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.

parse-int "2.0" returns nil in SX (strict integer parse); fixed by adding
tcl-num-float? (char scan for ./e/E) and tcl-parse-num (routes to
parse-float when float-shaped). Applied in tcl-apply-binop (all arith +
comparisons), tcl-apply-func (parse-float for all math args), unary minus,
and tcl-expr-parse-power (**). Real sqrt/floor/ceil/round/pow/sin/cos/tan/
exp/log now used instead of integer stubs. Integer division still truncates
when both operands are integer-shaped. 329/329 tests green.
Parser: limit `from SOURCE` to parse-collection/cmp/arith/poss/atom
(stops before parse-logical so `or` is not consumed as binary op),
then collect `or EVENT from SOURCE` pairs via recursive collect-ors!.
Adds :or-sources key to the on-feature parts list.
Compiler: scan-on gains or-sources param (11th); new :or-sources cond
clause extracts the list; terminal `true` branch wraps on-call in
(do on-call (hs-on target event handler) ...) for each extra source.
Test: "can handle an or after a from clause" moved from skip-list to
MANUAL_TEST_BODIES and now passes (1478/1496).

When `from #doesntExist` resolves to nil, hs-on silently skips
listener registration instead of crashing on dom-listen nil.
Removes "can ignore when target doesn't exist" from skip-list.
Also adds host-make-js-thrower native utility (plain JS throwing
function, no K.callFn re-entry) — investigated for the js-exceptions
catch test but that test stays skipped: native JS throws from host
calls escape OCaml WASM try-with guards.

Parser: bracket-open in obj-collect key cond → (computed-key expr).
Compiler: detect computed-key list at object-literal pair key and compile
the inner expression instead of emitting a literal string.
Generator: special case for 'expressions work in object literal field names'
using eval-hs-locals with host-callback so hs-win-call can find the fn.

Parser parses optional deriving clause; only appended to AST when non-empty.
hk-bind-decls! data arm generates dictShow_Con / dictEq_Con per constructor.
hk-binop == and /= now deep-force both sides (SX dict equality is by
reference — two thunks wrapping the same value compared as not-equal without
this). Three token-type fixes in the deriving parser (lparen/rparen/comma,
not "special").

Implements namespace eval, current, which, exists, delete, export,
import, forget, path, and ensemble create (auto-map + -map). Procs
defined inside namespace eval are stored as fully-qualified names
(::ns::proc), resolved relative to the calling namespace at lookup
time. Proc bodies execute in their defining namespace so sibling
calls work without qualification.

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.

Phase 3 headline feature: everything falls out of SX's first-class env chain.
- make-tcl-interp extended with :frame-stack and :procs fields
- proc: user-defined commands with param binding, rest args, isolated scope
- uplevel: run script in ancestor frame with correct frame propagation
- upvar: alias local name to remote frame variable (get/set follow alias)
- global/variable: sugar for upvar #0
- info: level, vars, locals, globals, commands, procs, args, body
- tcl-call-proc propagates updated frames back to caller after proc returns
- test.sh timeout bumped to 90s for larger runtime

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.

hs-coerce HTML list case: use outerHTML for element items, not str.
hs-coerce Fragment case: actually build a DocumentFragment — element
items are appended directly; strings are parsed via a temp div.

Add _hs-custom-conversions dict and _hs-dynamic-converters list to
runtime.sx. hs-set-conversion!/hs-clear-conversion!/hs-add-dynamic-converter!/
hs-pop-dynamic-converter!/hs-clear-converters! helpers expose the API.
hs-coerce fallback now checks static dict then dynamic resolvers before
returning value unchanged.
Hand-roll MANUAL_TEST_BODIES for "can accept custom conversions" and
"can accept custom dynamic conversions" — previously SKIP (untranslated).

Parser: add 'the ...' as a recognized transition target in parse-transition-cmd's
tgt cond, enabling 'transition the next <div/>'s *width from A to B'.
Generator MANUAL_TEST_BODIES for 4 previously-SKIP tests:
- can transition on query ref with possessive (transition suite, 17/17)
- can write to next element with put command (relativePositionalExpression, 23/23)
- parse error at EOF on trailing newline does not crash (core/parser, 13/14)
- halt works outside of event context (halt suite, 7/7)
Also fix hs-kernel-eval.js navigator assignment for Node.js v22 (read-only global).

parse-feat true fallback now routes directly to parse-cmd-list when the first
token is a keyword (e.g. "add - to"), so command-keyword scripts always produce
parse errors rather than being treated as subtraction expressions. Non-keyword
tokens (numbers, identifiers, paren-open) still try expression-first.
