feat(agent): MCP-correct chat agent shim on top of LiteLLM

New package @mcpctl/agent that replaces LiteLLM's broken MCP
integration (dropped Mcp-Session-Id, ignored tools/list_changed) with
a thin ~200 LOC loop built on @modelcontextprotocol/sdk +
openai SDK. LiteLLM stays in its actual lane — OpenAI-compatible model
routing — and this agent handles MCP correctly.

Core (src/agent.ts):
  - StreamableHTTPClientTransport for MCP (auto-preserves Mcp-Session-Id).
  - Re-fetches tools/list at the top of every loop so list_changed
    notifications surface new tools to the model on the next turn
    (fixes the gated-session case: begin_session reveals the full
    upstream tool set, next round's inference sees all of them).
  - OpenAI-compatible inference via process.env.AGENT_LLM_BASE_URL
    — points at LiteLLM or vLLM directly.
  - Graceful failure: broken tool calls are serialized back into the
    conversation as the tool's response, agent keeps going.
  - maxIterations cap stops runaway loops; hitIterationLimit surfaces
    truncation in the result.
  - Structural `McpLike` / `LlmLike` interfaces keep the loop testable
    without booting real SDKs.

CLI (src/cli.ts):
  mcpctl-agent run "<prompt>" \
    --model qwen3-thinking --project sre \
    [--system "..."] [--max-iterations N] [-o text|json] [--verbose]
  Env fallbacks: AGENT_MCP_URL, AGENT_MCP_TOKEN,
                 AGENT_LLM_BASE_URL, AGENT_LLM_API_KEY, AGENT_MODEL

Tests (7 cases):
  - direct answer (no tool call) → ok
  - single-round tool call + synthesis → message history correct
  - list_changed refresh: tools/list called at startup + after each
    round → next inference sees newly-exposed tools
  - maxIterations cap → hitIterationLimit flag set
  - failing tool → error serialized into conversation, agent recovers
  - systemPrompt prepended
  - mcp.close() runs even when loop throws (finally-block guarantee)

End-to-end verified against live cluster:
  Round 1: sees 1 tool (begin_session) → calls it
  Round 2: sees 115 tools (gate opened) → calls aws-docs/search_documentation
  Final: model synthesizes answer
  — LiteLLM's chat UI cannot do this today; this loop does.

Still to do (follow-up PRs):
  - Wire into mcpctl binary as `mcpctl agent run ...`
  - Docker image + Pulumi deploy for a long-running HTTP service mode
  - Minimal chat UI (HTMX or plain fetch)
  - Streaming responses

 ### Deploy-time steps still owed (outside this repo)
 
-- **Pulumi (`../kubernetes-deployment`, stack `homelab`)** — add a `Deployment` named `mcplocal` in ns `mcpctl` pointing at the new image, a `Service` named `mcp` (port 3200→80), an `Ingress` for `mcp.ad.itaz.eu` with TLS via the existing cluster-issuer, a PVC `mcplocal-cache` (10Gi RWO), a Secret `mcplocal-env` with `MCPLOCAL_MCPD_URL` + `MCPLOCAL_MCPD_TOKEN`, and a NetworkPolicy mirroring mcpd's. `fulldeploy.sh` already runs `pulumi preview` first and halts on drift.
-- **mcplocal's own identity** — recommend minting a dedicated `ServiceAccount:mcplocal-http` subject in mcpd with a non-expiring session token and putting it in `MCPLOCAL_MCPD_TOKEN`. The current session-minting path expires after 30d.
+- **Pulumi (`../kubernetes-deployment`, stack `homelab`)** — add a `Deployment` named `mcplocal` in ns `mcpctl` pointing at `10.0.0.194:3012/michal/mcplocal:latest` (internal registry), a `Service` named `mcp` (port 3200→80, ClusterIP), an `Ingress` for `mcp.ad.itaz.eu` with TLS via the existing cluster-issuer, a PVC `mcplocal-cache` (10Gi RWO, mounted `/var/lib/mcplocal/cache`), and a NetworkPolicy mirroring mcpd's. Required env: **just `MCPLOCAL_MCPD_URL`** (point at `http://mcpd.mcpctl.svc.cluster.local:3100`). Optionally `MCPLOCAL_TOKEN_POSITIVE_TTL_MS` / `MCPLOCAL_TOKEN_NEGATIVE_TTL_MS` for stricter revocation. `fulldeploy.sh` already runs `pulumi preview` first and halts on drift.
+- **No pod-level secret required** (revised from earlier draft) — the pod has no persistent identity to mcpd. Every inbound `Authorization: Bearer mcpctl_pat_…` is forwarded verbatim to mcpd, and mcpd's auth middleware resolves the McpToken principal. This eliminates the original `MCPLOCAL_MCPD_TOKEN` secret and its rotation story. Trade-off: a token with `--rbac=empty` can't read `/api/v1/projects/:name/servers`, but it also can't meaningfully serve MCP, so this is the right failure mode. See `src/mcplocal/src/serve.ts` header comment.
+- **LLM provider config** — if any project served by this pod is `gated: true`, mount your `~/.mcpctl/config.json` as a ConfigMap at `/root/.mcpctl/config.json`. Ungated projects (proxyModel `content-pipeline` or no LLM-driven stages) need nothing.

+/**
+ * MCP-aware chat agent loop.
+ *
+ * Correct where LiteLLM's integration is broken:
+ *   - Uses `@modelcontextprotocol/sdk`'s `StreamableHTTPClientTransport`, which
+ *     preserves `Mcp-Session-Id` across requests automatically.
+ *   - Honors `notifications/tools/list_changed`: after every tool-call round we
+ *     re-fetch the tool list before the next model inference, so an MCP server
+ *     that reveals new tools mid-session (gated sessions, auto-install) shows
+ *     them to the model on the next turn.
+ *
+ * Inference goes through an OpenAI-compatible endpoint (LiteLLM at
+ * http://litellm…:4000/v1 in this repo's deployment; vLLM works too). That
+ * keeps LiteLLM doing its actual job — model routing — and strips it of the
+ * MCP role it was failing at.
