Discord was the last focus platform still on gallery-dl. This adds the native
path, mirrored from gallery-dl 1.32.13's discord extractor:
- discord_client: API v10 with the user token and gallery-dl's request
profile (dated Firefox UA, Referer). Walks a server, category, forum,
channel or thread in gallery-dl's order and pages each channel newest-first.
Files are attachments, then embeds, then forwards, numbered across the
message. The resume cursor is <channel>:<before>. Text-only messages are
not posts, since gallery-dl never made them.
- discord_downloader: gallery-dl's on-disk layout, cleaned the way it cleans
names on Linux (only `/` and control characters change), so existing files
are skipped_disk rather than fetched again. Sidecars carry identity only.
The message record keeps gallery-dl's keys, so parse_sidecar,
derive_post_url and the drop grouping read it unchanged.
- The ledger keys on the attachment id (or a hash of an embed's URL path),
not the file's position, which an edit can renumber. Migration 0111.
- DiscordIngester: token auth, body canary off (files-only drops are
normal). Registered as native, verified by token, and serialised
per-platform, since every source shares one user token.
- ingest_core: optional `skip_feed` client seam (#4413). A tick's early-out
on a multi-channel source now ends the quiet channel, not the whole walk.
Clients without the seam behave as before.
