fix(parse): position-independent inline metadata parsing (#164)

Problem: `parse.body()` scanned tokens right-to-left and broke on the
first non-metadata token, so metadata only worked at the trailing end
of a line. `due:tomorrow Fix the bug` silently failed to parse the
due date.

Solution: Replace the right-to-left `while` loop with a single
left-to-right pass that extracts metadata tokens from any position.
Duplicate metadata tokens are dropped with a `log.warn`. Update docs
and tests accordingly.
