fix(mobile): count grep/glob badge from sheet rows

[iscekic]

Summary

• User: the grep and glob tool cards now show a badge count that matches the files shown when you tap the card. A card with only a Found N summary and no files no longer shows a misleading 1 matches badge.
• Product: the badge count on grep/glob cards now reflects the actual visible result rows, removing a misleading off-by-one badge.
• Maintainer: getToolDisplay now derives the badge from buildResultRowsModel(output, kind).rows.length instead of a raw non-empty-line count, so the lifted Found N caption is not counted. The badge is omitted when the model has zero rows.

Verification

• Automated only: pnpm --filter kilo-app exec vitest run src/components/agents/tool-card-display.test.ts (36 tests pass), pnpm --filter kilo-app typecheck, pnpm --filter kilo-app lint.
• No manual device test: this is a pure string projection, unit-tested against the same model the sheet uses.

Reviewer Notes

• E2E: bot-e2e — skipped; pure string projection unit-tested against the same model the sheet uses. No runtime behavior to verify on a device.
• Human steps: none.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Reviewed the grep/glob badge fix at HEAD 1c82d0f: getToolDisplay now derives the badge from buildResultRowsModel(output, kind).rows.length — the same pure model the detail sheet renders — so the badge matches visible rows and is omitted when only a lifted Found N caption exists. The change is a pure string projection with no state, side effects, or memory-leak surface; the four new unit tests pin both the counting and badge-omission behavior for grep and glob.
