fix: Jump to correct column for class-level fixture definitions

scan_fixtures was only storing the row, causing jump/fixture.lua to
always land at column 0. For fixtures defined inside a class the def
keyword is indented, so column 0 was wrong. Now stores col from
func_node:start() and the jump uses it.
