feat(pixiv): native app-API client — gallery-dl-parity profile, post-first seams (#129 step 1)

PixivClient mirrors gallery-dl 1.32.5's PixivAppAPI request profile exactly (iOS app headers, OAuth refresh with X-Client-Time/X-Client-Hash, /v1/user/illusts pagination via next_url — whose query string doubles as the resumable page cursor). Post-first seams (post_record_key / post_is_gated / post_meta) + extract_media covering multi-page, single-page, ugoira zip (600x600→1920x1080 swap, frame delays memoized for the post record), and limit_* placeholder gating. No PHPSESSID web fallback: FC holds only the refresh token, same effective coverage as the gallery-dl path.
