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.

# reseed.sh — regenerate the checked-in IR seed after a deliberate change to the
# self-host compiler. Uses the CURRENT seed (C-free) to produce the new one, so
# the C compiler is not reintroduced; falls back to the C ludicc if no seed
# builds. Always verify with ./selfhost/bootstrap-cfree.sh afterwards.
