Add 9player and introspect as programs beside the library

9player/: FUSE mount CLI that mounts a 9P2000 tree into a fresh user+mount
namespace and runs a program in it (no root, no libfuse, no libc).
introspect/: the 9P debug/introspection library (freestanding core, value
renderers, Linux probe with threads/stacks/memory/breakpoints/panics) and
its demo server. Each has its own build fragment; the root build.zig wires
them behind -D9player/-Dintrospect with namespaced steps (9player-itest,
introspect-check-freestanding, programs-test, ...) and exports the
introspect module for dependents. This is the layout for related programs.
