David Alecrim 2bdf1fca20 command_palette: Fix keymap editor not matching actions with underscored namespaces (#50415)
Closes https://github.com/zed-industries/zed/issues/50223

## Summary

When clicking **Change Keybinding** from the command palette on an
action whose namespace contains underscores (e.g.
`terminal_panel::Toggle`, `project_panel::ToggleFocus`), the keymap
editor showed **"No matches found for the provided query"**. Actions
without underscores (e.g. `zed::OpenLog`) worked fine.

I opened this issue for this
https://github.com/zed-industries/zed/issues/50223, but took the liberty
of sending a PR.

**Root cause:** `normalize_action_query` preserved underscores in the
query, but the search candidates are built with `humanize_action_name`
which converts underscores to spaces. The fuzzy matcher looked for `_`
in a candidate like `"terminal panel: toggle"` where it doesn't exist,
so matching always failed.

**Fix:** `normalize_action_query` now converts underscores to spaces
before the deduplication checks, consistent with `humanize_action_name`.
This also correctly collapses consecutive underscores with adjacent
spaces.

All three call sites of `normalize_action_query` (command palette
search, keymap editor filter, action completion provider) match against
humanized candidates, so the fix improves consistency across all of
them.

Release Notes:

- Fixed keymap editor showing no results when opening "Change
Keybinding" from the command palette for actions with underscores in
their namespace (e.g. `terminal_panel::Toggle`,
`project_panel::ToggleFocus`)

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
