Clean up deprecated ANSI processing code (Phase 4)

Browse source 
Removed the ansiCarryovers Map from server.ts since terminal emulation
now handles all ANSI sequence buffering internally. Marked ansi.ts and
ansi-carryover.ts as deprecated with JSDoc comments, but kept them for
backward compatibility and potential rollback.
