docs(README): drop LLM-style typographic characters

Replaced em-dashes (—) with commas, colons, or periods depending on
context. Kept all emoji (✅/❌/⚠️) in the comparison table since
those are scannable scoring cues, not stylistic.

Net cleanup: 6 em-dashes removed from tagline, hero alt-text,
"Why it's powerful" paragraph, and the comparison intro.

 ## How it compares
 
-The closest peer in the source-level patching space is **Camoufox** (Firefox, open source) — same approach as ours, but in a roughly year-long maintenance gap with its base Firefox several majors behind. **CloakBrowser** ships a similar pitch for Chromium, but its binary is **closed source** (the source-level patches are not published — you only get the compiled output), and it still hits the Chromium reCAPTCHA ceiling. The commercial anti-detect browsers (**Multilogin**, **GoLogin**, AdsPower, Dolphin, Kameleo) are paid SaaS that overlay JS-layer spoofing on a patched Chromium — managed profiles are nice but raw detection bypass sits below both Camoufox and us.
