fix(ollama): wrap timeout/connection errors so they retry

[dev-ploy]

Summary

• Fix page_generation_failed floods with local LLMs (Ollama): APITimeoutError
  and APIConnectionError are siblings of APIStatusError under
  openai.APIError, so the old catch-only-APIStatusError clause let them escape
  uncaught, skipping the tenacity retry loop entirely and surfacing as
  page_generation_failed in orchestrate.py (run_level → guarded_named).
• Move the Ollama provider onto the shared retry policy
  (provider_should_retry / provider_retry_stop / provider_retry_wait) with a
  3-way exception mapping (RateLimitError → 429, APIStatusError → HTTP status,
  APIError → transient) so transient timeout/connection errors retry while
  non-retryable 4xx (400/401/403/404/405/413/422) fail fast. Same wrapping applied
  to both stream_chat sites.
• Apply the same defensive APIError catch to the other OpenAI-client providers
  (openai, openrouter, deepseek), and warn when a local provider
  (ollama / codex_cli / opencode) runs with --concurrency > 4.

Closes #445

Test Plan

• Tests pass (pytest) — 897 provider + CLI tests green
• Lint passes (ruff check) on all changed files
• Web build passes (npm run build) — N/A, no frontend changes

Additional manual verification against a live Ollama server, across multiple
locally running models:

• Full repowise init --provider ollama --concurrency 6 --coverage 0.5 runs
  against several local models → all pages generated with 0
  page_generation_failed, and the local-provider concurrency warning shown.
• Forced a real APITimeoutError (1 ms client timeout against the live server):
  now wrapped as ProviderError and retried 3× instead of escaping raw.
• New regression tests confirm 401 (auth) and 400 (invalid request) fail on the
  first attempt — no wasted retries.

Checklist

• My code follows the project's code style
• I have added tests for new functionality
• All existing tests still pass
• I have updated documentation if needed
