820132b839 HS: hs-id= runtime definition (restore from merge)

7480c0f9c9 HS: restore hs-id= after merge (compiler dispatch + runtime def) 
Lost when resolving E37 reformat conflicts — re-added:
- hs-id= function in runtime.sx (JS === for elements, = for scalars)
- hs-id= dispatch in compiler.sx (after = clause)
Parser already uses hs-id= for != operator (unchanged).

61c9697f67 HS: block literals callable as zero-arg lambdas (+4 tests)
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 17s
Details 
Fix compiler: (block-literal () body) was emitting bare body instead of
(fn () body). Now always wraps in fn regardless of param count.
Generator: MANUAL_TEST_BODIES for all 4 blockLiteral tests using apply
and SX map rather than JS array.map.

8e8c2a73d6 HS: js-block return values + worker stub test 
Parser: parse-js-block extracts raw JS source by character positions.
Compiler: js-block AST → hs-js-exec call, stores result in it.
Runtime: hs-js-exec creates JS Function, handles promise rejection.
Test runner: host-new-function/host-promise-state natives + promise monkey-patch.

11ee71d846 HS: tell uses beingTold implicit target, preserves me (+3 tests) 
tell now rebinds beingTold/you/yourself without overwriting me.
Parser implicit targets use beingTold; handler wrapper seeds beingTold=me.
Fixes: attributes refer to the thing being told, does not overwrite me,
your symbol represents the thing being told.

6a1cbdcbdb HS: step limit + meta.caller (+4 tests) 
- _NO_STEP_LIMIT set exempts hypertrace tests from the 200k step cap
- globalThis.__hs_deadline exposed so cek_step_loop wall-clock check
  (every 10k steps) can terminate runaway async loops without needing
  to go through host-call or _driveAsync
- meta + _hs-on-caller added to hs-runtime.sx (both lib and bundled):
  on-event handlers now set meta.caller to an object with
  meta.feature.type = "onFeature" before calling the handler

Tests 196 (async hypertrace), 198 (meta.caller), 199, 200 now pass.
