Reset to last known-good state (908f4f80) where links, stepper, and
islands all work, then recovered all hyperscript implementation,
conformance tests, behavioral tests, Playwright specs, site sandbox,
IO-aware server loading, and upstream test suite from f271c88a.
Excludes runtime changes (VM resolve hook, VmSuspended browser handler,
sx_ref.ml guard recovery) that need careful re-integration.

Two hyperscript extensions beyond stock:
render ~component :key val [into|before|after target]
Tokenizer: ~ + ident → component token type
Parser: render command with kwargs and optional position
Compiler: emits (render-to-html ~comp :key val) or
(hs-put! (render-to-html ...) pos target)
Bridges hyperscript flow to SX component rendering
eval (sx-expression) — SX escape hatch
Inside eval (...), content is SX syntax (not hyperscript)
Parser: collect-sx-source extracts balanced parens from raw source
Compiler: sx-parse at compile time, inlines AST directly
Result: SX runs in handler scope — hyperscript variables visible!
Also supports string form: eval '(+ 1 2)' for backward compat
set name to "Giles"
set greeting to eval (str "Hello " name) -- name is visible!
16 new tests (parser + compiler + integration).
3127/3127 full build, zero regressions.

Tokenizer:
* and % now emit as operators (were silently swallowed)
Added keywords: install, measure, behavior, called
5 new arithmetic operator tests
Parser — expression layer:
Arithmetic (+, -, *, /, %) via parse-arith
Unary not, no, unary minus
the X of Y possessive (parse-the-expr)
as Type conversion, X in Y membership, array literals [...]
fetch URL parsing fixed — no longer consumes "as" meant for fetch
Parser — 8 new commands:
return, throw, append...to, tell...end, for...in...end,
make a Type, install Behavior, measure
Parser — 2 new features:
def name(params)...end, behavior Name(params)...end
Parser — enhanced:
wait for event [from target], on every event modifier
33 new parser tests (16 suites), 5 tokenizer tests.
3043/3043 full build, zero regressions.

lib/hyperscript/parser.sx — parses token stream from hs-tokenize into
SX AST forms. Covers:
Commands: add/remove/toggle class, set/put, log, hide/show, settle
Events: on with from/filter, command sequences
Sequencing: then, wait (with time units)
Conditionals: if/then/else/end
Expressions: property chains, it, comparisons, exists, refs
DOM traversal: closest, next, previous
Send/trigger events to targets
Repeat: forever, N times
Fetch/call with argument lists
55 tests across 12 suites. 3005/3005 full build, zero regressions.
