Search the command list when adding a keybinding

[ChristianEllehammer]

Problem / use case

In Settings → Keybindings → Add keybinding, the "Command" picker is a long scrolling list with no way to filter it. Finding one command means scrolling past every other one. The "Search keybindings" box at the top of the page filters the rows below, not this list.

Proposed behavior

Make the picker searchable. Typing "sea" narrows it to "Project Search: Toggle". Matching covers the command label and the command id, so sidebar.toggle finds it as well as "Sidebar: Toggle".

Working proof

No PR yet. A small working version is on my fork:

• commit
• branch

It swaps Select for the existing shared Combobox (the same pattern as the composer code-language picker) in NewKeybindingCommandSelect, and adds a small filter helper with a unit test. Three files, web only, no contract or server changes. The focused tests, typecheck, lint and format check pass, and I tried it in the web client. I have not tried it in the desktop app.

Would you approve an XS PR with this scope?

Duplicate check

I searched Ideas discussions, issues and PRs (open and closed) and found no identical proposal. The closest are:

• Search keybindings by pressing a shortcut to find existing assignments #17510 proposes searching keybindings by pressing a shortcut. It is about the page search, not the add-binding command picker.
• Focus Keybindings search when opened from the command palette or Settings search #15312 proposes focusing the page search on entry. Same page, different control.
• [Feature]: Add search to project pickers #8608 added search to the project pickers. Same kind of change for a different picker.
