Refactor formula handling to use a virtual '_Measure' category.
- Formulas now default to targeting '_Measure' if no category is specified.
- '_Measure' items are dynamically computed from existing data items and
formula targets, preventing redundant item storage.
- Updated persistence to handle '_Measure' formulas and items correctly in
Markdown.
- Updated UI and model to use 'effective_item_names' for layout and item
resolution.
- Updated tests to reflect the new '_Measure' behavior.

_Measure is now a virtual category (CategoryKind::VirtualMeasure),
created automatically in Model::new() alongside _Index and _Dim.
Formula targets are added as items automatically by add_formula.
Formula evaluation uses a fixed-point cache: recompute_formulas()
iterates evaluation of all formula cells until values stabilize,
resolving refs through the cache for formula values and raw data
aggregation for non-formula values. This fixes formulas that
reference other measures when hidden dimensions are present.
evaluate_aggregated now checks the formula cache instead of
recursively evaluating formulas, breaking the dependency between
formula evaluation and aggregation.

Clean up formatting and code style across the project.
- Remove unnecessary whitespace and empty lines in `src/model/cell.rs` ,
`src/model/types.rs` , and `src/draw.rs` .
- Reformat long lines and function calls in `src/command/cmd.rs` ,
`src/ui/grid.rs` , and `src/ui/tile_bar.rs` for better readability.
- Consolidate imports and simplify expressions in `src/command/keymap.rs` and
`src/ui/app.rs` .

Refactor GridLayout to use Rc for sharing records and simplify its structure.
This improves performance when cloning the layout and ensures consistent data
access.
- Use Rc<Vec<(CellKey, CellValue)>> for records in GridLayout
- Update with_frozen_records and other methods to handle Rc
- Simplify layout construction and sorting logic

Unifies cell text retrieval and formatting across pivot and records modes.
Introduces `GridLayout::display_text` to centralize how cell content is
resolved, reducing duplication in `GridWidget` and `export_csv`.
Moves formatting logic from `src/ui/grid.rs` to a new dedicated `src/format.rs`
module to improve reusability.

Refactor records mode to use synthetic CellKeys (_Index, _Dim) for all columns,
allowing uniform handling of display values and edits across both pivot and
records modes.
- Introduce `synthetic_record_info` to extract metadata from synthetic keys.
- Update `GridLayout::cell_key` to return synthetic keys in records mode.
- Add `GridLayout::resolve_display` to handle value resolution for synthetic
keys.
- Replace `records_col` and `records_value` in `CmdContext` with a unified
`display_value`.
- Update `EditOrDrill` and `AddRecordRow` to use synthetic key detection.
- Refactor `CommitCellEdit` to use a shared `commit_cell_value` helper.
BREAKING CHANGE: CmdContext fields `records_col` and `records_value` are replaced by
`display_value` .

Add prune_empty feature to hide empty rows/columns in pivot mode.
View gains prune_empty boolean (default false for backward compat).
GridLayout::prune_empty() removes data rows where all columns are
empty and data columns where all rows are empty.
Group headers are preserved if at least one data item survives.
In records mode, pruning is skipped (user drilled in to see all data).
EditOrDrill command updated to check for regular (non-virtual)
categories when determining if a cell is aggregated.

Introduce records-mode drill-down functionality that allows users to
edit individual records without immediately modifying the underlying model.
Key changes:
- Added DrillState struct to hold frozen records snapshot and pending edits
- New effects: StartDrill, ApplyAndClearDrill, SetDrillPendingEdit
- Extended CmdContext with records_col and records_value for records mode
- CommitCellEdit now stages edits in pending_edits when in records mode
- DrillIntoCell captures a snapshot before switching to drill view
- GridLayout supports frozen records for stable view during edits
- GridWidget renders with drill_state for pending edit display
In records mode, edits are staged and only applied to the model when
the user navigates away or commits. This prevents data loss and allows
batch editing of records.

Implement records mode (long-format view) when drilling into aggregated cells.
Key changes:
- DrillIntoCell now creates views with _Index on Row and _Dim on Column
- GridLayout detects records mode and builds a records list instead of
cross-product row/col items
- Added records_display() to render individual cell values in records mode
- GridWidget and CSV export updated to handle records mode rendering
- category_names() now includes virtual categories (_Index, _Dim)
- Tests updated to reflect virtual categories counting toward limits

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.

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

Both functions previously returned Option despite their invariants
guaranteeing a value: active_view always names an existing view
(maintained by new/switch_view/delete_view), and axis_of only returns
None for categories never registered with the view (a programming error).
Callers no longer need to handle the impossible None case, eliminating
~15 match/if-let Option guards across app.rs, dispatch.rs, grid.rs,
tile_bar.rs, and category_panel.rs.
Also adds Model::evaluate_f64 (returns 0.0 for empty cells) and collapses
the double match-on-axis pattern in tile_bar/category_panel into a single
axis_display(Axis) helper.

Previously CellValue had three variants: Number, Text, and Empty.
The Empty variant acted as a null sentinel, but the compiler could not
distinguish between "this is a real value" and "this might be empty".
Code that received a CellValue could use it without checking for Empty,
because there was no type-level enforcement.
Now CellValue has only Number and Text. The absence of a value is
represented as None at every API boundary:
DataStore::get() → Option<&CellValue> (was &CellValue / Empty)
Model::get_cell() → Option<&CellValue> (was &CellValue / Empty)
Model::evaluate() → Option<CellValue> (was CellValue::Empty)
eval_formula() → Option<CellValue> (was CellValue::Empty)
Model gains clear_cell() for explicit key removal; ClearCell dispatch
calls it instead of set_cell(key, CellValue::Empty).
The compiler now forces every caller of evaluate/get_cell to handle
the None case explicitly — accidental use of an empty value as if it
were real is caught at compile time rather than silently computing
wrong results.

Three copies of cross_product existed (grid.rs, app.rs, persistence/mod.rs)
with slightly different signatures. Extracted into GridLayout in
src/view/layout.rs, which is now the single canonical mapping from a View
to a 2-D grid: row/col counts, labels, and cell_key(row, col) → CellKey.
All consumers updated to use GridLayout::new(model, view):
- grid.rs: render_grid, total-row computation, page bar
- persistence/mod.rs: export_csv
- app.rs: move_selection, jump_to_last_row/col, scroll_rows,
search_navigate, selected_cell_key
Also includes two app.rs UI bug fixes that were discovered while
refactoring:
- Ctrl+Arrow tile movement was unreachable (shadowed by plain arrow arms);
moved before plain arrow handlers
- RemoveFormula dispatch now passes target_category (required by the
formula management fix in the previous commit)
GridLayout has 6 unit tests covering counts, label formatting, cell_key
correctness, out-of-bounds, page coord inclusion, and evaluate round-trip.
