fix(ocp-connect): write ~/.zshrc on macOS (default shell since Catalina)

macOS default shell has been zsh since Catalina (2019). The previous
rc-file selection logic treated macOS the same as Linux, so on a fresh
Mac where ~/.zshrc did not already exist AND the script was invoked via
`bash -s --` (e.g. `curl | bash`), the $SHELL guard was `/bin/bash`
and neither condition for zshrc was true — resulting in only ~/.bashrc
being written. Since ~/.bashrc is not sourced by interactive zsh
sessions, the OPENAI_BASE_URL / OPENAI_API_KEY exports were invisible
to interactive shells.

Fix:
- Add an explicit `elif $is_mac` branch that unconditionally includes
  ~/.zshrc: create the file (empty) if it does not yet exist, since
  zsh tolerates an empty ~/.zshrc.
- On macOS, ~/.bashrc is only written if it already exists — consistent
  with the task spec ("don't create ~/.bashrc if it didn't exist").
- Linux path is preserved unchanged.
- Fix the "Reload your shell" hint at script end: previously it printed
  only the last loop variable `$rc_file` (stale reference outside the
  loop). Now it iterates `${rc_files[@]}` so both files are shown on
  macOS (reproducing the Round A bug: hint said only `source ~/.bashrc`
  even when zshrc should also be reloaded).

Smoke-tested with HOME=/tmp/fakehome redirect for three scenarios:
  1. Fresh MacBook (no .bashrc, no .zshrc)  → only .zshrc created+written
  2. macOS with existing .bashrc             → both .bashrc and .zshrc written
  3. Linux with bash, no .bashrc             → .bashrc written (unchanged)

Identified during Round A testing on MacBook 2026-05-08.
