re: the stage numbering is consistent everywhere; the manifest still declares the cut S17

Browse Source 
Correction first: the previous commit claimed the corpus 'did not know
the stage NUMBERS'.  It did -- structures/mission-script-ssb.md has
recorded S01-S16, S18-S29, S17 absent by a three-way convergence (hash
lookup, the table sweep, the loader's != 16 guard) since before that
pass.  What was actually new there is the player craft per stage and
ResourceID's ordinal tags; the numbering is a fourth independent route,
not a discovery.

The question this item asked: do the ISL StageNN.ssb files and the
UnitGroup_SNN.tbl tables use the same numbering, or is something
silently mis-labelled?  They are identical.  Stage\StageNN.ssb,
stage\UnitGroup_SNN.tbl and stage\Route_SNN.tbl all resolve for the
same 28 N with an EMPTY symmetric difference; AIParams is the same minus
18-23.  Nothing in the corpus is mis-keyed.  Formation_SNN and
Message_SNN resolve 0/40 -- those are field names, not files, and the
four families above are the controls that make that negative real.

New: Stage\script.tbl's SCRIPTS record lists 29 MISSION*.ssb fields --
MISSION1..MISSION29, including MISSION17 = Stage17.ssb -- and only 28 of
29 name a file that ships.  Control: MISSIONn -> Stage<n>.ssb with the
same n, 0/29 mismatched.  So S17 is a cut mission the shipping manifest
still names, which is why the loader carries an explicit != 16 guard
rather than just running 0..27.

Artefact +14 lines / 0 deletions; the other four regenerate
byte-identical.
