jj config set --repo user '{ name = "Some One", email = "[email protected]" }' creates an invalid configuration file

[forivall]

Description

Using a toml inline table for local repo user configuration creates a broken configuration file.

Steps to Reproduce the Problem

1. Run jj config set --repo user '{ name = "Some One", email = "[email protected]" }'
2. Use any other jj command.

Expected Behavior

The jj command should work, and the configured inline user table should work

.jj/repo/config.toml

user = {name = "Some One", email = "[email protected]"}

Actual Behavior

Config error: Value not found for user.name
For help, see https://jj-vcs.github.io/jj/latest/config/.

I had to manually edit the file to revert the change to a regular TOML table. (I wanted to create a single command or alias which uses a single jj command to be able to set my per-repo user, as a workaround for #5280)

Specifications

• Platform: macOS 15.2
• Version: jj 0.25.0

The underlying issue (or design decision) is the same as #5255
