emrg: task main table one-line layout — task-meta flex-basis:100% → flex:0 1 auto (rant 2026-08-20T10:34:40)

[argszero]

Fix the GUI task management main-table layout regression reported by the host (rant 2026-08-20T10:34:40): each task card rendered as 3 lines instead of one compact row.

Root cause

• .task-meta (components.css) used flex-basis: 100%, forcing the "last run" metadata onto its own full-width line.
• .task-row is flex-wrap: wrap (added in emrg: persist task execution records to JSONL + fix task-row flex-wrap #876 for the expandable sub-table), so the actions (flex-shrink: 0) that no longer fit also wrapped to a third line.

Fix

• .task-meta: flex-basis: 100% → flex: 0 1 auto — content-sized, shares the row with the actions; wraps internally (flex-wrap: wrap retained) on narrow windows.
• .task-row keeps flex-wrap: wrap; .task-run-detail keeps flex-basis: 100% (expandable sub-table still renders below the card, not to the right).

Verification

• GUI: npm test 253/260 pass (7 integration fails are the known daemon-spawn tests that fail locally by design, green in CI).
• Added a renderer-smoke CSS assertion: .task-meta must not contain flex-basis: 100% and must be flex: 0 1 auto.
• Python suite unaffected: pytest 986 passed + 1 skipped, import + CLI green.

✅ LGTM — cycle (self-review). CI test + test-windows green (32325523343). Change is minimal: .task-meta flex-basis:100% → flex:0 1 auto; .task-row flex-wrap and .task-run-detail flex-basis:100% intentionally preserved; renderer-smoke CSS assertion added; pytest 986 passed + 1 skipped.

✅ LGTM — cycle (independent re-review). Head unchanged since 1st LGTM; CI test + test-windows still green (32325523343). Diff verified: .task-meta flex-basis:100% → flex:0 1 auto keeps the main table on one line while .task-run-detail retains flex-basis:100% for the expandable sub-table; smoke assertion added.

✅ LGTM — cycle (3rd consecutive, cycles 1130/1131/1132). Head unchanged, CI green. Merging.
