Replace egui text rendering with a BitmapFont system:
- Glyph.tile: u32 replaces ch: char; top-left pixel of PNG is background sentinel
- BitmapFont loads/preprocesses PNG to opaque-white + transparent, tinted at render time
- Default font: assets/vga-font-8x16.png (CP437, 8×16 tiles); placeholder generated if missing
- Boards can specify a per-board font via [font] in their .toml file
- Editor Board tab: "Font…" button opens font dialog (rfd file picker, tile dims, tilesheet preview)
- Glyph picker: tile grid from active font replaces hardcoded ASCII char grid
- map_file: TileIndex untagged enum accepts char or integer in palette entries

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.

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.

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.

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.
