guangyang1206 f096548a16 fix(web): extract single tryGetHostname helper (DRY, unified fallback)
Fixes #1368

Previously,  was duplicated in 4 places with 3 subtly different fallback behaviors:
1. inline-citation.tsx: returned  on error
2. markdown-text.tsx: returned  on error
3. assistant-message.tsx: returned  on error
4. citation.tsx: returned  on error

Created canonical  in  that:
- Returns
- Strips  prefix from hostname
- Returns  on invalid URL (safest contract)

Updated all 4 call sites:
- inline-citation.tsx:  (preserves original fallback)
- markdown-text.tsx:  (preserves original fallback)
- assistant-message.tsx:  (drop-in, both return )
- citation.tsx:  (drop-in, both return )

/**
* Extract a normalized hostname from a URL. Strips a leading `www.`.
* Returns `undefined` if the input is not a parseable URL.
*
* This is the canonical replacement for the four previously-duplicated
* `extractDomain` helpers that had subtly different error fallbacks.
