Accept historical v8 config paths and request bodies while saving the
latest canonical layout. Preserve comments on scalar updates and keep v0
saves from migrating legacy-only files unnecessarily.
Move shared Codex, Claude, and xAI provider options under upstream so
they apply consistently to OAuth and API-key credentials. Migrate
historical OAuth paths, preserve OAuth-only header scope, and expose the
new upstream management API path.

Closes: #6261

- Defer terminal response event emission until usage frames arrive or the stream ends
- Map `MAX_TOKENS` finish reason to `response.incomplete` status and incomplete output item states
Closes: #6258
- Handle apply_patch custom tool call streaming deltas and snapshots for Responses API translation
- Track and resolve step indexes, function call identities, and error states across stream events
- Propagate apply_patch tool input errors and upstream failure states in stream and non-stream responses
xAI raised the minimum accepted x-grok-client-version on
cli-chat-proxy.grok.com, so every xAI OAuth chat request through the CLI
chat-proxy failed with HTTP 426 ("Your Grok CLI version (0.2.120) is
outdated"). /v1/models is not gated, so discovery looked healthy while
inference was dead.
Bump the pin to the current stable Grok CLI version (1.0.44) and record
the observed server floor in the constant's comment. Both
x-grok-client-version and the derived User-Agent ship from this one
constant.
Regression tests lock three things: the pinned version meets the known
server floor (red against 0.2.120), the two identity headers stay
derived from the same constant, and the per-auth `header:*` custom
header override still wins over the pin - the documented operator
escape hatch when xAI ratchets the floor again.
