Baseline: Ludic compiler + toolchain, Phase 1 syntax fixes complete

Browse source 
Self-hosted compiler (selfhost/*.ludic), runtime, examples, editor tooling,
and docs. Phase 1 of the syntax-redesign cohesion pass has landed:
edge-system fix, signature-query, when-alias, and the documentation truth-pass.
Suite green (14/14), C-free bootstrap fixpoint holds.

# bootstrap.sh — the self-hosting proof.

# stage0: the C compiler (build/ludicc) compiles the self-host source -> gen1
# stage1: gen1 compiles the self-host source -> gen2
# stage2: gen2 compiles the self-host source -> gen3
# assert: gen2.ll == gen3.ll (the compiler reproduces itself exactly)
#
# gen1 is built by a *different* compiler (the C one), so its IR legitimately
# differs; gen2 == gen3 is the fixpoint that proves independence.
