fix(backlinks): honor positional check-backlinks directory argument

The help text (gbrain check-backlinks <check|fix> [dir]) promised a
positional directory argument, but runBacklinks only parsed --dir and
defaulted to cwd, so the walker ran from the wrong root and could hit
EPERM on unreadable sibling dirs.

Extract parseBacklinksArgs: positional [dir] is now honored, --dir still
overrides it, --dry-run preserved, and a --dir flag missing its value
falls back to the positional dir instead of picking up undefined.

Takeover of #852 (rebased onto master past the findBacklinkGaps dedupe
test block). Fixes #485.
