Port upstream 0.55.0: retry Alibaba empty usage

[Finesssee]

Summary

• port upstream CodexBar v0.55.0 Alibaba Personal usage retry behavior from fix(alibaba): tolerate the Personal usage gateway's empty-Success responses steipete/CodexBar#3128
• recognize successful gateway envelopes that temporarily omit rolling usage windows
• retry the usage call up to three times with a bounded delay, then surface a softer temporary-unavailable error instead of a hard parse failure
• preserve existing subscription/quota enrichment and last-good-card semantics

Upstream evidence

• target release: v0.55.0
• upstream commit: 961d7fd10 / fix(alibaba): tolerate the Personal usage gateway's empty-Success responses steipete/CodexBar#3128

Validation

• C:/Users/mac/.cargo/bin/cargo.exe test -p codexbar alibabatokenplan -> 15 passed
• focused rustfmt on rust/src/providers/alibabatokenplan/personal.rs
• git diff --check -> pass

Scope

Isolated provider resilience port. No UI, version bump, or unrelated provider changes.

Thermo-nuclear review

No material code-quality findings. The retry is bounded, its transient condition is isolated in a pure classifier, and subscription/quota metadata is fetched once outside the retry loop rather than duplicating unrelated work.

Verdict: APPROVED.
