`codex mcp add -c` argument does nothing.

Update - this bug report is in error, -c is not specific to the codex mcp add command.

Closing now.

~~## Issues with codex mcp add command arguments~~

~~* --config / -c does not work at all to set values, including cwd.~~
~~* Does not prevent usage of stdio only arguments like --env when the MCP server being added has the --url flag.~~
~~* Command does not support --cwd.~~
~~ * For ease of use, I think most users would appreciate it if this was an explicit option just like --env is.~~
~~ * This is especially painful since -c does not seem to work.~~

~~### What steps can reproduce the bug?~~

~~``~~
~~# step 1 - add a dummy "mcp server" and use the -c flag, exactly like is shown in codex mcp add --help`~~

~~$ codex mcp add test123 '-c model=o3' -- sleep 123~~
~~Added global MCP server 'test123'.~~

~~# step 2 - check on the "mcp server" that was added to the codex config~~
~~# notice that nothing was set, the -c flag did nothing.~~

~~$ tail ~/.codex/config.toml~~
~~[mcp_servers.test123]~~
~~command = "sleep"~~
~~args = ["123"]~~
~~```~~

~~### What is the expected behavior?~~

~~```~~
~~$ codex mcp add test123 '-c model=o3' -- sleep 123~~
~~Added global MCP server 'test123'.~~

~~$ tail ~/.codex/config.toml~~
~~[mcp_servers.test123]~~
~~command = "sleep"~~
~~args = ["123"]~~
~~model = "o3"~~
~~```~~
