Draft: [SUS-2996] Ignore every word in functional comments ($ sign) if not in *POIN section

Simon Huangrequested to merge
SUS-2996 into dev

https://its.cern.ch/jira/browse/SUS-2996 \

Summary of changes:

  1. Lexer state variable (_inFunctionalComment): Tracks whether we're inside a functional comment on the current line
  2. Lexer logic: When $ is seen, set _inFunctionalComment = true. All subsequent tokens on that line are returned as WORD (bypassing keyword matching)
  3. Line boundaries: Reset _inFunctionalComment at the start of each new line
  4. Grammar simplification: Back to a single FunctionalCommentString rule that accepts WORD | DOLLAR | Number — which is now safe because keywords like SX, SY, SZ inside comments are returned as WORD

This means:

  • In *POIN sections, in functional comments, ignore everything after DCUM and Spad ID
  • In *PLR3D and other measure sections, everything after $ is treated as comment (no keyword matching) (FunctionalCommentStringMeasures)
