* fix(nushell): adapt the completer to the 0.116 contract
Nushell 0.116 runs an external completer on a background worker
without the terminal unless the registered closure reaches a
command carrying the @interactive attribute. Interactivity is
seen through the closure to the command it calls, so wrap the
completion logic in an @interactive entry point and register a
closure that ends with the call to it.
Read the named `place` input instead of the deprecated
positional `spans`; $place.command carries the same token list.
An @interactive completer cannot decline with null (null reads
as a dismissed picker), so request the fallback explicitly when
the `**` trigger is absent, keeping plain file completion
working. The previous external completer is still called when
the trigger is absent.
The script now requires Nushell 0.116+, since @interactive is a
parse error on older versions.
Fixes#4932
* fix(nushell): retry the previous completer with the legacy spans input
The fallback to the previously configured external completer always
handed it the new `place` input. A completer that still declares the
legacy `spans` parameter errors on a record, so the fallback silently
produced no completions for pre-0.116 completers (e.g. older Carapace
installs).
Try `place` first, then retry with the token list, which is what the
old positional bridge handed such completers.
* docs(nushell): note the 0.116 requirement and load order
Requires Nushell 0.116.1+, where a completion can take the terminal
through the @interactive attribute, and the wrapper captures the
external completer present at load time.
