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.

modes (command, edit, formula, category, export).
Changes:

- Updated draw_command_bar to use app.buffers instead of mode buffer
- Updated grid edit indicator to use buffers HashMap
- Added tests for command mode buffer behavior:
* command_mode_typing_appends_to_buffer
* command_mode_buffer_cleared_on_reentry
