Subject: [PATCH] fix(core): add bigint to MessagePlaceholder type

Libraries like Zod use `bigint` for validation bounds (e.g.
`minimum: number | bigint` on `ZodTooSmallIssue`). Passing these
values to `t` template literals currently requires wrapping in
`Number()`.

Adding `bigint` to `MessagePlaceholder` allows these values to be
passed directly, consistent with `i18n._()` which already accepts
`Record<string, unknown>`.
