Phase 3d: declaration modifiers become @annotations (Rule A)

Browse source 
edge/pure/export prefix keywords retired; modifiers are now leading @annotations
(@export, @edge, @pure, @deterministic). parse_one_decl collects a leading @anno
run and @export sets the fn export flag; dead edge-dispatch removed from
parse_system. Migrated examples/lib/combat.ludic; old prefixes now rejected.

Behavior-identical: the export flag is parse-only in the self-hosted emitter
(emits @fn_<name> for every fn, never reads the flag), so IR is byte-identical.
Reseeded, fixpoint holds, test.sh 14/14. Docs updated. Phase 3 complete.

Phases run in this order every frame: **`Start`** (once at boot), then each
frame **`Input` → `FixedUpdate` → `Update` → `LateUpdate` → `Render`**.
`edge system` marks a system that touches the outside world.
`@edge` in front of a `system` marks one that touches the outside world.
Declaration modifiers are `@annotations` written in front of the declaration —
`@export fn …` (a C-ABI-exported function), `@edge system …`, `@deterministic`,
`@pure`. They parse into one uniform channel rather than a set of prefix
keywords. (`@export` sets the export flag; the others parse but have no codegen
effect in the self-hosted compiler yet.)
