feat(auth): same-provider credential pools with rotation, custom endpoint support, and interactive CLI (#2647)
* feat(auth): add same-provider credential pools and rotation UX

Add same-provider credential pooling so Hermes can rotate across
multiple credentials for a single provider, recover from exhausted
credentials without jumping providers immediately, and configure
that behavior directly in hermes setup.

- agent/credential_pool.py: persisted per-provider credential pools
- hermes auth add/list/remove/reset CLI commands
- 429/402/401 recovery with pool rotation in run_agent.py
- Setup wizard integration for pool strategy configuration
- Auto-seeding from env vars and existing OAuth state

* fix(tests): prevent pool auto-seeding from host env in credential pool tests

Tests for non-pool Anthropic paths and auth remove were failing when
host env vars (ANTHROPIC_API_KEY) or file-backed OAuth credentials
were present. The pool auto-seeding picked these up, causing unexpected
pool entries in tests.

- Mock _select_pool_entry in auxiliary_client OAuth flag tests
- Clear Anthropic env vars and mock _seed_from_singletons in auth remove test

* feat(auth): add thread safety, least_used strategy, and request counting

- Add threading.Lock to CredentialPool for gateway thread safety
  (concurrent requests from multiple gateway sessions could race on
  pool state mutations without this)
- Add 'least_used' rotation strategy that selects the credential
  with the lowest request_count, distributing load more evenly
- Add request_count field to PooledCredential for usage tracking
- Add mark_used() method to increment per-credential request counts
- Wrap select(), mark_exhausted_and_rotate(), and try_refresh_current()
  with lock acquisition
- Add tests: least_used selection, mark_used counting, concurrent
  thread safety (4 threads × 20 selects with no corruption)

* feat(auth): add interactive mode for bare 'hermes auth' command

When 'hermes auth' is called without a subcommand, it now launches an
interactive wizard that:

1. Shows full credential pool status across all providers
2. Offers a menu: add, remove, reset cooldowns, set strategy
3. For OAuth-capable providers (anthropic, nous, openai-codex), the
   add flow explicitly asks 'API key or OAuth login?' — making it
   clear that both auth types are supported for the same provider
4. Strategy picker shows all 4 options (fill_first, round_robin,
   least_used, random) with the current selection marked
5. Remove flow shows entries with indices for easy selection

The subcommand paths (hermes auth add/list/remove/reset) still work
exactly as before for scripted/non-interactive use.

* fix(tests): update runtime_provider tests for config.yaml source of truth (#4165)

Tests were using OPENAI_BASE_URL env var which is no longer consulted
after #4165. Updated to use model config (provider, base_url, api_key)
which is the new single source of truth for custom endpoint URLs.

* feat(auth): support custom endpoint credential pools keyed by provider name

Custom OpenAI-compatible endpoints all share provider='custom', making
the provider-keyed pool useless. Now pools for custom endpoints are
keyed by 'custom:<normalized_name>' where the name comes from the
custom_providers config list (auto-generated from URL hostname).

- Pool key format: 'custom:together.ai', 'custom:local-(localhost:8080)'
- load_pool('custom:name') seeds from custom_providers api_key AND
  model.api_key when base_url matches
- hermes auth add/list now shows custom endpoints alongside registry
  providers
- _resolve_openrouter_runtime and _resolve_named_custom_runtime check
  pool before falling back to single config key
- 6 new tests covering custom pool keying, seeding, and listing

* docs: add Excalidraw diagram of full credential pool flow

Comprehensive architecture diagram showing:
- Credential sources (env vars, auth.json OAuth, config.yaml, CLI)
- Pool storage and auto-seeding
- Runtime resolution paths (registry, custom, OpenRouter)
- Error recovery (429 retry-then-rotate, 402 immediate, 401 refresh)
- CLI management commands and strategy configuration

Open at: https://excalidraw.com/#json=2Ycqhqpi6f12E_3ITyiwh,c7u9jSt5BwrmiVzHGbm87g

* fix(tests): update setup wizard pool tests for unified select_provider_and_model flow

The setup wizard now delegates to select_provider_and_model() instead
of using its own prompt_choice-based provider picker. Tests needed:
- Mock select_provider_and_model as no-op (provider pre-written to config)
- Call _stub_tts BEFORE custom prompt_choice mock (it overwrites it)
- Pre-write model.provider to config so the pool step is reached

* docs: add comprehensive credential pool documentation

- New page: website/docs/user-guide/features/credential-pools.md
  Full guide covering quick start, CLI commands, rotation strategies,
  error recovery, custom endpoint pools, auto-discovery, thread safety,
  architecture, and storage format.
- Updated fallback-providers.md to reference credential pools as the
  first layer of resilience (same-provider rotation before cross-provider)
- Added hermes auth to CLI commands reference with usage examples
- Added credential_pool_strategies to configuration guide

* chore: remove excalidraw diagram from repo (external link only)

* refactor: simplify credential pool code — extract helpers, collapse extras, dedup patterns

- _load_config_safe(): replace 4 identical try/except/import blocks
- _iter_custom_providers(): shared generator for custom provider iteration
- PooledCredential.extra dict: collapse 11 round-trip-only fields
  (token_type, scope, client_id, portal_base_url, obtained_at,
  expires_in, agent_key_id, agent_key_expires_in, agent_key_reused,
  agent_key_obtained_at, tls) into a single extra dict with
  __getattr__ for backward-compatible access
- _available_entries(): shared exhaustion-check between select and peek
- Dedup anthropic OAuth seeding (hermes_pkce + claude_code identical)
- SimpleNamespace replaces class _Args boilerplate in auth_commands
- _try_resolve_from_custom_pool(): shared pool-check in runtime_provider

Net -17 lines. All 383 targeted tests pass.
