, registered per-command on outputs that
  need it; default text on TTY, json on pipe. --jq <expr> pairs with json
  / ndjson to filter or project. FormatOptions absorbs JQ; WantsJSON()
  helper for the JSON dispatch.
* WriteNDJSON helper in internal/format/ (per ndjson.org: one JSON value
  per line, arrays split element-per-line, empty slice → zero bytes).
* chat / agent invoke wire --format ndjson via SDK StreamResponse /
  AgentStreamResponse 1:1 passthrough. Both commands detect ctx.Cancelled
  in every stream + session-create path and emit a stable
  "operation.cancelled" code on Ctrl-C / SIGTERM.
* main.go wires signal.NotifyContext(SIGINT, SIGTERM) into the root
  context so long-running commands run their cancellation cleanup
  (re-emit auto-created session id, etc); the process exits 130 when
  the context was signal-cancelled, matching Unix convention.
* MCP chat / agent_invoke output schemas extended with thinking /
  tool_calls / assistant_message_id (server-side accumulated; MCP
  tools/call has no standard partial-response). doc_view and doc_download
  now use doc_id (not knowledge_id) so agents see a single id naming
  convention across all tools — matches the chunk_list / search_chunks
  schemas and the CLI's <doc-id> positional.
* SetAgentHelp(cmd, AgentHelp{...}) — opt-in machine-friendly --help
  payload activated by WEKNORA_AGENT_HELP=1. Applied to chat / kb list.
* kb create --storage-provider <local|minio|cos|tos|s3|oss|ks3> — sets
  the new KB's storage_provider_config.provider at creation time (server
  does not expose it on update). Required on self-hosted deployments
  where the server-side default doesn't pre-populate a provider —
  without it, subsequent doc upload returns a misleading "kb not found".

// Package-level note:
//
// SetAgentHelp wires structured agent-targeted help onto a cobra command.
// Current coverage: chat, kb list. Adding it to another command requires
// touching only that command's NewCmd (a 5-line copy of the existing call
// sites).
