fix: extend hostname-match provider detection across remaining call sites

Aslaaen's fix in the original PR covered _detect_api_mode_for_url and the
two openai/xai sites in run_agent.py. This finishes the sweep: the same
substring-match false-positive class (e.g. https://api.openai.com.evil/v1,
https://proxy/api.openai.com/v1, https://api.anthropic.com.example/v1)
existed in eight more call sites, and the hostname helper was duplicated
in two modules.

- utils: add shared base_url_hostname() (single source of truth).
- hermes_cli/runtime_provider, run_agent: drop local duplicates, import
  from utils. Reuse the cached AIAgent._base_url_hostname attribute
  everywhere it's already populated.
- agent/auxiliary_client: switch codex-wrap auto-detect, max_completion_tokens
  gate (auxiliary_max_tokens_param), and custom-endpoint max_tokens kwarg
  selection to hostname equality.
- run_agent: native-anthropic check in the Claude-style model branch
  and in the AIAgent init provider-auto-detect branch.
- agent/model_metadata: Anthropic /v1/models context-length lookup.
- hermes_cli/providers.determine_api_mode: anthropic / openai URL
  heuristics for custom/unknown providers (the /anthropic path-suffix
  convention for third-party gateways is preserved).
- tools/delegate_tool: anthropic detection for delegated subagent
  runtimes.
- hermes_cli/setup, hermes_cli/tools_config: setup-wizard vision-endpoint
  native-OpenAI detection (paired with deduping the repeated check into
  a single is_native_openai boolean per branch).

Tests:
- tests/test_base_url_hostname.py covers the helper directly
  (path-containing-host, host-suffix, trailing dot, port, case).
- tests/hermes_cli/test_determine_api_mode_hostname.py adds the same
  regression class for determine_api_mode, plus a test that the
  /anthropic third-party gateway convention still wins.
