mcp-config: write the sync hook to ~/.zshrc.local, not ~/.zshrc

Browse Source 
~/.zshrc is MANAGED: zsh/install.sh overwrites it wholesale (cp) on every
bootstrap run. install.sh appended the mcp-sync hook to that same file, so
the next bootstrap silently deleted it -- sync.sh then never ran, so
OPENCODE_CONFIG was never exported and opencode came up with no models and
no skills. It looked like a broken gateway or a bad model; it was a wiped
shell hook.

~/.zshrc.local is the unmanaged file the managed zshrc sources last, so the
hook now survives a re-bootstrap. Verified: hook lands in ~/.zshrc.local
(0600), managed ~/.zshrc is left untouched, and OPENCODE_CONFIG still
exports after simulating the bootstrap overwrite.

Also warn instead of failing silently when python3 is missing: sync.sh then
deploys the base config verbatim with an EMPTY models map, which presents as
"the gateway has no models" rather than "a dependency is absent".
