Thinner close button stroke and deduplicate shared resources

[Copilot]

Reduce close button SVG stroke-width from 1.5 to 1.2 for a lighter visual weight, and extract duplicated resources into shared constants in src/const.ts.

• src/const.ts — new shared closeSvg and systemFont constants
• src/tooltip.ts — use shared constants instead of inline duplicates
• src/panel.ts — use shared constants instead of inline duplicates

@copilot Why you are not reusing resources here?

Can you do a full scan of the codebase to find out wasted duplicates?

Extracted the duplicated close button SVG and system font-family stack into shared constants (closeSvg and systemFont) in src/const.ts. Both tooltip.ts and panel.ts now import from there instead of inlining. Addressed in f59d045.
