A press only started a selection inside the text being edited; on other
type it waited for the release, which placed the caret at the press and
ignored the drag, so the first drag across a word never selected it.
A press on type now starts editing it there (the same code a click used
on release), so the drag selects at once; a plain click still just
places the caret.
Fixes#245.

Builds on the vertical type from #145 (same data, commands and tools).
- Kinsoku (the strict set, horizontal Japanese too): no line starts with a
closing bracket, 、。, a middle dot, colon, !?, the long vowel mark,
iteration marks or small kana; no line ends with an opening bracket.
Hyphenation breaks obey it too.
- Tate-chu-yoko: a run of two or three half-width digits (10月, 第100回)
stands upright across the column as one block one em long, squeezed to
the em when wider; longer numbers stay on their side.
- Upright or on its side by Unicode's Vertical_Orientation: CJK and
symbols upright, marks that need a vertical form on their side when the
font has none; upright glyphs advance at least one em, centred, and turn
about the ideographic em box centre so they sit on the column's centre
line. Point type keeps its anchor on the first column's centre line.
- `vrt2` is no longer requested: its glyphs are already on their side, so
with the layout turning Latin and digits too they came out upside down
(and tate-chu-yoko blocks broke) in fonts that have it, e.g. Hiragino.
- The line→text mapping is one affine (`TextLayout::line_xf`, an exact
quarter turn plus the point-type offset); `logical_point` and
`physical_point` use it. Pixel snapping skips vertical type.
- Tests: kinsoku in both directions, tate-chu-yoko blocks, upright vs
sideways, anchor on the centre line, arrows along columns.

Typing with an input method (the macOS Japanese IME and the like) used to
insert the raw keys (romaji came in as ASCII): egui's Ime events weren't
handled.
- Tools gain `ime_preedit` / `composing` / `ime_caret`; the Type tool lays
the marked text out in place inside its typing session, underlined (the
clause being converted thicker), and commits it through `text_input`.
Character ranges from the IME convert to byte ranges in one place. A
cancelled composition leaves no empty undo step; an empty clear with
nothing marked never deletes the selection.
- The UI sends Text and Ime events to the tool in order, sends IMEOutput
every frame while text is edited (what lets egui-winit enable the IME
and place its candidate window at the caret, or the converting clause),
and holds back keys, Enter/Escape, clipboard, single-key shortcuts and
menu commands (Undo, Cut, Select All… also from the native menu) while
composing. A click, a tool switch or a style change ends the
composition with the marked text kept as typed; on macOS the IME is
told to discard it (NSTextInputContext.discardMarkedText) so it doesn't
come back in the next input.
- Undo during a typing session also ends the Type tool's session, so its
caret and marked text follow the document.
- Tests: tools (char → byte ranges, underlines and candidate position),
engine (compose → commit is one step, cancel leaves no step, a click
commits, Undo mid-composition is safe), ui-egui (synthetic Ime events:
compose, commit, ⌘Z held back, IME output, click and app switch).
Checked by hand on macOS 27 with the Japanese IME (romaji input, convert,
commit, cancel, Undo/Redo after commit, click away, Latin mode, app
switch). Not checked: Windows and Linux IMEs, the web build.
