Problem:
`u_undo_and_forget()` and `u_forget_unchanged()` do similar undo-tree
surgery: unlink a header, promote the alt branch it displaced.
Solution:
Extract common logic to `u_forget_header()`.
Bonus:
- The `:undo!` copy now fixes `b_u_oldhead`, so after forgetting a root
header, its alt branch is still listed by `undotree()`.
- Freeing can no longer unlink the promoted branch: `uh_alt_prev` is
cleared first. The old code relied on the forgotten header being the
first sibling.

Problem:
`inoremap <Esc> <Esc>l` starts in insert-mode and ends in normal-mode
("l"). Its normal-mode "l" is not captured as a CmdAtom (and thus
doesn't cascade to multicursors in follow-mode).
Analysis:
CmdFrames only delineate in Normal/Visual/Op-pending (i.e. the
`MODE_NORMAL` modes), so a mapping resolved in Insert, Cmdline or
Terminal mode does not start a `composite`, then the mapping "tail" is
lost.
Solution:
Start a "deferred" `composite` if state is not `MODE_NORMAL`, instead of
skipping it entirely.

Problem:
A mapping that ends mid-operation (`nnoremap ,D d`) emits a content-free
"mapping" atom plus a `pending` field, and the "continuation" motion
arrives as a sibling atom. Consumers must stitch the two together (which
has broken cases, e.g. Insert-opening mappings (",i") lose their session
entirely).
- ",i": the session atom is dropped bc the mapping RHS is consumed
before the session starts (typebuf_maplen()==0), so
atom_is_user_input()=false.
- ":normal"-in-opfunc: the opfunc internal "v..y" session (a) became
kVatomTyped just because the deferred composite was open, masking the
real operator capture via atom_captures, and (b) its nested frames
re-derived the outer redo.
- "Motion" based on `moved=true`, has false negatives.
- `CmdAtom.remap` is unnecessary, and clutters the docs/usage.
Solution:
- Introduce `frame_id` to identify CmdFrames.
- Classify `type=motion` better, via `NV_MOTION` flag on the `nv_cmds` table.
- Drop `CmdAtom.pending`, `CmdAtom.remap`.
- Defer atom_composite_end() at the clock edge while an operator is
pending, Visual is active, or `restart_edit` is set: the composite
keeps collecting, so the continuation is captured in the mapping atom.
- ",i": Now an open composite counts as user input.
- ":normal"-in-opfunc: Now handled correctly.
- `remap` is now decided by `composite.payload || 0 subatoms`.
atom_payload_mark() records the read the resolution never captures.
- `toplevel` is now decided by `CmdFrame.parent == NULL`.

Problem:
- Dot-repeat of a Visual selection prepared by a `<Cmd>` mapping,
results in E1255 and leaves Visual mode active.
- Visual-mode capture is implemented as a second, parallel "capture
engine": it re-composes a CmdSpec from cmdarg_T per key and decides
replayability from its own table of "void" key classes.
Solution:
- Model nested `normal_execute()` as a `CmdFrame` stack,
instead of a single module-scoped `stage`.
- Capture `<Cmd>` ":norm …" commands as subatoms from its nested frames.
- Produce every command exactly once; atom_push_raw() routes the atom to
the Visual composite while a selection is open, like it already does
for mapping composites.
- `v/pat<CR>d` is now repeatable and cascades.

Problem:
There is no unified notion of a "user action".
Vim processes input by one-char-at-a-time, and mostly throws away any
hints it might gather about the user's action, with one exception: it
stores the last _edit_ action (the "redo buffer", encoded as
unstructured `["x][v][count]body` bytes).
Plugins can only observe individual keys (vim.on_key) and high-level
effects (TextChanged, CursorMoved).
Solution:
- Users can subscribe to `CmdAtom` events to handle any user action.
- Event is deferred; handlers cannot cancel or interfere with user
actions.
- Capture `CmdSpec` from the normal/insert/visual subsystems.
- typeahead/readahead stay unstructured (`buffheader_T`): they are key
streams, not commands.
- the redo/record buffers become `StringBuilder`: fewer
allocations/copies.
- Repurpose the input/redo engine to accept `CmdSpec` objects.
"atom": one repeatable unit of user input, as a resolved (post-mapping)
keysequence plus structured fields. Only user actions, not `:normal`,
API calls, or non-"t" `feedkeys`.
BREAKING: dot-repeat of an Insert session, replays the entire session
including cursor-moves (:help ins-repeat).
BREAKING: dot-repeat of a Visual operation, replays the selection
instead of operating on a fixed-size region.
