When undo was in macro it couldn't be replayed as it was already in single command executiion. So other commands modified editor and when undo was trying execute those commands didn't yet commit and in UndoManager in Ij there is
```
if (document.getTextLength() != fromLength) throw new UnexpectedUndoException("Unexpected document state");
```
So we have to execute each command separately during macro execution
Update the changelog and the What's New page for the upcoming release.

whatsnew-tbr.html: incrementally added the new langmap feature section
and the new fixes to "polish & fixes", preserving the existing content.

It's two-step process
1. manual run of prepare what's new that will generate html page with blogpost about what's new
2. promote current whatsnew-tbr.html to new version in release pipeline
count(list, expr, ic, start) handled the start index incorrectly:
- Negative start indices (which Vim counts from the end of the list)
were ignored, falling back to counting the whole list.
- An out-of-range start index silently counted the whole list instead
of raising an error.
Vim resolves the start index via list_find(), which supports negative
indices and reports E684 (list index out of range) when the index is
invalid. Match that behavior: normalize negative indices and throw E684
for out-of-range values. The start argument is only applied when
explicitly provided, so count(list, expr) on an empty list still
returns 0 rather than erroring.
Adds regression tests for zero, negative, and out-of-range start indices.

Vim's get(list, idx [, default]) supports negative indices, which count
from the end of the list (e.g. -1 is the last item). IdeaVim used
List.getOrElse(idx) directly, which treats any negative index as
out-of-bounds and returns the default value instead.
Normalize negative indices before lookup, matching the pattern already
used in remove(). Adds regression tests for negative and out-of-range
negative indices.

The digraph consumer is before the char argument consumer, so digraph keys will be processed first. If a key isn't a digraph key, it is ignored and the char argument consumer will process it; the digraph consumer doesn't need to set a fallback argument type and repost the key.
processing escape might be entered from multiple places at once but we don't wont to repeat it.
For example, it might be called from standard esc processing and Rider Escape lookup which results in duplicated text insertion
When user had mapping for key `onUnfinishedMappingSequenceTimeout` executed this key mapping again which resulted in duplicated key in macro. To prevent that we took simillar approach as nvim to not record mapped keystrokes
