* fix(deepinfra): tag DeepSeek thinking format and use OpenAI video endpoint
Route DeepInfra video generation through the OpenAI-compatible async
/v1/openai/videos endpoint (submit, then poll) with live video-gen tag
discovery, replacing the retired native /v1/inference path; doctor
migrates api.deepinfra.com URLs and the provider fails closed with an
actionable error on retired custom native endpoints without echoing
configured URLs (they may carry credentials).
Tag the deepseek-ai/* family with thinkingFormat "deepseek" so core
strips/recovers reasoning_content and DSML tool-call markup instead of
leaking it into replies, and mark reasoning-tagged models as
reasoning-capable.
Redaction tests assemble credential-shaped fixture URLs from string
pieces so TruffleHog's URI detector does not flag them. Docs describe
the per-surface static defaults with live discovery expanding the
selectable model lists.
* fix(deepinfra): preserve custom video output host
