Browse Source 
Moves the existing virtual-thread/context-propagation project into
context-propagation/ and adds method-security/ for the Spring Security 7
method-security article: nine runnable demos, fourteen assertions, and every
transcript the article quotes, regenerated by scripts/run-all.sh.

=== Demo 5: ReactiveSecurityContextHolder vs. ThreadLocal across a scheduler hop ===
A) SecurityContextHolder (ThreadLocal), no scheduler hop: authenticated as alice
B) SecurityContextHolder (ThreadLocal), AFTER publishOn to a different thread: NO AUTHENTICATION (lost) [proves ThreadLocal doesn't survive a scheduler hop]
C) ReactiveSecurityContextHolder + contextWrite, no scheduler hop: Hello, carol
D) ReactiveSecurityContextHolder + contextWrite, AFTER publishOn to a different thread: Hello, dave [Context travels with the stream, not the thread]
E) getProfile() with no contextWrite() upstream at all: Anonymous [defaultIfEmpty fires; getContext() completes empty, it does not error]
