Buttons clicked before hydration get a subtle pulse animation
(sx-pending class) showing the click was captured. The animation
is removed when the click is replayed after hydration, or cleared
on boot completion as a fallback.

The parser was reporting "Unexpected char: )" with no position info.
Added line number, column, and byte position to all parse errors.
Root cause: bind-sse-swap had one extra close paren that naive paren
counting missed because a "(" exists inside a string literal on L1074
(starts-with? trimmed "("). Parse-aware counting (skipping strings
and comments) correctly identified the imbalance.

- ocaml_sync.py: escape newlines in eval/load_source to prevent
protocol desync (bridge crashed on any multi-line SX)
- Stepper: do-back uses rebuild-preview (O(1) render) instead of
replaying all steps. Hydration effect same. Cookie save on button
click only.
- dom.sx: remove duplicate dom-listen (was shadowing the one at
line 351 that adapter-dom.sx's dom-on wraps)
- orchestration.sx: fix bind-sse-swap close paren count
- safe_eq: Dict equality via __host_handle for DOM node identity

adapter-dom.sx defines dom-on as a wrapper around dom-listen (adds
post-render hooks). But dom-listen was never defined — my earlier
dom-on in dom.sx was overwritten by the adapter's version. Rename
to dom-listen so the adapter's dom-on can call it.
This fixes click handlers not firing on island buttons (stepper,
stopwatch, counter, etc.).

Platform:
- sx-platform.js: extract ?v= query from script tag URL, append to
all .sx file XHR requests. Prevents stale cached .sx files.
Stepper performance:
- do-back: use rebuild-preview (pure SX→DOM render) instead of
replaying every do-step from 0. O(1) instead of O(n).
- Hydration effect: same rebuild-preview instead of step replay.
- Cookie save moved from do-step to button on-click handlers only.

Clicks on island elements before hydration completes are captured
and replayed after boot finishes:
- shell.sx: inline script (capture phase) buffers clicks on
[data-sx-island] elements that aren't hydrated yet into window._sxQ
- boot.sx: after hydration + process-elements, replays buffered clicks
by calling target.click() on elements still connected to the DOM
This makes SSR islands feel interactive immediately — the user can
click a button while the SX kernel is still loading/hydrating, and
the action fires as soon as the handler is wired up.

- Add wasm_hash (MD5 of sx_browser.bc.js) to shell template
- Script tags: /wasm/sx_browser.bc.js?v={hash}, /wasm/sx-platform.js?v={hash}
- Pass wasm_hash through helpers.py and ocaml_bridge.py
- Fix missing close paren in bind-sse-swap (broke SX parsing)

The DOM adapter treated all Dict values as empty (create-fragment).
But DOM nodes (text nodes, elements) from create-text-node/host-call
are wrapped as Dict { __host_handle: N } by js_of_ocaml. Now checks
for __host_handle and passes them through as DOM nodes.
Fixes stopwatch button text ("Start") and timer display ("0.0s")
which were missing because create-text-node results were discarded.

Navigation pipeline now works end-to-end:
- outerHTML swap uses dom-replace-child instead of morph-node (morph has
a CEK continuation issue with nested for-each that needs separate fix)
- swap-dom-nodes returns the new element for outerHTML so post-swap
hydrates the correct (new) DOM, not the detached old element
- sx-render uses marker mode: islands rendered as empty span[data-sx-island]
markers, hydrated by post-swap. Prevents duplicate content from island
body expansion + SX response nav rows.
- dispose-island (singular) called on old island before morph, not just
dispose-islands-in (which only disposes sub-islands)
OCaml runtime:
- safe_eq: Dict equality checks __host_handle for DOM node identity
(js_to_value creates new Dict wrappers per call, breaking physical ==)
- contains?: same host handle check
- to_string: trampoline thunks (fixes <thunk> display)
- as_number: trampoline thunks (fixes arithmetic on leaked thunks)
DOM platform:
- dom-remove, dom-attr-list (name/value pairs), dom-child-list (SX list),
dom-is-active-element?, dom-is-input-element?, dom-is-child-of?, dom-on
All 5 reactive-nav Playwright tests pass.
