Accept valid hyphenated time-zone names.

America/Port-au-Prince is a valid IANA zone, but [A-Za-z_]+ rejects its final component. The match fails before Intl.DateTimeFormat can validate the zone. A quota error with this reset hint therefore uses the 15-minute fallback and repeats probes before the stated reset. Allow valid zone punctuation, then add a policy test that expects a reset-derived delay for this zone. (lists.iana.org)

As per coding guidelines, “New code path ≠ test: flag it. Name the specific test that should exist.”

Review comment at @cli/src/lib/spawn-retry.js at line 103:
Update QUOTA_RESET_RE to accept hyphens in IANA time-zone components while
leaving zone validation to Intl.DateTimeFormat. Add a policy test named for the
America/Port-au-Prince reset hint that verifies the delay is derived from the
stated reset rather than using the 15-minute fallback.
