feat(ascii-art): 19 named ASCII art templates with snapshot tests

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).

+ * `arrow-up` is the only template authored for this module — it completes the
