Adds lib/tcl/conformance.sh: runs .tcl programs through the epoch
protocol, compares against # expected: annotations, writes
scoreboard.json and scoreboard.md. All 3 classic programs pass.

pl-hs-query, pl-hs-predicate/1,2,3, pl-hs-install in hs-bridge.sx.
No parser/compiler changes: Hyperscript already compiles
`when allowed(user, action)` to (allowed user action).
Total 590/590.

FORMAT with ~A/~S/~D/~F/~%/~&/~T/~P/~{...~}/~^; cl-fmt-loop,
cl-fmt-find-close, cl-fmt-iterate, cl-fmt-a/cl-fmt-s helpers.
Fix substr(start,length) semantics throughout: SUBSEQ end formula
corrected to (- end start), cl-fmt-loop char extraction fixed.

defmacro/macrolet/symbol-macrolet/macroexpand, gensym/gentemp, full
LOOP macro (loop.sx) with all clause types. Phase 2 dynamic variables:
cl-apply-dyn, cl-letstar-bind, cl-mark-special!/cl-special? for
defvar/defparameter specials with let-based dynamic rebinding.
27 macro+LOOP tests; 182 eval tests (8 new dynamic var tests).

cl-debugger-hook: mutable global (fn (c hook) result); cl-invoke-debugger
calls it with infinite-recursion guard (sets hook nil during call).
cl-error now routes unhandled errors through cl-invoke-debugger instead of
bare host error — allows the hook to invoke a restart and resume.
cl-break-on-signals: when set to a type name, cl-signal fires the debugger
hook before walking handlers if the condition matches.
cl-invoke-restart-interactively: calls the restart fn with no args (no
terminal protocol — equivalent to (invoke-restart name)).
4 new tests in conditions.sx covering all three; Phase 3 fully complete.

cl-debugger-hook global (nil = default), cl-invoke-debugger walks the hook,
cl-error-with-debugger routes unhandled errors through the hook, and
make-policy-debugger builds a hook from a (fn (condition restarts) name)
policy function. Tests: hook receives condition, policy selects use-zero/abort
restarts, compute-restarts visible inside hook, handler wins before hook fires,
infinite-recursion guard. Wired into test.sh program suite runner.

restart-demo.sx: safe-divide with division-by-zero condition, use-zero
and retry restarts. Demonstrates handler-bind invoking a restart to
resume computation with a corrected value.
parse-recover.sx: token parser signalling parse-error on non-integer
tokens, skip-token and use-zero restarts. Demonstrates recovery-via-
restart and handler-case abort patterns.

define-condition with 15-type ANSI hierarchy (condition/error/warning/
simple-error/simple-warning/type-error/arithmetic-error/division-by-zero/
cell-error/unbound-variable/undefined-function/program-error/storage-condition).
cl-condition-of-type? walks the hierarchy; cl-make-condition builds tagged
dicts {:cl-type "cl-condition" :class name :slots {...}}. cl-signal-obj
walks cl-handler-stack for non-unwinding dispatch. cl-handler-case and
cl-restart-case use call/cc escape continuations for unwinding. All stacks
are mutable SX globals (the built-in handler-bind/restart-case only accept
literal AST specs — not computed lists). Key fix: cl-condition-of-type?
captures cl-condition-classes at define-time via let-closure to avoid
free-variable failure through env_merge parent chain.
55 tests in lib/common-lisp/tests/conditions.sx, wired into test.sh.

Three-part fix for hs-upstream-core/asyncError test 2/2:
1. runtime.sx hs-win-call: when an async call returns a rejected promise,
store the error value in window.__hs_async_error (side-channel) and
raise the sentinel "__hs_async_error__" so the value survives the
raise boundary intact.
2. compiler.sx catch clause: inject `(let ((var (host-hs-normalize-exc var))) ...)`
around the catch body so the sentinel gets swapped for the real error
object before user code runs. Uses let (not set!) so shadowing works
correctly for guard catch variables.
3. tests/hs-run-filtered.js:
- host-promise-state wraps JS Error objects as plain {message:...} dicts
before they cross the WASM boundary (Error.toString() was producing
"Error: boom" strings instead of accessible objects)
- host-hs-normalize-exc native retrieves the side-channel value when
the sentinel arrives in a catch variable
- host-get coercion restricted to El instances — plain JS objects with
a "value" key were being stringified to "[object Object]"

Add (when (not (nil? target)) ...) guards after every hs-null-raise!
call in both the compiler and runtime so execution stops cleanly when
a DOM element is not found, instead of continuing into a JS operation
on null that takes ~34 seconds to propagate.
Compiler: emit-set dot/poss, emit-inc/dec poss case, remove-element,
remove-attr, add-styles all now wrap the action after hs-null-raise!
in a nil guard.
Runtime: hs-toggle-class!, hs-toggle-between!, hs-dispatch!,
hs-set-attr!, hs-toggle-attr!, hs-set-inner-html!, hs-put!,
hs-transition all guarded — hs-settle and hs-measure already were.

lib/js/stdlib.sx (36 forms):
- Bitwise ops (js-bitand/bitor/bitxor/lshift/rshift/urshift/bitnot) use
truncate instead of js-num-to-int (which calls integer /0 and crashes).
- Map class: dict-backed list-of-pairs with linear-scan find, mutable via
dict-set!; js-map-new/get/set!/has/delete!/clear/keys/vals/entries/for-each.
- Set class: backed by SX make-set primitive; set-member?/set-add!/set-remove!
all take (set item) argument order — fixed from (item set) which threw.
- RegExp: callable lambda wrapping js-regex-new (not a dict, so directly callable).
- Wires Map/Set/RegExp into js-global.
lib/js/test.sh: epochs 6000-6032 (25 tests) — all pass.
Result: 492/585 tests pass (was 466/560 before this phase).
