feat(deploy): move app URL to /human-machine-strata + 301 from the legacy path

Build default app-path → /human-machine-strata; deploy.sh APP_PATH default too.
_write_redirects now emits a permanent redirect /human-experience-simulator/* →
/human-machine-strata/:splat so old links still land. Media (R2 bucket) + Pages
project names are unchanged (not in the benstull.art URL). Updated the build
test (asserts the legacy redirect) + static-build e2e path + README paths.
