- _handle_memory_read: pass the request-owned get_config_snapshot() into
_external_notes_sources_enabled() so no ambient/process-global config is
re-read later in the handler (review requirement).
- tests: add cross-profile forced-reload regressions for both directions
(A disabled/B enabled and inverse), covering memory_enabled and
user_profile_enabled for read (no content/path/mtime) and write (403 +
byte-identical file).
- tests: adapt _external_notes_sources_enabled mock arity in
test_3866_project_context_memory_section.py to the new snapshot param.
Browser race in static/ui.js: _autoScrollFollow can be undefined when
scroll/scrollpin listeners fire before boot.js initializes settings.
Bare global reference (ReferenceError) occurs on the golden path.
Fix: wrap both consumer sites with a typeof guard that defaults to
true (matching the boot.js fallback) when the variable hasn't been set.
Closes#6606
