ovecc 0.2.1

Fixed

• review no longer blames pre-existing clone families on the change. A family
  is charged only when the change touched one of the tokens it is made of, so
  reflowing the comments around a clone does not report it as new duplication.
• review scopes an uncommitted change to the lines it touched, by diffing the
  working tree against the base commit. Two snapshots sitting on the same commit
  — the index, edit, index loop an agent runs — used to fall back to charging
  every finding and every clone family in an edited file to the change.
• Diffs normalize CRLF, so a working copy checked out under core.autocrlf no
  longer reads as if every line of every file had changed.
• dupes folds overlapping instances of one family: a block of near-identical
  lines gives consecutive sliding windows the same fingerprint, and one region
  was reported as several copies of itself. Duplicated-line counts drop 17 to
  30 percent on the six repositories benchmarked.
• Building from source on Windows works around the multiple-definition bug in
  GCC 16.1.0's libstdc++.

Changed

• The commit index stores whether a commit's subject describes a bug fix
  (schema 7). Existing databases gain the columns on the next index.
