fix(vscode): stop code action providers from interfering with quick fixes

[markijbema]

Summary

• Gate AutocompleteCodeActionProvider behind the enableSmartInlineTaskKeybinding setting so it stops injecting a "Suggested Edits" QuickFix into every Ctrl+. / Cmd+. menu when autocomplete is disabled
• Remove isPreferred from "Fix with Kilo Code" code action so it doesn't hijack VS Code's auto-fix over language server fixes that provide actual code edits

Context

This is a follow-up to #8508 which fixed the keybinding conflict (the cycleAgentMode command was globally bound to Ctrl+./Cmd+. without a when clause). That fix addressed the primary breakage, but two code action provider issues remained:

1. AutocompleteCodeActionProvider was registered with "*" document selector and unconditionally returned a QuickFix action on every provideCodeActions call — regardless of whether autocomplete was enabled, adding noise to every quick fix menu
2. KiloCodeActionProvider marked "Fix with Kilo Code" as isPreferred: true, which caused it to be selected by editor.action.autoFix over language server fixes that provide actual inline code edits (Kilo's action opens a chat, not a direct fix)

Closes #8522

Test plan

• Existing unit tests updated and passing (bun test tests/unit/code-action-provider.test.ts — 13 pass)
• With autocomplete disabled: Ctrl+. menu no longer shows "Kilo Code: Suggested Edits"
• With autocomplete enabled: "Kilo Code: Suggested Edits" still appears as before
• editor.action.autoFix no longer selects "Fix with Kilo Code" over actual language server fixes
