Update codex and claude-code inputs
Check shared dirs: link, target, manifest, and removal on undeclare
Add launchers.<cmd>.sharedDirs: share a state-dir directory between launchers
Launchers with different ids share nothing, which is right for logins but
not for Claude's projects (sessions and memory) or Codex's memories. A
shared dir is a managed symlink to the other launcher's copy, created on
demand so the link holds whichever launcher starts first, and removed with
the declaration while the data stays.
Add claude.mcpServers: MCP servers loaded with --mcp-config
The flag is variadic, so it goes first and --settings always follows it;
otherwise a prompt after it would be read as another config file. Logins
stay in the account.

Describe --model in the companions skill
The Claude Code call now says how to pick a model: an alias (fable, opus,
haiku) for the latest of a family or a full name to pin a version. The
companions check greps the generated skill for the flag.
