* Move navigator fingerprint props onto Navigator.prototype
Spoofed navigator properties (userAgent, appVersion, platform, language,
languages, plugins, mimeTypes, hardwareConcurrency, deviceMemory, webdriver,
share, canShare) lived as own-instance accessors/data props on the navigator
literal, which pixelscan's Navigator group flags via hasOwnProperty /
getOwnPropertyDescriptor. Real Chrome keeps them on Navigator.prototype.
Generalize the existing webdriver prototype IIFE to define every spoofed
accessor on a thin prototype one hop above Navigator.prototype, so
navigator.hasOwnProperty('platform') === false while navigator instanceof
Navigator stays true. Getters read the __obscura_* globals lazily (snapshot
vs per-page timing) and are _markNative'd so toString reports [native code].
plugins/mimeTypes are cached singletons.
hardwareConcurrency/deviceMemory now back onto __obscura_hw/__obscura_mem
globals written by __obscura_init, avoiding own data props. Those two globals
are pre-declared in _preHideInternals so the snapshot-time hide list captures
them and they stay invisible to reflection APIs.
* Tighten comments on navigator prototype fingerprint setup
Drop the long narrative blocks in bootstrap.js; keep short notes on why
props sit on the prototype hop, plugin caching, and hw/mem globals.
