feat(installer): add guided zeroclaw installer and distro hardening (#887)

* feat(installer): add guided zeroclaw installer entrypoint

- add top-level POSIX wrapper (zeroclaw_install.sh) that ensures bash is present

- route bootstrap/install compatibility scripts through the new installer entrypoint

- improve Linux dependency handling for Alpine/Fedora/Arch, including pacman container fallback

* fix(ci): resolve dependabot config conflict and run daily

- remove duplicate docker ecosystem entry with overlapping directory/target-branch

- switch cargo, github-actions, and docker schedules from monthly to daily

.github/dependabot.yml
