#321 added its own cli.md section 13, so this PR's sections become 14 (pipe
quoting, surplus arguments) and 15 (names the document lacks), with every
citation renumbered. The stale descriptions of the deleted unknown_* helpers in
cli.md, command.md and the test evidence now describe RequireKnown, and section
15 says a refused name stops the rest of a `:` line but not a headless one.

PR #316 review blockers. A cursor fallback (clear-cell, yank, paste,
drill-into-cell) now answers only for coordinates that were omitted, so
`:clear-cell Type/Clothing Month/Feb junk` is refused instead of clearing the
cursor's cell. The unknown-name checks move from `execute` to a RequireKnown
effect run at apply time, so `:create-view Second . switch-view Second` is
accepted as `improvise cmd` accepts it. Also pins that a quoted `.` is an
argument.

The command-line lexer reads |…| as one argument through the shared
unescape_pipe_body, anywhere in a word, so a coordinate can quote each half.
Double quotes stay verbatim. Every registration now declares MaxArgs, and the
registry refuses arguments beyond it, naming them, on both arms.

`improvise cmd` and `improvise script` resolved every command through
`CmdRegistry::parse` — the pure arm, which builds `CursorState::default()`: row
0, col 0, and a grid of zero rows and zero columns. The interactive arm, which
builds `CursorState::from_ctx(ctx)`, was never reached from a script. So every
`Move` and `enter-advance` snapshotted a zeroed cursor at PARSE time, clamped to
(0, 0) and emitted `SetSelected(0, 0)` — worse than a no-op, since it RESETS the
cursor. Nothing could position it, so every cursor-reading command was pinned to
the origin.
Reproduced at a9cad15 on a document with Region on row carrying North, South,
East: `move-selection 2 0 . hide-selected-row-item` and a bare
`hide-selected-row-item` both wrote `hidden: Region/North`. After the fix the
first writes `hidden: Region/East`.
The repair is `parse::segments` + `parse::parse_segment_interactive`, with the
headless loop re-parsing per segment, because command n must see command n-1's
cursor. Line atomicity is preserved by keeping the existing whole-line
`parse_line` as a syntax gate, so a line that parsed before still parses and the
only behavioural change is which cursor the commands see.
Two things the ticket did not predict. The TUI's `:` line had the identical
defect — `ExecuteCommand` also used the pure arm — and is fixed the same way.
And doing that surfaced a second instance of the same shape one level down:
`register_pure` built an interactive arm that refused EMPTY args while its own
pure arm accepted them, so `w` with no path parsed one way and refused the
other, breaking `improvise cmd 'w'` and `:w` the moment either re-parsed
interactively. Both arms are now `parse`.
Evidence: context/test-evidence/cli.md; reasoning: context/code/cli.md section 7.

keymap.rs: the dispatch/registry-vs-table split (this file stays the authority
on it) and the improvise-0hb Sequence-flattening decline, with its three
findings.
cmd/**: the two CommitAndAdvance orderings, CommitSave's mode-change-first,
add_category's deliberate no-coordinate-write, EditOrDrill's mode-agnostic
message choice, the SaveAndQuit and CreateAndSwitchView declines, and fit.rs's
whole module doc including the measured wasm bundle cost.
crates/improvise-command now reports no comment run over two lines.

Command layer + semantic App state move below the TUI: command/ (cmd,
keymap, parse, key), ui/{app,effect,cat_tree}.rs, and the pure viewport
helpers now live in crates/improvise-command, which depends on core +
formula + io and provably not on ratatui/crossterm (cargo tree clean).
The root crate remains the TUI binary and re-exports improvise_command
under the old crate::command / crate::ui::{app,effect,cat_tree} paths,
so widgets, draw.rs, and main.rs are unchanged. App moves whole (per
the improvise-ltq design note) rather than splitting an AppState out —
its fields are all command-safe after the key/color decoupling.
