install.sh aborted with npm EEXIST when claude was already present:
the binary is a native-installer symlink (~/.local/bin/claude ->
~/.local/share/claude/versions/*) that npm does not own, and the
npm prefix (~/.local, set for BLK-013) targets the same path. The
`else err` branch turned EEXIST into a fatal exit. No presence guard
existed, unlike the RTK/GSD steps.
- install.sh: skip-if-present guard (command -v claude), mirroring
the RTK/GSD pattern; npm only runs on a truly fresh machine.
- update-all.sh: pick updater by channel — npm for npm-managed
installs, `claude update` for native installs (npm would EEXIST).

Fresh machine had no npm → install.sh err-exited before the Claude Code
CLI install could run. Instead of aborting, bootstrap the current LTS via
nvm (v0.39.7) → `nvm install --lts` when node or npm is absent. Keeps the
>=18 floor + friendly messages on hard failure.
Replaces the reverted lib/install-prereqs.sh centralization with the
minimal targeted fix.

Previously untracked. Called by make install for first-time setup:
installs Claude Code CLI, authenticates, inits submodules, symlinks,
and runs plugin installer.
