re: generalize the two capture tools beyond weapons

idxd_tokens took the sub-record type list as an argument already but still
hard-filtered entries to those declaring a `Weapon_*` id, so it could not be
pointed at another schema. Filter on the requested type names instead -- it now
splits `EnumUnit` (Generic/Maneuver/Shield/Explosion/Frame/Turret/...) too.

gmem: honour $GMEM_FILE. `cp --sparse=always /dev/shm/xenia_memory_* snap.bin`
takes ~2 s and reads identically, which matters because a running Canary pegs
every core under lavapipe and makes repeated live reads stall unpredictably.

Groundwork for the craft (UNIT) stats. Not a finding yet: in menus only the
player craft's *name* is resident -- the flight-model object is not instantiated
until a mission loads, so that needs an in-mission snapshot.
