fix(api): parse zh-locale usage labels and reset phrases

[waknow]

Problem

The opencode.ai dashboard renders the usage page in the UI locale negotiated from the cookie. With oc_locale=zh the data-slot=usage-label values come back as Chinese (rolling/weekly/monthly usage in Chinese) and the reset phrase as Chinese instead of Resets in.

The SSR scraper in src/api.ts only recognizes the English labels and the English reset phrase, so with a zh-locale cookie:

1. labelToKind matches nothing -> all three windows are dropped
2. fromSSRHTML returns an empty result
3. fetchViaCookie treats empty page as a login redirect and throws UsageError('Usage page parsed empty (cookie expired or invalid?)', 'http302')

Net effect: the chip shows err:http302 even though the cookie is perfectly valid.

Fix

• labelToKind: also recognize the Chinese labels
• reset-time regex: accept both Resets in and the Chinese phrase prefix
• parseDurationToSec: accept Chinese time units, including the counter for 1 month

Also rebuilt lib/ (the checked-in build output) so GitHub/npm installs work without a local build.

Tests

• New zh-locale SSR fixture exercising all three windows with Chinese labels and reset phrases
• New zh duration cases in the parseDurationToSec table

All 48 tests pass (pnpm test), typecheck and build pass.
