Create keymap.rs with Keymap struct mapping (mode, key) to Cmd trait
objects. Wire into App::handle_key — keymap dispatch is tried first,
falling through to old handlers for unmigrated bindings. Normal mode
navigation, cell ops, mode switches, and Help mode are keymap-driven.

Define Effect trait in ui/effect.rs with concrete effect structs for
all model mutations, view changes, navigation, and app state updates.
Each effect implements apply(&self, &mut App). Add App::apply_effects
to apply a sequence of effects. No behavior change yet — existing
key handlers still work as before.

Replace JSON command syntax with prefix notation: `word arg1 arg2`.
Multiple commands per line separated by `.`. Coordinate pairs use
`Category/Item`. Quoted strings for multi-word values. set-cell
uses value-first: `set-cell 100 Region/East Measure/Revenue`.

Add key handling for ConfigureDates (space toggle components) and
DefineFormulas (n new, d delete, text input mode) wizard steps.
Render date component toggles, formula list with input area, and
sample formulas derived from detected measures.

Extend FieldProposal with chrono-based date format detection and
configurable component extraction (Year, Month, Quarter). Add
ConfigureDates and DefineFormulas wizard steps to ImportPipeline.
build_model injects derived date categories and parses formula strings.

Categories on the None axis are excluded from the grid and cell keys.
When evaluating cells, values across hidden dimensions are aggregated
using a per-measure function (default SUM). Adds evaluate_aggregated
to Model, none_cats to GridLayout, and 'n' shortcut in TileSelect.

Add row_group_for/col_group_for to GridLayout, replacing inline
backward-search logic. Refactor grid renderer to use col_group_for
instead of pre-filtering col_items. Add gz keybinding for column
group collapse toggle, symmetric with z for rows.

- Use csv crate for robust CSV parsing (handles quoted fields, empty values, \r\n)
- Extend --import command to auto-detect format by file extension (.csv or .json)
- Reuse existing ImportPipeline and analyzer for field type detection
- Categories detected automatically (string fields), measures for numeric fields
- Updated help text and welcome screen to mention CSV support
All 201 tests pass.
Builds out two half-finished view features:
Group collapse:
- AxisEntry enum distinguishes GroupHeader from DataItem on grid axes
- expand_category() emits group headers and filters collapsed items
- Grid renders inline group header rows with ▼/▶ indicator
- `z` keybinding toggles collapse of nearest group above cursor
Hide/show item:
- Restore show_item() (was commented out alongside hide_item)
- Add HideItem / ShowItem commands and dispatch
- `H` keybinding hides the current row item
- `:show-item <cat> <item>` command to restore hidden items
- Restore silenced test assertions for hide/show round-trip

The two tests were previously silenced when item_by_name was removed.
Rewrites them using category.items.get() directly, restoring coverage
of item-name and item-group serialization round-trips.

Removes unused methods (sum_matching, get_mut, item_by_name, item_index,
top_level_groups, is_group_collapsed, show_item) and unused constants
(LABEL_THRESHOLD, MIN_COL_WIDTH).
The sum_matching tests in model.rs were bypassing the formula evaluator
entirely. Replaced them with equivalent tests that call evaluate() against
the existing Total = SUM(Revenue) formula, exercising the real aggregation
code path.
Also fixes a compile error in view.rs prop_tests where View/Axis imports
and a doc comment were incorrectly commented out.
