Move all package-level vars into gameData; finish lint adoption

gochecknoglobals: all 37 package-level tables consolidated into the
gameData struct (game/tables.go), built by newGameData() and carried
on RogueGame as g.data (set in NewGame and Restore). ObjectKind
Glyph()/objectKindForGlyph are now switches; the table-reading subtype
Stringer methods are gone; isMagic is a RogueGame method.

goconst: repeated words named (potionName/scrollName/ringName/goldName
in object.go, wandName/staffName in sticks.go, ripWall in tables.go).

exhaustive, testpackage: disabled in .golangci.yml with sneak's
approval (2026-07-07).

Also reverts misspell's silent corruption of the "ther" scroll-name
syllable (it had become "there", changing generated scroll names vs C).

Remaining red: cyclop/gocognit/nestif until refactor step 7; mnd
awaits a ruling. TODO.md rotated; MEMORY.md lint notes updated.
