mcp-config: put the shell hook in ~/.zshrc.local on a fresh box

Browse Source 
install.sh chose the rc file from $SHELL. On a fresh box bootstrap runs
from the user's original bash: zsh/ has already switched the login shell
to zsh, but $SHELL in that process still says bash. The hook went into
~/.bashrc, below zsh/'s auto-exec hook, so every new terminal exec'd into
zsh before reaching it, sync.sh never ran, OPENCODE_CONFIG was never
exported, and opencode came up unconfigured. Boxes already on zsh were
fine, which is why it only showed up on a new machine.

Now the dotfiles-managed ~/.zshrc, or zsh as the account's login shell
(getent), selects ~/.zshrc.local regardless of $SHELL. Standalone
`curl | sh` installs without these dotfiles behave as before.

Reproduced and verified in a clean ubuntu:24.04 container (zsh/ then
mcp-config/, dummy key): before, hook in .bashrc and OPENCODE_CONFIG
unset in a new zsh; after, hook in .zshrc.local and OPENCODE_CONFIG
points at a config with the covert-gpt provider and gitea/proxmox MCP
servers. A box already broken this way is repaired by re-running the
module, and re-runs leave a single hook.
