test-signals.sx: 17 tests covering signal basics (create, deref, reset!,
swap!), computed (derive, update, chain), effects (run, re-run, dispose,
cleanup), batch (deferred deduped notifications), and defisland (create,
call, children).
types.py: Island dataclass mirroring Component but for reactive boundaries.
evaluator.py: sf_defisland special form, Island in call dispatch.
run.py: Signal platform primitives (make-signal, tracking context, etc)
and native effect/computed/batch implementations that bridge Lambda
calls across the Python↔SX boundary.
signals.sx: Updated batch to deduplicate subscribers across signals.

Tests cover page data cache, optimistic cache update/revert/confirm,
offline connectivity tracking, offline queue mutation, and offline-aware
routing. Registered in test runner with mocked platform functions.

Add page-render-plan to deps.sx: given page source + env + IO names,
computes a dict mapping each needed component to "server" or "client",
with server/client lists and IO dep collection. 5 new spec tests.
Integration:
- PageDef.render_plan field caches the plan at registration
- compute_page_render_plans() called from auto_mount_pages()
- Client page registry includes :render-plan per page
- Affinity demo page shows per-page render plans

Add :affinity :client/:server/:auto annotations to defcomp, with
render-target function combining affinity + IO analysis. Includes
spec (eval.sx, deps.sx), tests, Python evaluator, and demo page.
Fix critical bug: Python SX parser _ESCAPE_MAP was missing \r and \0,
causing bootstrapped JS parser to treat 'r' as whitespace — breaking
all client-side SX parsing. Also add \0 to JS string emitter and
fix serializer round-tripping for \r and \0.
Reserved word escaping: bootstrappers now auto-append _ to identifiers
colliding with JS/Python reserved words (e.g. default → default_,
final → final_), so the spec never needs to avoid host language keywords.

test.sx now defines deftest/defsuite as macros. Any host that provides
5 platform functions (try-call, report-pass, report-fail, push-suite,
pop-suite) can evaluate the file directly — no bootstrap compilation
step needed for JS.
- Added defmacro for deftest (wraps body in thunk, catches via try-call)
- Added defmacro for defsuite (push/pop suite context stack)
- Created run.js: sx-browser.js evaluates test.sx directly (81/81 pass)
- Created run.py: Python evaluator evaluates test.sx directly (81/81 pass)
- Deleted bootstrap_test_js.py and generated test_sx_spec.js
- Updated testing docs page to reflect self-executing architecture
