v3.7.0

This release stops a local video being uploaded once per player action,
makes the interface report what actually happened instead of assuming success,
and fixes two GUI Modal actions that opened a second window and hung forever.
It also adds upload cancellation, double-tap seeking, a Modal log source in
the GUI, and quiets a large amount of misleading ERROR noise in the host logs.
It has no breaking changes

Added

• Frontend → An in-flight upload can be cancelled from the task tray, which
  stops the transfer and drops the row rather than leaving it to finish

• Frontend → Double-tapping the left or right side of the player skips 5
  seconds, matching the arrow keys

• Launcher → The GUI Logs panel reads the Modal-hosted app's logs as
  well as the local Docker Compose stack, chosen with a new Source control,
  with the same tail and follow controls

Fixed

• Frontend → Running two player actions on the same device video uploaded
  the whole file twice. Clicking Generate SRT and To MP4 on one video sent it
  in full on each action and left two profile files sharing a name. An action
  started while an upload is still running now joins that upload instead of
  beginning its own

• Frontend → A player action on a file that had since been deleted reported
  success while the server rejected it, and no task ever appeared. Actions now
  wait for the result and report the real outcome, naming a deleted file rather
  than failing silently

• Frontend → A profile video deleted while it was loaded showed the
  Convert To Play prompt, which could never succeed. A deleted file is now told
  apart from a container the browser cannot decode, and clears the player

• Frontend → Deleting a file left the jobs it removed on the tasks
  dashboard, where deleting them failed with a not-found error that could not be
  cleared. Those jobs are dropped as the file is deleted, and any task that is
  already gone server-side clears instead of erroring. Transcripts and clips are
  refreshed the same way

• Frontend → On iOS a recording's audio slider never moved and its length
  showed as 0:00, because a browser recording carries no duration until it has
  been read in full. The duration is now picked up when it becomes known

• Frontend → On iOS the file dialog stopped responding after a few
  uploads. Picking the same file twice raised no event, and each preview held its
  audio in memory for the rest of the session, so repeated picks exhausted the
  browser. File inputs now reset between picks and previews are released once
  nothing shows them

• Launcher → Down and Download Data in the GUI's Modal Host panel
  opened a second application window and hung indefinitely. The packaged app
  embeds Python, so the modal CLI could not be run the way those two actions
  ran it. Download Data now streams the volume directly and Down stops the app
  in-process, so neither spawns anything

• Launcher → The Modal Host panel's mode pills kept whatever was true
  when the panel first opened, so a change made in Settings was not reflected on
  returning to it. They are re-read on every visit, as the Dashboard already did

• CLI → mirumoji modal logs --tail accepted counts the modal CLI
  rejects, surfacing its raw usage text. It is bounded to the accepted range, also
  takes -t, and states that it does not apply with --follow

• Server → Video conversions, saved clips and Anki exports were mirrored
  to the Modal volume repeatedly while they were still being written, re-copying
  the same output several times over. Each is now written aside and moved into
  place when finished, so it is copied once

• Server → Ordinary outcomes were logged as failures. A stale reference
  from the interface produced a database ERROR and a full traceback on every
  attempt, burying real problems. Only genuine failures are logged that way now

• Server → Deleting a task that was already gone failed instead of
  succeeding, which left the interface unable to clear it. Deleting a task that no
  longer exists now succeeds

• Server → A cancelled upload was recorded as a server failure rather than
  as the deliberate action it is
