pirate: re-mine with path-component exclusions

After fixing the substring-exclusion bug ('out/' over-matching 'layout/',
'build/' matching 'rebuild/', etc.), totals jump significantly:

  commits  17,734 -> 27,610   (+56%)
  +lines    8.67M -> 20.33M   (+135%)
  -lines    5.12M -> 16.33M   (+218%)
  repos       402 ->    461   (+15%)
  prs ✓   716/884 -> 720/893
  stars     133K  -> 134K

The dedup-by-SHA logic is unchanged; the increase is entirely from
no longer dropping legit src/layout/, src/checkout/, src/routes/,
src/environment/, etc. that the old substring matcher false-positively
excluded.
