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.

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>.
