Completes ticket 0001 started in 27f468c. All three impls now carry
bit-identical xoshiro256**; portal state round-trips across process
boundaries in every producer x consumer cell (Python <-> C <-> asm).
asm impl:
- 4 new builtins: random-seed!, random-int, random-state, random-state!
- g_rng_state in BSS (4 x u64); rng_splitmix64_step, rng_seed, rng_next
- Binary portal header bumped LUMBDAB1/48 -> LUMBDAB2/80; carries
32 bytes of rng state at offsets 40..64, reserved moved to 72
- No float support in asm, so (random) intentionally omitted there
- _start seeds with 0 so the stream is deterministic from startup
Python + C (supplements 27f468c):
- rng_seed(0) auto-invoked at module load / register_portal_builtins
so (random) without explicit (random-seed!) returns a real value
instead of the all-zero xoshiro fixed point
Tests:
- tests/functional.lsp: 7 new shared assertions (Python + C)
- asm/test.sh: 5 new asm-local assertions (142 -> 147)
- tests/portal-rng-save.lsp / portal-rng-load.lsp: portable S-expression
portal that captures both state AND next-5 baseline so loader self-
verifies without a separate harness
- tests/portal-cross-test.sh: 9 new producer x consumer RNG cells; all
18 cells pass end-to-end
Verified: seed=42, (random-int 1000000) draws 1..10 =
558742 543102 559009 124193 317476 750584 200754 814407 344958 929085
identical in Python, C, and asm.
unmoad scan: zero new findings in added code.
