Final piece of the artist decoupling. (1) Identity-by-source: quick_add_source
resolves the artist by an existing (platform, url) Source first, so a re-add
reuses the artist even after it was renamed (its frozen slug no longer matches
the name) — a slug-based lookup would have duplicated it. (2) Pixiv naming: a new
pixiv source resolves the real display name via the app API (PixivClient
.resolve_display_name → /v1/user/detail) using the stored token, so the artist is
'Kurotsuchi Machi' not '12345678' — and its name-derived slug matches what a
native download produces, unifying them. Falls back to the numeric id when no
token/crypto. ExtensionService gains the crypto seam; the endpoint passes it.

The core writes the post record BEFORE extract_media, but the ugoira frame
delays were only memoized DURING extract_media — so write_post_record never saw
them and ugoira_frames was always empty in the record. Extract a memoized
_ugoira_meta (frames + zip url share ONE /v1/ugoira/metadata call regardless of
order) and inject client.fetch_ugoira_frames into the downloader (mirrors
Patreon's content_fetcher) so write_post_record populates the frames itself.
Zero extra API calls — the fetch is shared/memoized with extract_media. A
recapture now backfills the timings onto existing ugoira posts.

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.
