Phase 2: enforce statement separators (Rule B)

Browse source 
The parser now requires a newline or ';' between statements (block() in
selfhost/parse.ludic); two statements may no longer sit adjacent with only
spaces. Also fixed if-without-else swallowing its trailing separator.

Migration: tools/ludic-tools/migrate_separators.c inserts ';' at statement
boundaries corpus-wide (examples, runtime, 25 self-host fragments, ~1100
boundaries). Verified semantically identical — the migrated compiler compiles
itself to IR byte-identical to the pre-migration seed, and every golden game
renders identically. Reseeded to the strict compiler; C-free fixpoint holds;
test.sh 14/14.

Docs: Rule B documented in LANGUAGE.md; BOOTSTRAP.md R1 + stale fences updated;
check-docs green across all docs. Fixed a multi-line string literal in
emit_expr.ludic (byte-identical \n escape) that the C toolchain lexer mis-lexes.
