187944615e check both queues when popping answered card
If multiple answers are applied in succession, a newly-due learning card
may be in front of the next main entry.

13519a929c rework various aspects of the test scheduler
- Daily limits are no longer inherited - each deck limits its own
cards, and the selected deck enforces a maximum limit.
- Fetching of review cards now uses a single query, and sorts in advance.
In collections with a large number of overdue cards and decks, this is
faster than iterating over each deck in turn.
- Include interday learning count in review count & review limit, and
allow them to be buried.
- Warn when parent review limit is lower than child deck in deck options.
- Cap the new card limit to the review limit.
- Add option to control whether new card fetching short-circuits.

390a8421aa fix test scheduler undo + implement look-ahead
Instead of using a separate undo queue, the code now defers checking for
newly-due learning cards until the answering stage, and logs the updated
cutoff time as an undoable change, so that any newly-due learning cards
won't appear instead of a new/review card that was just undone.

Queue redo now uses a similar approach to undo, instead of rebuilding the
queues.

9990a10161 drop binary heap in test scheduler
The original rationale was avoiding a possible O(n) insertion if
the learning card was due outside the cutoff, but the increased code
complexity doesn't seem worth it, given that learning cards will
rarely grow above 1000.

Also added a currently-disabled test that demonstrates the current undo
handling behaviour is yielding incorrect counts; that will be reworked
in the next commit, and this change will make that easier.

be994f4102 add support for custom undo steps, and merging multiple actions
Allows add-on authors to define their own label for a group of undoable
operations. For example:

def mark_and_bury(
    *,
    parent: QWidget,
    card_id: CardId,
) -> CollectionOp[OpChanges]:
    def op(col: Collection) -> OpChanges:
        target = col.add_custom_undo_entry("Mark and Bury")
        col.sched.bury_cards([card_id])
        card = col.get_card(card_id)
        col.tags.bulk_add(note_ids=[card.nid], tags="marked")
        return col.merge_undo_entries(target)

    return CollectionOp(parent, op)

The .add_custom_undo_entry() is for adding your own custom actions.
When extending a standard Anki action, instead store `target = 
col.undo_status().last_step` after executing the standard operation.

This started out as a bigger refactor that required a separate
.commit_undoable() call to be run after each operation, instead of
having each operation return changes directly. But that proved to be
somewhat cumbersome in unit tests, and ran the risk of unexpected
behaviour if the caller invoked an operation without remembering to
finalize it.

64ebc32b3d tidy up Rust imports
rustfmt can do this automatically, but only when run with a nightly
toolchain, so it needs to be manually done for now - see rslib/rusfmt.toml

a18bb2af12 add booleans for various screens to OpChanges
The backend knows exactly which op has executed, and it saves us having
to re-implement this logic on each client.

Fixes the browser table refreshing when toggling decks.

dc81a7fed0 use mixed case for abbreviations in Rust code
So, this is fun. Apparently "DeckId" is considered preferable to the
"DeckID" were were using until now, and the latest clippy will start
warning about it. We could of course disable the warning, but probably
better to bite the bullet and switch to the naming that's generally
considered best.

6b0fe4b381 undoable ops now return changes directly; add new *_ops.py files
- Introduced a new transact() method that wraps the return value
in a separate struct that describes the changes that were made.
- Changes are now gathered from the undo log, so we don't need to
guess at what was changed - eg if update_note() is called with identical
note contents, no changes are returned. Card changes will only be set
if cards were actually generated by the update_note() call, and tag
will only be set if a new tag was added.
- mw.perform_op() has been updated to expect the op to return the changes,
or a structure with the changes in it, and it will use them to fire the
change hook, instead of fetching the changes from undo_status(), so there
is no risk of race conditions.
- the various calls to mw.perform_op() have been split into separate
files like card_ops.py. Aside from making the code cleaner, this works
around a rather annoying issue with mypy. Because we run it with
no_strict_optional, mypy is happy to accept an operation that returns None,
despite the type signature saying it requires changes to be returned.
Turning no_strict_optional on for the whole codebase is not practical
at the moment, but we can enable it for individual files.

Still todo:
- The cursor keeps moving back to the start of a field when typing -
we need to ignore the refresh hook when we are the initiator.
- The busy cursor icon should probably be delayed a few hundreds ms.
- Still need to think about a nicer way of handling saveNow()
- op_made_changes(), op_affects_study_queue() might be better embedded
as properties in the object instead

ecea2161e3 dispatch undo operations via enum instead of trait
To coalesce successive note edits into a single undo op we'll need to
be able to get the original Undoable type, which is awkward to do with
a trait object.

49a1970399 note deletion undo; refactoring
- transact() now automatically clears card queues unless an op
opts-out (and currently only AnswerCard does). This means there's no
risk of forgetting to clear the queues in an operation, or when undoing/
redoing
- CollectionOp->UndoableOp
- clear queues when redoing "answer card", instead of clearing redo
when clearing queues

b466f0ce90 rework undo
- use dataclasses for the review/checkpoint undo cases, instead of the
nasty ad-hoc list structure
- expose backend review undo to Python, and hook it into GUI
- redo is not currently exposed on the GUI, and the backend can only
cope with reviews done by the new scheduler at the moment
- the initial undo prototype code was bumping mtime/usn on undo, but
that was not ideal, as it was breaking the queue handling which expected
the mtime to match. The original rationale for bumping mtime/usn was
to avoid problems with syncing, but various operations like removing
a revlog can't be synced anyway - so we just need to ensure we clear the
undo queue prior to syncing

c9eeb91e0a initial work on undoing reviews+burying siblings
- fetch sfld and csum when fetching notes, to make it cheaper
to write them back out unmodified
- make `fields` private, and access it via accessors, so we can
still catch when fields have been mutated without calling
prepare_for_update()
- fix python importing code passing a string in as the checksum
