Krzysztof kuhy Rudnicki bca70b67b5 Shell coverage: convert the ratchet to a measured 100% bar
The gate was a presence check -- 'a run_all.sh exists beside this lib' --
which an empty suite that asserts nothing satisfies. It now measures.

100% is reachable with no suppressions and no production source changes:
run the suite inside a user+mount namespace and the sudo-writes, systemd
units and nftables rules execute for real against a throwaway /etc.

- meta/scripts/shell_coverage_jail.sh: the runner, promoted out of a
  session scratchpad. Two fixes it needed on the way: bind targets mirror
  the real directory tree (an empty bind makes writes fail with ENOENT,
  which reads as unreachable code), and sudo gets a pass-through stub
  because real sudo cannot setresuid inside a userns.
- It fingerprints git status before and after and fails the run if a
  write escapes the jail. Verified with a deliberate escapee.
- dot_resolver_install.sh: 39/39 = 100.00%, 28 assertions. Picked by
  scoring every allowlisted lib on root ops, system writes and
  destructive calls -- it scored highest in the repo. Allowlist 106 -> 105.
- jscpd was already over its own threshold at 2.45% and would have
  rejected every commit staging a .sh file. Excluding vendored .venv/
  shell alone gives 1.67%; also excluding lib/tests/ gives 1.47%.

The gate is deliberately NOT wired into the hook chain yet.
