release: v3.3.75

v3.3.74 created a fresh account picker inside every buildUploadTasks /
buildUploadTasksFromJobs call, so its in-memory rotation index reset to 0
on each call. That is correct for a one-shot batch (drag-drop N files at
once distributes fine), but it silently no-ops in exactly the pattern the
byse 80-uploads/30-days quota cares about: the folder monitor feeds new
files into a *running* batch one detection at a time via add-jobs-to-batch
(renderer -> add-jobs-to-batch IPC), and per-detection autoStart likewise
fires start-upload per file. Each of those calls rebuilt the picker from
index 0, so account 1 won every single time and the secondary accounts
never received anything.

The rotation cursor now lives outside the picker and survives across calls
and across app restarts (the quota spans a rolling 30-day window, so a
session-only counter would still starve secondaries for users who restart
between small uploads):

- account-rotation.js: createAccountPicker() accepts a seed { indices } map,
  resumes the per-hoster cursor from it, and exposes indices() (the advanced
  cursors) + dirty() (whether any rotation actually happened this call). The
  cursor is a monotonic counter taken mod the current enabled-account count,
  so it keeps wrapping correctly even if an account is later enabled/disabled.
- config-store.js: new top-level rotationCursors map (added to DEFAULTS, read
  back in load() which otherwise reconstructs the result and would drop
  unknown keys) plus a saveRotationCursors() method. The existing
  read-modify-write save() preserves it across unrelated settings/credential
  saves; secret-store never touches it.
- main.js: a module-level _rotationCursors is the authoritative source of
  truth (seeded once from disk on first use, updated synchronously per batch),
  with config as restart-survival backing. makeAccountPicker() seeds the
  picker from it; persistRotation() folds the advance back and flushes to
  config only when dirty. Authoritative in-memory state also closes the
  disk-read race two rapid batches would otherwise hit. Both task builders
  now receive the picker instead of constructing their own.

Composition with failover is unchanged and verified: the picker only chooses
each file's *initial* account and is never called on the failover path. The
pre-job-swap reroutes a task only when that task's own account is in
_failedAccounts, so a dead account's jobs reroute while healthy accounts keep
their rotation share. No double-advance of the cursor.

Tests: account-rotation gains seeded-resume, drip-feed-across-pickers (the
regression), dirty()-semantics, carry-forward, and count-shrink-wrap cases;
config-store gains rotationCursors default, save round-trip, no-clobber, and
credentials-undisturbed cases. Full suite 303/303.
