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.

+# 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

+#
+# The hermes-agent runtime already executes a batch of tool calls

-"""Profile-scoped credential resolution for multi-profile gateway multiplexing.
-
-The multiplexing gateway serves many profiles from one process. Each profile
-has its own ``.env`` with its own provider keys and platform tokens, so we
-**cannot** union them into the process-global ``os.environ`` (that would leak
-profile A's keys to profile B's turns, and to every subprocess spawned with
-``env=dict(os.environ)``).
-
-This module provides a fail-closed, context-local secret scope:
-
-- ``set_secret_scope(mapping)`` installs the active profile's secrets for the
-  current task (a contextvar, so it propagates into the agent's worker thread
-  via ``copy_context()`` exactly like the HERMES_HOME override).
-- ``get_secret(name)`` reads from that scope. When multiplexing is **active**
-  and no scope is set, it RAISES rather than silently falling back to
-  ``os.environ`` — an un-migrated or newly-added call site fails loud at that
-  exact line instead of leaking another profile's value. When multiplexing is
-  **off** (the default), it transparently reads ``os.environ`` so the
-  single-profile gateway and every non-gateway caller behave exactly as before.
-
-Design rationale lives in ``docs/design/multiplexing-gateway.md`` (Workstream A).

+"""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.

+# 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.

+# 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.

+
+Covers:
+- Decimal money parsing/formatting (server emits decimal strings, not 2dp).
+- BillingState payload parsing (role tiering, presets, bounds, sub-structs).
+- Error-code → typed-exception mapping (the live-verified contract matrix).
+- Fail-open builder behavior.
+- Idempotency key generation.
+- Custom-amount validation against bounds + multipleOf 0.01.
+
+No network: HTTP-layer tests drive _raise_for_error directly and monkeypatch the
+request function for the builder.

+and only when its System32 directory is on ``PATH``.  Under PowerShell 7+
+(``pwsh``) -- or any session where ``powershell`` isn't on ``PATH`` -- the

+The fix resolves the PowerShell host executable (preferring the absolute path
