fix(opencode): log timestamps use local datetime instead of UTC ISO string #21328
Description
Description
Locale.timestamp() in `packages/opencode/src/util/locale.ts` is used to format log entry timestamps, but the name is misleading — "timestamp" typically implies a numeric Unix timestamp or a UTC ISO string, not a local datetime string.
The function actually returns local time in `YYYY-MM-DDTHH:mm:ss` format using `getFullYear()`, `getHours()`, etc. (local time methods, not UTC). The naming makes it easy to assume the output is UTC, which causes confusion when reading logs.
Proposed fix: rename `Locale.timestamp()` → `Locale.localDatetime()` to make the intent clear and align with the existing `Locale.datetime()` naming convention in the same namespace.
