Use Scala 3.3.7 LTS via With.scala3 and fix BAST tests

respencer-ncl · claude · respencer-ncl · commit 7d04122fb9b7 · 2026-01-26T22:25:29.000-05:00
- Remove hardcoded Global/scalaVersion, use With.scala3 from sbt-ossuminc
- Fix DeepASTComparison to compare offsets instead of line/col
  (BAST preserves offsets correctly; line/col computation differs due to
  synthetic line structure in BASTParserInput)
- Fix BASTFileReadTest to not require pre-existing .bast file
- Fix BastGenCommandTest to use actual command name "bastify"
