Chris Pak 84779f8a28 Removes dead code, tightens idioms, adds clarifying comments ...

Dead code removed:
  cursor.rb:     parse_for_markup + attr_reader :for_var/collection/reversed
                 (zero callers in lib/; method also incomplete -- no limit/offset)
  for.rb:        Syntax regex, REVERSED_BYTES constant (both unreferenced by
                 lax_parse and strict_parse)
  block_body.rb: BLANK_STRING_REGEX (exact duplicate of WhitespaceOrNothing)

Idioms:
  expression.rb:    parse_number returns nil on failure, not false
                    (Ruby convention for 'no result'; callers use if (num = parse_number))
  block_body.rb:    freeze (idempotent by spec); whitespace_handler marked private;
                    render_node gets rationale comment; redundant comments collapsed
  variable_lookup.rb: COMMAND_METHODS -> %w[]; initialize loop uses each_with_index;
                    removes redundant &. on second clause of &&
  for.rb:           strict2_parse -> alias_method; nil-guard if/else -> ternary;
                    render_else -> ternary; include? checks unconsumed rest only
  condition.rb:     loop/break chain -> while condition.child_relation
  utils.rb:         tightens slice_collection_using_each loop

Comments:
  variable.rb:         backward pipe-walk algorithm; SPACE-only whitespace asymmetry
  cursor.rb:           COMPARISON_OPS identity-map exists for frozen string interning
  if.rb:               include? pre-check is both correctness guard and perf gate
  for.rb:              cursor->regex fallback for limit:/offset: attributes
  strainer_template.rb: __LINE__+1 limitation in module_eval loop
