re: the GP_MAIN_GAME unnamed block -- 333 of 337 already owned, 4 genuinely new

All six language copies carry the identical 337 unnamed IDXD hashes.  Partitioned
by record-name shape (53 shapes), 333 map onto families the corpus already
documents: 131 weapon datasheets, 114 unit datasheets, 64 unit Faces tables, 10
unit message sets, 8 chatter rule tables, 5 enumerations/formations/placement.

114 is exactly the corpus's unit count (43 Craft + 71 Vessel) -- these are the
tables the corpus has always worked with, reached by SHAPE because they have no
names.  Naming them adds nothing.

The Enumerate object in each GP_MAIN_GAME_* is EMPTY, zero fields, which is why
route 2 named 1283 entries in DefTables and 0 here.

The 4 unclassified objects are new -> docs/re/structures/player-tuning-tables.md:
the analog stick response curves (8 axes, 11 samples + a named Count = 11, tested
8/8; yaw/roll/throttle are the identity ramp, the shaping is all on pitch and the
camera axes; adv_yaw is non-monotone and unexplained), the player craft's flight
envelope (Booster, 50 fields -- the player side of the AA_/AV_ pair documented
for NPCs -- plus TacticalManeuver, SpecialAttack + three gauge bands,
SpecialWeapon, Misc), the Stage 16 boss (identified by Shell_S16Boss_* ids;
Guardian HP 65000, Core 42000), and one unidentified Generic naming eff_n0071.

New regenerator main_game_unnamed.py, 112-line artefact, byte-identical across
two runs; the other twelve artefacts verify unchanged.
