Write comprehensive PHILOSOPHY.md covering Lux's six core principles
(explicit over implicit, composition over configuration, safety without
ceremony, practical over academic, one right way, tools are the language)
with detailed comparisons against JS/TS, Python, Rust, Go, Java/C#,
Haskell/Elm, and Gleam/Elixir. Includes tooling audit and improvement
suggestions.
Add `lux philosophy` command to the compiler, update help screen with
abbreviated philosophy, and link from README.
