0ba7ebe349 Phase 2: IO detection & selective expansion in deps.sx 
Extend the spec with IO scanning functions (scan-io-refs, transitive-io-refs,
compute-all-io-refs, component-pure?) that detect IO primitive references in
component ASTs. Components are classified as pure (no IO deps, safe for client
rendering) or IO-dependent (must expand server-side).

The partial evaluator (_aser) now uses per-component IO metadata instead of
the global _expand_components toggle: IO-dependent components expand server-
side, pure components serialize for client. Layout slot context still expands
all components for backwards compat.

Spec: 5 new functions + 2 platform interface additions in deps.sx
Host: io_refs field + is_pure property on Component, compute_all_io_refs()
Bootstrap: both sx_ref.py and sx-ref.js updated with IO functions
Bundle analyzer: shows pure/IO classification per page

4c97b03dda Wire deps.sx into both bootstrappers, rebootstrap Python + JS 
deps.sx is now a spec module that both bootstrap_py.py and bootstrap_js.py
can include via --spec-modules deps. Platform functions (component-deps,
component-set-deps!, component-css-classes, env-components, regex-find-all,
scan-css-classes) implemented natively in both Python and JS.

- Fix deps.sx: env-get-or → env-get, extract nested define to top-level
- bootstrap_py.py: SPEC_MODULES, PLATFORM_DEPS_PY, mangle entries, CLI arg
- bootstrap_js.py: SPEC_MODULES, PLATFORM_DEPS_JS, mangle entries, CLI arg
- Regenerate sx_ref.py and sx-ref.js with deps module
- deps.py: thin dispatcher (SX_USE_REF=1 → bootstrapped, else fallback)
- scan_components_from_sx now returns ~prefixed names (consistent with spec)

Verified: 541 Python tests pass, JS deps tested with Node.js, both code
paths (fallback + bootstrapped) produce identical results.

2866bcbfc3 Implement isomorphic Phase 1: per-page component bundling
All checks were successful
Build and Deploy / build-and-deploy (push) Successful in 4m43s
Details 
Add component dependency analyzer (shared/sx/deps.py) that walks
component AST bodies to compute transitive dependency sets. sx_page()
and sx_response() now send only the components each page needs instead
of the entire registry.

Changes:
- New: shared/sx/deps.py — transitive_deps(), components_needed(),
  scan_components_from_sx(), compute_all_deps()
- shared/sx/types.py — Add deps: set[str] field to Component
- shared/sx/jinja_bridge.py — Compute deps on registration, add
  components_for_page() and css_classes_for_page()
- shared/sx/helpers.py — sx_page() uses per-page bundle + hash,
  sx_response() passes source to components_for_request() for
  page-scoped component diffing
- New: shared/sx/tests/test_deps.py — 15 tests covering AST scanning,
  transitive deps, circular refs, per-page bundling
