fix(textobj): escape Lua pattern hyphen, fix test expectations

Problem: inner_task_range used unescaped '-' in Lua patterns, which
acts as a lazy quantifier instead of matching a literal hyphen. The
metadata-stripping logic also tokenized the full line including the
prefix, so the rebuilt string could never be found after the prefix.
All test column expectations were off by one.

Solution: escape hyphens with %-, rewrite metadata stripping to
tokenize only the description portion after the prefix, and correct
all test assertions to match actual rendered column positions.
