8b2a1d7c1f fix(byse): treat 5xx/gateway upload failures as transient infra, not account faults
A single byse.sx gateway hiccup (HTTP 502 "<!doctype html>..." or a mid-upload
ECONNRESET) was cascading through the whole failover chain and blacklisting every
account for the batch. Root cause: the upload-POST throw sites threw PLAIN errors
with no classification, so a 502 was treated as a GENERIC error -> mark-failed ->
emit('account-failed') -> failover to the next account (which hits the same
gateway) -> repeat until the chain is exhausted, then poison sibling files in the
batch via the blacklist. The screenshots showed exactly this: "Primär ... Fallback
#3" all failing with the same 502. byse did NOT change their API (the upload
contract still matches their docs and was live-probed: GET /upload/server -> POST
{key}+file -> files[0].filecode); these are transient infrastructure failures.

A 5xx gateway error is not an account fault: every account hits the same gateway,
so failing over is pointless and blacklisting is harmful. Fail open instead — retry
the SAME account and, if byse stays down, fail the file cleanly without touching the
account or the rotation cursor.

- upload-manager: _isTransientNetworkError() now honors an explicit err.transientNetwork
  flag (checked before the empty-message guard) and, as a defensive fallback, matches
  /HTTP 5\d\d/, Bad Gateway, Service Unavailable, Gateway Time-out. The flag is made
  authoritative in _isFileRejectedError and _shouldSkipRetryOnAccountError (both return
  early when it is set) so a 5xx whose HTML body happens to contain a rejection/auth
  keyword can never be mis-binned as file/account. The post-rotation retry loop also
  breaks on a transient error (parity with the primary loop) to avoid burning the
  retry budget re-uploading on a fallback.
- hosters: the upload POST throw sites tag err.transientNetwork when statusCode >= 500
  (non-JSON body and non-2xx-with-JSON) and when the 2xx status-envelope carries
  status:500; 401/403/429 stay PLAIN so they remain account errors. The server-lookup
  path (apiGet/getUploadServer) is hardened symmetrically: a 5xx there tags
  transientNetwork and getUploadServer preserves the flag onto its wrapped error, so
  the heuristic shouldRetryServerLookup() can no longer be defeated by a 5xx body that
  contains an auth keyword.
- hosters: fixed a separate real bug surfaced during investigation — _fetchByseFileList
  built the wrong URL https://api.byse.sx/api/file/list (the /api/ prefix is correct
  only for doodstream's doodapi.co host; byse already carries the api. subdomain).
  Live-probed: /api/file/list 302-redirects to the docs page, /file/list returns 200
  JSON. The wrong path made the byse async-recovery poll silently dead (always []),
  removing the safety net that reclaims a large file that registered despite a 502.
  Now https://api.byse.sx/file/list.

ECONNRESET was already transient and is unchanged. doodstream's 2xx empty-form stays
hosterTransient (one attempt, no re-upload). vidmoly/clouddrop use their own uploaders
and are unaffected; doodstream/voe apiKey uploads share uploadFile and correctly
benefit from the same 5xx-is-infra logic.

Deferred follow-up: poll-first-on-5xx dedup (route a 5xx through the now-working
recovery poll before retrying, to reclaim a registered-but-502 file instead of
re-uploading). It does not add new dupe risk vs the prior cascade and a pure 502
means the backend was never reached, so retry-same-account is dupe-safe for it.

Investigated and reviewed by two multi-agent workflows (4-lens investigation with a
synthesized fix spec; 4-lens adversarial review with per-finding verification): no
API drift, 0 confirmed defects. Tests: classifier units (flag-above-message-guard,
5xx-transient, 4xx-stay-account), an end-to-end 502/503/500-envelope tag through
uploadFile, and a 502-retries-same-account-no-cascade integration case. Suite 311/311.

497317dc32 fix(rotation): suspect byse rejections now reach every account instead of dying on the first
Root cause of "4 accounts configured, rotation only ever uses 1-3": byse
returns HTTP 200 + per-file status "Not video file format" for valid MKVs
above an account's size tier (proven from the live rotation log: account
4ha0 accepted 1158 files up to 2.62 GB and deterministically rejected all
6 files >= 2.81 GB with that status, each costing a full ~20 min upload).
The parser tagged this fileRejected, which (a) skipped the 30s recovery
poll that was originally BUILT for this misleading status (guard regression
from "byse skips 30s recovery poll on explicit reject") and (b) made the
upload manager skip rotation entirely - so the remaining accounts were
never tried and the files failed forever. Account selection is
primary-first failover, so a later account only ever runs when every
earlier one is hard-failed or disabled, which matches the reported
"account 4 only gets used when I disable the others".

The fix, layered:
- parseByseResult flags "Not video file format" as err.suspectReject
  (alongside fileRejected). Genuine rejections (Duplicate, too small,
  account-level disk-full) behave exactly as before.
- uploadFile runs the byse recovery poll again for suspect rejections
  (the file often registers asynchronously despite the status), but skips
  it when the caller's file probe says the upload is genuinely not a video
  (new opts.probeIsVideoLike, threaded from the upload manager's probe).
  Poll helpers now swallow an abort during their sleep and return null so
  a cancelled poll surfaces the original error instead of a bare
  AbortError.
- upload-manager: on a suspect rejection of a probe-verified video, the
  file gets ONE attempt on each remaining pool account (new accountPools
  from main.js, refreshed on save-config) - WITHOUT blacklisting the
  rejecting account, which keeps working for smaller files. A per-batch
  size memo (hoster:account -> smallest rejected size) plus a known-good
  account preference prevent re-uploading every following oversized file
  through the whole chain: the second file skips known-limited accounts
  outright and goes straight to the account that took the first one.
  Alternates that fail with a genuine account error (quota/ban/full) are
  marked failed in-batch so no later file burns a multi-GB upload on them;
  deliberately no account-failed emit there, as repointing the hoster-wide
  override would reroute normal-sized files away from a healthy primary.
- Rotation hardening from the adversarial review: the rotated-to retry
  loop now fast-breaks on file-rejected/hoster-transient errors instead of
  burning maxAttempts full uploads, and a file-class error on a rotated
  account no longer blacklists that account (it fails only the file).
  Cancelling mid-alternates or mid-rotation now records the job as
  aborted instead of error (this also stops the batch webhook from firing
  on fully user-cancelled batches). New upload-failure rot-logs are
  guarded against logging user aborts as failures; rotation retries are
  now visible in the rotation log at all (previously failures on a
  rotated-to account were never logged, which is why account 2's death
  was invisible in the support log).
- file-probe: the mpeg-ts signature required only a single leading 0x47
  byte, so GIFs and "G"-prefixed text classified as video and would have
  qualified junk for pool-wide alternate uploads; it now requires TS
  sync-byte periodicity (0x47 at offsets 0/188/376) and the probe head
  read grew from 64 to 512 bytes to make that check possible. GIF gets
  its own non-video signature.

Tests: 9 new/reworked across suspect-reject-alternates.test.js (alternate
walk, no blacklist, memo short-circuit, account-error marking, abort
labeling, probe gating) and byse-reject-recovery.test.js (suspect polls +
recovers, empty poll throws suspectReject, Duplicate still fast-fails,
probe-confirmed non-video skips the poll) plus a TS/GIF probe regression
test. Full suite 276 green.
