The metadata-grid hover infrastructure shipped but no table entry fed it, so every cell tooltip the previous version had was silently gone: the heap-offset/value hints on string and blob columns, the entity description on token columns, and the per-bit breakdown on flag columns. Reinstate all of them. FlagsTooltip renders the rich per-bit view (a checkbox per flag plus the selected member of each mutually exclusive sub-range) instead of a flat string; GenerateTooltip on the table base describes what a token column points at; the remaining columns expose their heap-offset and value hints. MetadataCellTooltip now hands a FlagsTooltip back as a built control and stringifies everything else. Assisted-by: Claude:claude-opus-4-8:Claude Codepull/3755/head
