Removes dead use statements across dispatch, formula, import, model, and
UI modules. Prefixes intentionally unused variables with _ in app.rs,
analyzer.rs, and grid.rs.

When a formula Ref resolves to an item that doesn't exist in any
category, find_item_category returned None and the fallback
unwrap_or(name) used the item name as a category name. The resulting
key still matched the formula target, causing infinite recursion and a
stack overflow. Now returns None immediately via ? so the expression
evaluates to Empty.
Adds unit tests for Model (structure, cell I/O, views), formula
evaluation (arithmetic, WHERE, aggregation, IF), and a full
five-category Region×Product×Channel×Time×Measure integration test.

ImportPipeline holds all data and logic (raw JSON, records, proposals,
model_name, build_model). ImportWizard wraps it with UI-only state
(step, cursor, message). Rename WizardState → WizardStep throughout.
Headless import in dispatch.rs now constructs ImportPipeline directly.

move_selection() only clamped at 0, letting the row/col index go past
the last valid item. Selected_cell_key() would then return None, leaving
the cursor in a phantom position with no selectable cell.
Now clamp both row and col against the actual item count so pressing
Enter on the last row keeps the cursor on that row.

N (from anywhere) or n (in Category panel) opens an inline prompt
to add categories one after another without typing :add-cat each time.
- Yellow border + prompt distinguishes it from item-add (green)
- Enter / Tab adds the category and clears the buffer, staying open
- Esc returns to the category list
- Cursor automatically moves to the newly added category

Two new ways to add multiple items without repeating yourself:
1. :add-items <category> item1 item2 item3 ...
Adds all space-separated items in one command.
2. Category panel quick-add mode (press 'a' or 'o' on a category):
- Opens an inline prompt at the bottom of the panel
- Enter adds the item and clears the buffer — stays open for next entry
- Tab does the same as Enter
- Esc closes and returns to the category list
- The panel border turns green and the title updates to signal add mode
- Item count in the category list updates live as items are added

- Welcome overlay shown when model has no categories, listing common
commands and navigation hints to orient new users
- Vim-style keybindings:
- i / a → Insert mode (edit cell); Esc → Normal
- x → clear cell; yy / p → yank / paste
- G / gg → last / first row; 0 / $ → first / last col
- Ctrl+D / Ctrl+U → half-page scroll
- n / N → next / prev search match
- T → tile-select mode (single key, no Ctrl needed)
- ZZ → save + quit
- F / C / V → toggle panels (no Ctrl needed)
- ? → help (in addition to F1)
- Command mode (:) for vim-style commands:
:q :q! :w [path] :wq ZZ
:import <file.json> :export [path]
:add-cat <name> :add-item <cat> <item>
:formula <cat> <Name=expr> :add-view [name] :help
- Status bar now context-sensitive: shows mode-specific hint text
instead of always showing the same generic shortcuts
- Mode label changed: "Editing" → "INSERT" to match vim convention
- Title bar shows filename in parentheses when model is backed by a file
- Help widget updated with full key reference in two-column layout
