New top-level Philosophy section in sx-docs. Moved SX Manifesto and Strange
Loops from Essays, added three new essays: SX and Wittgenstein (language games,
limits of language, fly-bottles), SX and Dennett (real patterns, multiple drafts,
intentional stance), and S-Existentialism (existence precedes essence, bad faith,
the absurd). Updated all cross-references and navigation.
