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.

@ -126,7 +126,7 @@ All verified. A compiler needs each of these, and each one works today.
| `shr` is **logical**, not arithmetic | ✅ | `shr(-16, 1)` → `2147483640` |
| Character literals | ✅ | `'x'`, `'\n'`, `'\0'` lex to ints |
| Exit codes | ✅ | `os_exit(3)` → shell sees `3` |
| Separate compilation, C ABI | ✅ | `module` + `export fn`, `extern fn … = "sym"` |
| Separate compilation, C ABI | ✅ | `module` + `@export fn`, `extern fn … = "sym"` |
**The consequence:** a compiler is *already expressible* in Ludic today. You
could write a lexer, a parser building nodes as hand-offset `peek32`/`poke32`
