[BUG]: fix: improve tag spacing on mobile devices

[achuanya]

Description

Fix mobile spacing issue between hash symbol (#) and tag name in Tag component. The current implementation uses excessive negative margins (-me-3.5 and -me-5) on the IconHash component, causing the hash symbol to appear too close to the tag name on mobile devices, affecting readability.

This PR implements responsive negative margins that apply smaller values on mobile devices while maintaining the original spacing on desktop screens.

Specific code modifications:

// File: src/components/Tag.astro
    <IconHash
      class:list={[
        "inline-block opacity-80",
        { "-me-3.5 size-4": size === "sm" },
        { "-me-5 size-6": size === "lg" },
      ]}
    />
