grammar(P0): add peek expression, continue statement, and field type annotations acceptance; add sample apps and interpreter path\n\n- tokenizer: add keywords (peek, continue), tokens (=> as FatArrow, :: as DoubleColon), keep >> as Arrow\n- parser: implement peek as expression (literal patterns only, else required), add continue; accept field 'name: Type' (discard type P0)\n- interpreter: evaluate PeekExpr; add Continue control flow handling\n- apps: add peek-demo, loop-continue-demo, adjust field-decl demo; use ConsoleBox instead of env.console for interpreter backend\n- docs: CURRENT_TASK updated earlier for Phase 12.7 P0\n\nNOTE: peek arms currently single-expression (no block expr yet); VM/MIR path does not lower PeekExpr yet; use --backend interpreter for demos
