chore(release): 0.27.0-fork.26 — stealth navigator.platform=MacIntel (anti-detection fix)

fix(stealth): navigator.platform = MacIntel/Win32/Linux x86_64 (was UA-CH value)
platform_string() feeds the CDP Emulation.setUserAgentOverride 'platform' field, which sets the LEGACY navigator.platform. It was returning the UA-CH form ("macOS"/"Linux") — but real Chrome reports navigator.platform = "MacIntel" on macOS and "Linux x86_64" on Linux. "macOS" contradicts the UA's "Intel Mac OS X" and is a trivial bot-detection tell (platform vs UA mismatch). UA-CH (navigator.userAgentData.platform via platform_hint) stays "macOS"/"Windows"/ "Linux" — that form is correct there. Verified locally on bot.sannysoft.com (all rows green incl. navigator.platform= MacIntel) + eval probes: webdriver false, no Headless in UA, real WebGL (Apple M3 Metal, not SwiftShader), plugins/permissions consistent.
