fix(picker): keep max_models=0 distinct from unlimited; lock cap semantics

Follow-up to the cap-removal salvage. The contributor guarded the new
unlimited default with `[:max_models] if max_models else ...`, which conflates
max_models=0 (used by slug-only callers that want an empty model list) with
None (unlimited). Tighten to `is not None` at all five slicing sites in
list_authenticated_providers / list_picker_providers, and add a regression test
asserting the three-way contract: None=full, 0=empty, N=first N.

+# Why this matters for cost: every assistant turn resends the entire
+# accumulated conversation (and, on cache-friendly providers, re-reads the
+# cached prefix and pays for the newly-appended turn). A model that issues
+# one tool call per turn multiplies the number of round-trips — and therefore
+# the resent context — for any task that needs several independent reads,
+# searches, or safe lookups. Batching independent calls into a single
+# assistant response collapses N turns into one, cutting both latency and the
+# resent-context cost that compounds over a long conversation.
+#
+# The hermes-agent runtime already executes a batch of tool calls
+# concurrently when they are independent (read-only tools always; path-scoped
+# file ops when their targets don't overlap — see
+# run_agent._execute_tool_calls / tool_dispatch_helpers). The missing piece
+# was telling the *model* to emit those calls together in the first place.
+# Until now the only batching steer in the prompt lived in
+# GOOGLE_MODEL_OPERATIONAL_GUIDANCE — Gemini/Gemma got it, every other model
+# got nothing. This block makes the steer universal; the now-redundant
+# Google-only bullet has been dropped so no model receives it twice.

+"""Nous Portal terminal-billing HTTP client (Phase 2b).
+
+Thin, fail-loud client for the four ``/api/billing/*`` endpoints the terminal
+billing screens drive. Companion to ``hermes_cli/nous_account.py`` (which owns
+read-only entitlement/balance) — this module owns the *write* side: buy credits,
+poll a charge, configure auto-reload.
+
+Design rules:
+
+- **Money is decimal, never float.** The server emits decimal STRINGS
+  (``"142.5"`` — not fixed 2dp). We parse with :class:`decimal.Decimal` and never
+  round-trip through float.
+- **This client raises typed exceptions; it does NOT fail open.** Fail-open is the
+  *caller's* job (the ``agent/billing_view.py`` builders) so each surface can
+  decide how to degrade. A raw network/HTTP error here surfaces as
+  :class:`BillingError` (or a subclass) carrying the parsed server ``error`` code,
+  HTTP status, ``portalUrl`` deep-link, and ``retry_after``.
+- **Auth** = the OAuth bearer JWT Hermes already holds for inference
+  (``get_provider_auth_state("nous")["access_token"]``). No API-key auth on these.
+- **Portal base URL** resolves with the same precedence as the device-flow login
+  (``auth.py``): ``HERMES_PORTAL_BASE_URL`` → ``NOUS_PORTAL_BASE_URL`` → the
+  stored auth-state ``portal_base_url`` → the registry default. This is how the
+  E2E run points the client at a preview deployment with zero code change.

+source: https://dev.epicgames.com/documentation/unreal-engine/unreal-mcp-in-unreal-editor
+
+# Epic's official "Unreal MCP" plugin (internal id ModelContextProtocol)
+# embeds an MCP server inside the running Unreal Editor process and serves it
+# over local HTTP. There is nothing to install on the Hermes side — the user
+# enables the plugin in-editor and the server binds to 127.0.0.1. Hermes's
+# MCP client just connects to the URL.
+#
+# Default bind is http://127.0.0.1:8000/mcp (port + path are configurable in
+# Editor Preferences > General > Model Context Protocol). If you change the
+# port/path in-editor, edit the url in mcp_servers.unreal-engine afterward.

+# remote use). Nothing to prompt for.

+# Tool selection at install time:
+# The plugin advertises engine tools (spawn actors, configure lighting, create
+# material instances, inspect Slate widgets, run automation tests) and is
+# user-extensible, so the exact surface depends on the project's enabled
+# toolsets. Leave default_enabled unset — the install-time probe lists whatever
+# the live editor exposes and pre-checks all of it; users prune from there.

+  This entry connects to Epic's official Unreal MCP plugin, which runs INSIDE
+  the Unreal Editor. Before Hermes can connect:
+
+    1. Open your project in Unreal Editor 5.8+.
+    2. Edit > Plugins, search "Unreal MCP", enable it, restart the editor
+       (the Toolset Registry dependency enables automatically).
+    3. Edit > Editor Preferences > General > Model Context Protocol, turn on
+       "Auto Start Server" (or run `ModelContextProtocol.StartServer` in the
+       editor console). It binds to http://127.0.0.1:8000/mcp by default.
+
+  Start Hermes AFTER the editor's server is running so the tools are probed.
+  If you changed the port or URL path in Editor Preferences, update the url in
+  mcp_servers.unreal-engine to match.
+
+  Status: Epic ships this as EXPERIMENTAL. The server runs Tool calls serially
+  on the engine game thread — avoid issuing overlapping calls.
+
+  Re-run the tool checklist any time with:

-  Raft gateway adapter for Hermes Agent.
-  Connects to a Raft workspace as an external agent via a local
-  wake-channel bridge. The adapter starts a loopback HTTP endpoint
-  that receives content-free wake hints from the bridge, then
-  injects them into the Hermes gateway session pipeline. The agent
-  reads and sends messages through the Raft CLI — the adapter never
-  touches message bodies or delivery cursors.
