DRAKHYSYS STORY MAKER — V4.8.8.107
DIALOGUE CONTINUITY FIX

The dialogue editor now makes spoken-line flow explicit instead of displaying
DLG states as if their row order alone were a conversation.

Changes:
- LINES / STATES now has a "Continues to" column showing automatic links,
  player-choice destinations, and lines that currently stop.
- ADD NEXT LINE automatically creates a silent DLG transition from the selected
  line to the new line when the selected line has no existing answer/branch.
  Existing answers and branches are never replaced.
- AUTO-LINK UNCONNECTED LINES repairs an existing simple sequence by creating
  silent state N -> state N+1 transitions only where a non-final line currently
  has no outgoing transition.
- During AUTO-LINK, a destination whose entry condition is only the old generic
  True() default is made branch-only (blank trigger). Custom conditions are kept.
- Selecting a line with no transitions now explains that the line stops there
  and tells the user how to continue it.
- The final line is intentionally left without a transition unless the user adds
  an answer/branch; that represents the end of that chain.

This does not rewrite imported dialogues automatically. Use AUTO-LINK only when
consecutive rows are intended to be one spoken sequence. Existing player choices,
external DLG links, scripts, actions, flags and custom entry conditions are kept.

Runtime note: source syntax was validated in this environment. The included Qt
regression suite could not be executed here because PySide6 is not installed in
the current container runtime.
