meson/ninja/capnp/Go only exist inside the hermetic nix dev shell, but
xce-build.sh never entered it itself -- the /xce-build skill documented
wrapping every invocation in `nix develop ./src --command ...` by hand,
so a bare `bash src/tools/xce-build.sh ...` (run directly instead of
through the skill) failed opaquely with "meson: command not found". This
was a recurring, previously-logged gap that resurfaced again today mid
bug-1789 verification.
The script now checks IN_NIX_SHELL at the top and re-execs itself under
`nix develop` if unset, so every caller -- the skill, a bare invocation,
CI, a human at a terminal -- gets it automatically. A nested call (already
inside the shell) is a no-op past that check. README.md's daily-develop
section updated to match; the old "or use nix develop --command" example
is now redundant and removed.

Adds the previously-uncommitted spec.json/requirements.md/design.md/research.md
for scheduler-snapshot-job-allocation (feature now fully implemented across
tasks 1.1-4.5) and the in-progress xce-test-cli-ux spec's requirements.md/
spec.json. Updates brief.md, a security.md note on an unrelated deferred RBAC
persistence gap found during this feature's cross-component survey, and syncs
OpenWolf's anatomy/memory/token-ledger/daemon-log bookkeeping.
