Splits the flat 432-line main.rs into four modules so each file has one
clear job: render.rs owns layout constants and drawing primitives,
editor.rs owns EditorTab/EditorState and the side panel, glyph_picker.rs
owns the floating picker dialog with a decoupled (open, glyph) interface,
and main.rs is reduced to AppMode, App, and the frame loop (~150 lines).

- Extract draw_board() to eliminate duplicated board+player render loop in Edit and Play branches
- Extract pos_to_cell() to eliminate duplicated click-to-cell floor math in board and char grid handlers
- Simplify glyph dedup to use Glyph: PartialEq directly instead of manual key tuples
- Merge two identical clicked() handlers in archetype list into one || check
- Remove WHAT-explaining comments

Selecting a different archetype in the editor now updates the active
glyph to that archetype's default_glyph(), keeping the visual preview
in sync with the selected behavior type.

Glyph chooser: a painted preview button in the Palette tab opens a
floating dialog with a board-palette picker, fg/bg color pickers
(egui built-in), and a 16×6 printable ASCII character grid. The
stamped glyph is now independent of the archetype's default.
Side panel: widened to 200 px (resizable), tabbed (Palette / Board /
World), archetype rows show their default glyph cell, list scrolls
after 5 entries, labels use ui.label() for consistent sizing.

Edit mode now wraps the board in a ScrollArea so horizontal/vertical
scroll bars appear when the board is larger than the window. Play mode
keeps the existing player-centered viewport with no scroll bars.

Window size is now fixed (840×524) and independent of map dimensions.
Small maps center in the viewport; maps larger than the viewport keep
the player centered and clamp at board edges so no empty space shows.
Also derives Copy+Clone on Player to enable the per-frame origin calculation.

Documents the replacement of Element with Behavior + Archetype, the
elimination of the per-board element palette, the new map file format
(archetype = "name" instead of passable = bool), the ErrorBlock sentinel,
and the editor mode (AppMode, EditorState, palette panel, click-to-paint).
Also updates "What's not yet implemented" to reflect editor progress and
call out the Object behavior / glyph chooser / file open gaps.

AppMode enum (Play/Edit) gates arrow-key input; a mode toggle in the
menu bar switches between them. Edit mode shows a SidePanel listing the
available archetypes (Empty, Wall, Object); clicking one selects it.
Clicking a board cell in Edit mode stamps it with the selected
archetype's default glyph. Mouse-to-cell conversion mirrors the
rendering origin math so clicks land on the correct cell.

Element is replaced by two types: Behavior (a plain struct of runtime
properties: passable, opaque) and Archetype (an enum of named presets:
Empty, Wall, Object, ErrorBlock). Board.cells changes from Vec<(Glyph,
usize)> to Vec<(Glyph, Archetype)>, eliminating the per-board element
palette. Map files now reference archetypes by name (archetype = "wall")
instead of property bags (passable = false), so the archetype list can
be reordered without breaking saved games. Unknown archetype names
produce an ErrorBlock cell (yellow ? on red) so malformed maps are
immediately visible in-game.

All public types, fields, and functions in game.rs and map_file.rs now
have /// doc comments. main.rs has /// on App and draw_glyph plus inline
comments explaining the input/render pipeline. CLAUDE.md records the
expectation that generated code includes comments.

Documents the player-as-object goal and calls out the four specific
places in the current design (Board.player, player_start, try_move,
main.rs overlay) that will need to change when that's implemented.

Documents the module structure, key design decisions and their reasons,
map file format design, what's not yet implemented, and ZZT background
for future development sessions.

and key design decisions made during this session.

Introduces a map file format: TOML with a [palette] mapping characters
to (Glyph, Element) definitions and a [grid] multi-line string. Board
now owns the player position, objects, and portals. map_file::load()
deserializes a file and converts it to a Board via From<MapFile>.

Accounts for egui's 8px CentralPanel margin in the minimum window size.
When the window is larger than the minimum, the board is centered in the
available area.

Implements Glyph (per-cell visual), Element (shared behavior palette),
and Board (60x25 grid of (Glyph, usize) cells). Player walks around
with arrow keys and is blocked by wall elements.

Sets up eframe/egui app with basic menu bar and placeholder viewport. Adds Rhai scripting dependency for future game object scripting system.
