ci(verify): markdown-table band report (readable PR comments)

[Seungpyo1007]

Replaces the code-block band histogram with a markdown table (mirrors the TechEngineBot validation-stats style) for readability.

• app.verify score --format md → GitHub-flavored table: Category | Total | 🟢 Green | 🟡 Yellow | 🔴 Red | Green % + bold All row + hard-violations table.
• verify-report.yml uses --format md and posts the table directly (no text fence).
• Default output stays text (local CLI unchanged); md is opt-in for CI comments.

Pairs with a TechEngine change that switches the /verify and weekly-refresh comments to the same table.
