Bundle Station Master v0.6.0: updates stop destroying games in progress

Pin moves to v0.6.0, package version to 0.6.0:0.

README and instructions.md both promised the opposite of what now happens
and had to be rewritten: an update keeps games in progress unless the rules
actually changed, and a game that genuinely cannot replay is named in the
log rather than described as a version mismatch.

Verified on phoenix.local by doing the thing the release is about. A game
(MAIL-4571) was created on the installed 0.5.6:0, then this build was
installed over it. All four saved games on the volume came back:

  Resuming 4 saved game(s)…
  Resumed HOPPER-4607  — 37 intents replayed.   (written under 0.5.2)
  Resumed TRESTLE-5109 —  5 intents replayed.   (written under 0.5.3)
  Resumed TENDER-8092  — 38 intents replayed.   (written under 0.5.5)
  Resumed MAIL-4571    —  0 intents replayed.   (written under 0.5.6)

The first three had been refused on every boot since the release that
stranded them. They were never damaged, only unreachable, and replaying
them is all it took to get them back — which is the clearest evidence that
the version comparison was answering the wrong question. All four now show
in Games in Progress with the correct Day, Stage and waiting-on player.

+**Updating the package keeps games in progress, unless the rules actually changed.** On boot the
+server replays each saved game's moves through the current engine and resumes it if they all still
+apply — the version that wrote the file is recorded and reported but decides nothing. When a move
+*is* rejected, that game is refused and the log names it: `move 3 of 8 (localOps.choose) is
+rejected by the current rules with OPTION_ALREADY_CHOSEN`. A refused game is never modified or
+deleted, so reinstalling the previous version makes it loadable again and it can be played out.

+Earlier versions of this package compared version strings instead, which destroyed every game in
+progress on every update, including updates that changed only how the board is drawn.
