Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to A specially named devcontainer configuration directory can inject commands into the host when connecting through WezTerm, potentially executing with the current user's privileges; Neovim may also close before reporting unsupported terminal failures. Merge should wait for safe argument-based command construction and corrected connection failure handling. Sequence Diagram(s)sequenceDiagram

In `@lua/devcontainer-cli/folder_utils.lua`:
- Line 153: Update the trailing-comma cleanup around table.concat(out) so commas
are removed only when they occur outside JSON string literals; track string
state while scanning the comment-stripped content and preserve escaped quotes
correctly. Add a regression test covering a name value containing commas
immediately before } or ].
In `@README.md`:
- Line 109: Update the documented command to match the registered
DevcontainerToggle spelling in lua/devcontainer-cli/init.lua, preserving the
command’s existing usage while correcting its capitalization.
- Line 118: Update the fenced code block beginning at the referenced README
section to include the text language identifier, changing its opening fence to a
text fence while preserving the block contents.

At my workplace, we use multiple devcontainer configurations per repository, to differentiate between test and code development environments. These multiple configs are as per the spec: https://containers.dev/implementors/spec/#devcontainerjson. However, this was not working yet for this plugin, which is the reason for this PR.
I have made sure that when only 1 .devcontainer.json config exists, that config should be automatically picked. There should be no breaking changes in this PR.
I have used LLMs extensively for this PR, as I am not proficient in lua. I have tested the result on my own machine, running Ubuntu in WSL with tmux. If this does not meet your contribution guideline, or the code in general does not meet your quality criteria, please let me know.
