feat(provider): surface config errors + improve provider/log diagnostics

Help users (esp. on Windows) understand why a third-party provider was not
imported, and make upstream/log diagnostics easier to collect.

Provider config errors (stage 1):
- Capture JsonError/InvalidError per global config file into a ConfigError
  collector instead of letting one bad file zero out the whole global config
  (orElseSucceed used to swallow it); expose via Config.getErrors().
- Add optional `errors` to Provider.ListResult + ProviderConfigError schema;
  provider list handler returns them. Regenerate SDK types.
- Render config errors in Settings -> Providers -> Connected providers with a
  danger tag and JSON/schema reason + message. i18n across all locales.

Upstream error logging (executor.ts):
- providerMessage now includes host + requestId + original upstream body so
  relay-gateway errors (e.g. HTTP 429) are attributable at a glance.

Log export diagnostics (CLI + desktop):
- New `deepagent-code debug logs` command (--since, --out) bundling the real
  log dir (~/.deepagent/code/log) for CLI/WSL/headless users.
- Fix serverLogRoots() so one-click export actually collects the real log dir
  (root cause of Windows users not finding logs); parameterize the time
  window and let users pick a save path. Add command-palette entries + i18n.
