KeiSei84 abae256c1d feat(install): opt-in hook packs + stack profiles (public posture)
A fresh install now activates only the safety pack; discipline hooks and
agents are opt-in via an onboarding step (step 6) or `kei configure`.
"People don't need Rust-only" — they pick their own stack.

- _primitives/hook-packs.toml: SSoT mapping pack -> hooks, stack -> packs +
  agent groups. safety always on; evidence/observability/epistemic/
  orchestration/git-guard/stack-rust opt-in. rust-first/no-python only under
  the systems stack; git-guard (no-github-push) opt-in only, pulled by no stack.
- lib-profile: extract generic _toml_array (reused by lib-packs); profile_members
  becomes a thin wrapper (no behavior change).
- lib-packs: pack/stack/agent resolvers + selection loader.
- lib-hooks: filter_snippet_by_packs (install-time allowlist) + prune_kit_hooks
  (reconfigure removes deselected kit hooks, keeps foreign ones); activate_hooks
  rewired to prune + filter + merge. No custom settings.json fields (/doctor safe).
- lib-agents: install_manifests filters by stack agent set (empty = install all).
- onboarding: pick_stack step (reuse _onb_read_choice), persists stack_profile +
  enabled_packs to onboarding.toml; i18n STR_* added.
- bin/kei configure -> scripts/kei-configure.sh (re-pick without reinstall);
  install stamps ~/.claude/.kei-kit-dir.
- numeric-claims-guard: money regex no longer matches shell positionals ($1..$9);
  requires decimal / unit / 2+ digits / tilde. Real money + time still caught.
- gate one-liner added to 8 discipline hooks (runtime toggle via hooks-control).

Verified end-to-end (scratch HOME): fresh=safety only; evidence pack adds
numeric+citation; systems stack wires rust-first + 14 base/systems agents (no
data-science/swift); reconfigure-shrink prunes kit hooks but keeps a foreign
hook; settings schema clean; assembler golden 3/3.
