The `cc` link now passes `-s`, discarding the symbol table + DWARF at
link time. Both link entry points funnel through link_executable_at, so
one flag covers host fixtures and `ckc run`. The emitted helloWorld binary
drops from 6,709,448 B (not stripped) to 2,180,576 B (stripped) -- 67% --
with `hello, world` and the actor lifecycle on the meta stream unchanged
(observability is the meta stream, not DWARF).

Remaining ~2.1 MB is static glibc + Rust std (fixed floor baseline);
current-state.md §6 tracks the deferred path (musl-static, panic=abort,
opt-level=z) as open, design-touchy debt.

Gates: cargo fmt --check clean; clippy 0/0; cargo test --workspace pass;
helloWorld runs stripped in the ckc container.
