feat(stepfun): add step-3.7-flash model (#88082)
* feat(stepfun): add step-3.7-flash model and make it default

* fix(stepfun): set step-3.7-flash cacheRead cost to 0.04

* fix(stepfun): raise step-3.7-flash maxTokens to context limit

Output was artificially capped at 65536; StepFun docs set max_tokens
default to INF, bounded only by the 256K context window. Raise
step-3.7-flash maxTokens to 262144 on both stepfun and stepfun-plan,
matching contextWindow. Per models.dev anomalyco/models.dev#1903.
step-3.5-flash entries unchanged.

* fix(stepfun): zero step-plan step-3.7-flash cost for plan billing

Step Plan endpoint bills per subscription plan, not per token, matching
the sibling stepfun-plan/step-3.5-flash and step-3.5-flash-2603 entries
which already carry zero cost. Standard stepfun/step-3.7-flash keeps its
per-token rate. Per models.dev anomalyco/models.dev#1903, whose step-plan
providers omit cost entirely.

* docs(changelog): note StepFun 3.7 support

* style(stepfun): format provider table

* fix(stepfun): forward reasoning effort

* fix(stepfun): scope reasoning compat to 3.7

* test(stepfun): keep 3.5 reasoning compat unchanged

* fix(stepfun): carry off fallback through agent turns

* fix(stepfun): use documented token limit field

* fix(stepfun): match chat completions contract

* chore(stepfun): keep changelog release-owned
