Formulas accept B:B / A:C / $B:$B and 1:1 / 2:5 / $3:$3, also qualified
(Umsatz!B:B, Umsatz::1:1, 'Blatt 2'!Kosten::A:C). The open end is clamped
to the table's current size wherever cells are read (evaluation, the
dependency graph, SETVALUE targets, FOR sources), and typing past the
table's end now rebuilds the workbook so such a reference covers the new
cells. The Name Box selects the whole column/row.
The token-level rewriters handle the new shape: copy/fill shifts B:B only
sideways and 1:1 only up/down ($ stays), column insert/delete moves or
#REFs B:B like a range (rows leave it alone, and vice versa), and a table
rename rewrites its qualifier.
Also fixes renaming a table referenced with a quoted name ('Tabelle 1'!B2):
the rewriter replaced only as many characters as the unquoted name has,
leaving a stray quote (=Daten1'!B2).

Beim Tippen eines Funktionsnamens (nach "=", einem Operator, "(" oder
";" -- nicht bei einem Zellbezug wie A1) zeigt sowohl die Formelleiste
als auch der In-Zellen-Editor jetzt ein Dropdown mit passenden
eingebauten UND eigenen Funktionen samt Kurzsignatur. ↑/↓ navigieren,
Tab/Enter/Klick übernehmen (fügt "NAME(" ein), Esc schließt nur das
Dropdown, ohne die Bearbeitung abzubrechen.
- engine/refs.ts: neue reine Funktion currentIdentifierAtCaret() --
strukturell wie das schon vorhandene cycleReferenceLocks (=
abstreifen, tokenize, am Cursor nachsehen), aber nur der Text bis
zum Cursor wird tokenisiert und nur das letzte Token zählt; ein
IDENT, das bis an den Cursor reicht und nicht wie ein Zellbezug
aussieht, ist der Funktionsname. tokenize() hängt ein EOF-Token an
-- muss beim Suchen des "letzten Tokens" herausgefiltert werden
(von den eigenen Tests aufgedeckt).
- engine/functions.ts: BUILTIN_SIGNATURES (Name -> Kurzsignatur je
eingebauter Funktion), gegen FUNCTIONS' Keys testabgesichert, damit
eine künftige neue Funktion ohne Eintrag hier nicht still im
Dropdown fehlt.
- store/document.ts: functionSuggestions(prefix) kombiniert eingebaute
+ dokumenteigene Funktionen, case-insensitiv gefiltert, sortiert.
- composables/useFormulaAutocomplete.ts: pro Editor-Instanz eigener
State (suggestions/activeIndex), orchestriert die drei Bausteine
oben; die Übernahme eines Vorschlags läuft über dieselbe
replace(start,end,value)-Mechanik, die Point-Mode für den Bezug-
Einfügeklick schon nutzt -- keine neue Einfüge-Infrastruktur nötig.
- components/FormulaSuggest.vue: geteiltes, rein präsentationelles
Dropdown (position:absolute; top:100% relativ zum Editor-Wrapper,
kein Caret-Pixel-Tracking).
- FormulaBar.vue + TableGrid.vue: gleiches Einbindungsmuster in
beiden Editoren (Wrapper bekommt position:relative, onInput ruft
autocomplete.update(), onKeydown fängt Pfeiltasten/Tab/Enter/Esc
vor der bestehenden Logik ab, wenn Vorschläge offen sind, onBlur
schließt das Dropdown).
Tests: 13 neue (refs.spec.ts: 7 Fälle für currentIdentifierAtCaret;
functions.spec.ts neu: Signatur-Tabelle deckungsgleich mit FUNCTIONS;
document.spec.ts: functionSuggestions Filter/Mischung/Sortierung).
318 -> 331 Tests, alle grün. vue-tsc/eslint/build sauber. Live per
Playwright verifiziert in Formelleiste UND In-Zellen-Editor: Filterung,
Pfeiltasten-Navigation, Tab-Übernahme, Maus-Klick-Übernahme, Esc
schließt nur das Dropdown, eigene Funktion (MARGE) erscheint neben
eingebauten (MAX) korrekt einsortiert.
READMEs aktualisiert (neuer Abschnitt "Funktions-Autovervollständigung",
Tastaturtabelle, Testliste, Bekannte Grenzen -- dabei eine veraltete
Aussage korrigiert, die Autovervollständigung für benutzerdefinierte
Funktionen noch als "bewusst fehlend" auflistete).

1. In-cell editor width/height ("nur in der Breite der Zelle angezeigt"):
the editor now lives as an overlay (like the clip/fill markers) instead
of inside its <td>, so it can grow past the cell -- width first, up to
an approximated display-width cap, then wrapping and growing height.
Sized via a hidden mirror element (same font/padding, real DOM
measurement -- a <textarea> can't self-size to content with CSS alone).
2. F4 now cycles every reference a real text selection overlaps, each from
its own lock state, not just the one at the caret -- select a stretch of
formula spanning several references and F4 adjusts all of them at once,
same as Excel. cycleReferenceLock(formula, caret) -> cycleReferenceLocks
(formula, start, end); a collapsed selection (start === end) keeps the
old single-reference caret behaviour. Wired into both the in-cell editor
and the formula bar.
3. Alt+Enter inserts a literal newline in the editor instead of committing
(explicit splice at the caret, not relying on the textarea's native
Enter handling, which isn't consistently reachable for Alt+Enter). A
cell holding a newline displays it wrapped (.cell.multiline) instead of
collapsing to one ellipsised line.
Along the way: a <td>'s own max-height doesn't cap table-row growth in any
browser (a table-layout quirk) -- a wrapped multi-line cell was silently
growing its row past rowH(r), which would have desynced every pixel
position computed from rowH()/rowTop() (the overlays, sticky frozen panes,
the row-resize handle). Fixed by moving cell text into its own block-level
.cell-content child, which *does* respect max-height + overflow:hidden.
Verified interactively against the dev server with Playwright: a long
formula gets a ~300px editor instead of the 104px cell; Alt+Enter produces
a real "\n" that survives commit and displays wrapped, with the row height
unchanged (26px, not the ~40px it grew to before the .cell-content fix);
F4 on a full-formula selection turns every reference absolute in one press
and keeps cycling all of them on repeated presses; existing selection,
copy/paste and fill-handle behaviour all regression-checked clean.

The engine already anticipated $A1/A$1/$A$1 in its grammar comment, but the
lexer had no rule for '$' at all -- any formula using it failed to parse.
- lexer.ts: '$' is now a valid word character, so "$A$1" tokenizes as one
IDENT, same as any other bare word (the lexer still doesn't interpret it,
per its "dumb lexer" design -- the parser/evaluator stay untouched, since
evaluation is purely positional and $ has no effect on a value).
- refs.ts: parseA1()/toA1() now carry colAbs/rowAbs through the $ markers
(backward compatible -- existing {col,row} destructuring is unaffected).
Added cycleReferenceLock() for Excel/Numbers-style F4: relative ->
absolute -> row-locked -> col-locked -> relative, toggling whichever
reference sits at the caret (and the correct side of an A1:B2 range).
- document.ts: shiftFormula() now honors the lock on copy (a locked axis
stays exactly as typed) but not on cut (a moved cell's reference follows
it regardless of $, since cut relocates the cell itself rather than
filling a relative offset).
- TableGrid.vue's inline cell editor and FormulaBar.vue both wire up F4 via
the shared cycleReferenceLock() helper.
- Tests: lexer/parser coverage for $ tokenizing/parsing, a new refs.spec.ts
for parseA1/toA1 round-tripping and the F4 cycle (incl. range side-
picking), and document.spec.ts cases for locked-axis copy vs. cut.
- README.md / src/engine/README.md: documented the $ semantics, F4, and
corrected a couple of now-stale claims (test count, "$ is ignored, there's
no copy/fill", "active cell is always the last-clicked one").
