Deprecate shell command and hide from help output#243
Merged
Conversation
Hide both `mcpc shell @<session>` and `mcpc @<session> shell` from `--help` output, and print a deprecation warning to stderr when the command is invoked. The command itself still works. Also drop the `mcpc <target> shell` hint from the "Available commands" list shown by `mcpc @<session>` so we stop advertising it.

Resolves a README.md conflict from #243 (shell command deprecation) by adopting main's help block — the `shell <@session>` row is gone from `mcpc --help`. Also removes docs/vhs/shell.tape and its references from docs/vhs/README.md and docs/vhs/mcpc-demo.tape so the templates don't showcase a now-deprecated command. Refs #242, #243
