Tetra Insight

0.1.8-tetra6.9 (Tetra 6.9 compatibility build)

Syncs the Tetra 6.9 backport with mainline 0.1.7–0.1.8:

• Extract improvement preview composition into a shared composer so click, hover, and comparison paths follow the same rules.
• Refresh material-dossier usage trees when resource reloads rebuild the material index, and compare full material profile snapshots so updated data refreshes an open dossier.
• Split generated attribute sorters by operation: additive rows show the added amount, multiplier rows show the × factor, fixing pure-multiply attributes that rendered as unreadable final values.
• Group the sorter popover into module-provided and material-provided sections with the clear action pinned first; bound material-group sorters to stats that actually vary across the schematic's candidate materials.
• Add a search field, material-axis sort buttons and group folding to the holosphere material browser.
• Space out the compact improvement overview rows for clearer five-row pages.
