2f7f8189ea GUEST: step 0 — baseline snapshot 
Created lib/guest/baseline/ with normalised scoreboards for all 11 guests:
lua 185/185, forth 64/64, ruby 76/76, apl 73/73, prolog 590/590,
common-lisp 309/309, smalltalk 625/629, tcl 3/4, haskell 0/18 programs,
js 94/148 (test262-slice), erlang 0/0 (suite all-zero).

Re-ran every conformance.sh and test.sh; refreshed each guest's own
scoreboard.{json,md} so per-guest scoreboard matches lib/guest/baseline/<lang>.json.

e80e655b51 sx: step 2 — restore frame locals on browser VmSuspension resume 
In `resume_vm`'s `restore_reuse`, the saved sp captured by
`call_closure_reuse` was ignored when restoring the caller frame after the
async callback finished. The suspended callee's locals/temps stayed on the
value stack above saved_sp, so subsequent LOCAL_GET/SET in the caller
frame (e.g. letrec sibling bindings waiting on the suspending call) read
stale callee data instead of their own slots. Sibling bindings appeared
nil after a perform/resume cycle on the JIT path used by the WASM
browser kernel.

Fix: after popping the callback result and restoring saved_frames, reset
`vm.sp <- saved_sp` (when sp is above), then push the callback result.
Mirrors the OP_RETURN+sp-reset discipline that sync `call_closure_reuse`
already follows.

New tests in `spec/tests/test-letrec-resume.sx` cover single binding,
sibling bindings, mutual recursion siblings, and nested letrec —
all four pass. Full OCaml run_tests: 4529/5868 (was 4525/5864), zero
regressions.

882a4b76cb sx: step 1 — fix JIT call_closure_reuse for closure returns 
In `call_closure_reuse`, the success path used a bare `pop vm` that relied on
OP_RETURN having left the stack at exactly `saved_sp + 1`. When the callee
returns a closure (or hits the bytecode-exhausted fallback path), `vm.sp` can
end up inconsistent with the parent frame's expected layout, corrupting
intermediate values such as parser combinator state in `parse-bind`/`many`/
`seq`.

Fix: read the result at the expected slot, then explicitly reset
`vm.sp <- saved_sp` before returning so the parent frame sees a clean stack
regardless of what the callee left behind.

OCaml run_tests baseline: 4525/5864 unchanged. WASM kernel tests: 24/29
unchanged. No regressions.

Brings in 306 commits from architecture:

- OCaml: HTML renderer, Python bridge, epoch protocol, sx_scope.ml
- Language libs: common-lisp, erlang, forth, apl, prolog, tcl, smalltalk, ruby

Conflict resolution: hs-f version kept for all hyperscript .sx files (superseding
architecture's smaller additions). Architecture's platform.py kept with hs-f's
domListen _driveAsync fix applied.

f0f339709e tcl: replace eager coroutine pre-execution with true suspension via fibers
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 45s
Details 
Rewrote the coroutine implementation to use lib/fiber.sx (make-fiber,
fiber-resume, fiber-done?) instead of eagerly running the proc body and
collecting all yields into a list. Each coroutine is now a live fiber —
calls to the coro command invoke fiber-resume, yield suspends via call/cc.

- make-tcl-interp: remove :coroutines/:in-coro/:coro-yields, add :coro-yield-fn nil
- tcl-cmd-yield: calls :coro-yield-fn (fiber's yield fn) to truly suspend
- tcl-cmd-yieldto: same pattern, yields "" to resumer
- make-coro-cmd: takes fiber (not coro-name), calls fiber-resume on each invoke
- tcl-cmd-coroutine: creates a fiber whose body runs the proc with :coro-yield-fn set
- tcl-call-proc result merge: drop :coro-yields/:coroutines propagation
- test.sh: load lib/fiber.sx before lib/tcl/runtime.sx in epoch 4

All 337/337 tests pass including all 20 coro tests.
