Per Task 3 of the 2026-09-14 ASCII art upgrade plan.
- New module: src/main/AsciiArt.templates.js exporting ASCII_TEMPLATES
(19 entries) and getTemplate(name) accessor (returns '' for unknown).
- New test: tests/main/ascii-art.templates.test.js with 19 per-template
snapshots + unknown-name + keys-match assertions (21 tests total).
- 17 templates verbatim from src/ascii-generator.html:596-626
(arrow-right, arrow-down, decision, process, flowchart, sequence,
network, hierarchy, header, note, warning, info, divider, separator,
banner, checklist + the brief's own TEMPLATE_NAMES order).
- 2 templates verbatim from src/renderer.js:6542-6697
(progress-bar, table-simple).
- 1 newly authored: arrow-up (completes the arrow triplet; does not
exist in either source).
