Pastes are probably the last edit one means to make before the query
should run so it doesn't need to be debounced.
This makes global search much snappier for example when accepting the
history suggestion from the '/' register or pasting a pattern from the
clipboard or a register.
We can track the ranges in the input text that correspond to each column
and use this information during rendering to apply a new theme key that
makes the "active column" stand out. This makes it easier to tell at
a glance which column you're entering.
This fixes the changed files picker when used against a clean worktree
for example. Without it the running indicator does not disappear. It
also simplifies the dynamic query handler's implementation so that it
doesn't need to request a redraw explicitly.

DynamicPicker is a thin wrapper over Picker that holds some additional
state, similar to the old FilePicker type. Like with FilePicker, we want
to fold the two types together, having Picker optionally hold that
extra state.
The DynamicPicker is a little more complicated than FilePicker was
though - it holds a query callback and current query string in state and
provides some debounce for queries using the IdleTimeout event.
We can move all of that state and debounce logic into an AsyncHook
implementation, introduced here as `DynamicQueryHandler`. The hook
receives updates to the primary query and debounces those events so
that once a query has been idle for a short time (275ms) we re-run
the query.
A standard Picker created through `new` for example can be promoted into
a Dynamic picker by chaining the new `with_dynamic_query` function, very
similar to FilePicker's replacement `with_preview`.
The workspace symbol picker has been migrated to the new way of writing
dynamic pickers as an example. The child commit will promote global
search into a dynamic Picker as well.
Now that the picker is defined as a table, we need a way to provide
input for each field in the picker. We introduce a small query syntax
that supports multiple columns without being too verbose. Fields are
specified as `%field pattern`. The default column for a picker doesn't
need the `%field` prefix. The field name may be selected by a prefix
of the field, for example `%p foo.rs` rather than `%path foo.rs`.

`menu::Item` is replaced with column configurations for each picker
which control how a column is displayed and whether it is passed to
nucleo for filtering. (This is used for dynamic pickers so that we can
filter those items with the dynamic picker callback rather than nucleo.)
The picker has a new lucene-like syntax that can be used to filter the
picker only on certain criteria. If a filter is not specified, the text
in the prompt applies to the picker's configured "primary" column.
Adding column configurations for each picker is left for the child
commit.
The picker previously used the IdleTimeout event as a trigger for
syntax-highlighting the currently selected document in the preview pane.
This is a bit ad-hoc now that the event system has landed and we can
refactor towards an AsyncHook (like those used for LSP completion and
signature-help). This should resolve some odd scenarios where the
preview did not highlight because of a race between the idle timeout
and items appearing in the picker.
