Add `Snacks.util.lsp.on()` to register handlers that fire when LSP clients
attach with specific capabilities. Supports filtering by:
- LSP method/capability
- Client name
- Buffer ID
- Any vim.lsp.get_clients() filter
Features:
- Handles both LspAttach and client/registerCapability events
- Ensures handlers only fire once per buffer
- Lazy-loaded via Snacks.util metatable
This provides a foundation for LSP-aware features like conditional keymaps.

## Description
In certain filesystems — such as bind mounts, NFS, FUSE, or other
mounted paths — uv.fs_scandir_next() may return a nil type for valid
directories. This causes the snacks.nvim explorer to treat mounted
folders as files, making them unexpandable in the UI.
This patch adds a fallback to resolve the correct type when
fs_scandir_next() returns nil. It uses uv.fs_stat() first, and falls
back to vim.fn.isdirectory() if needed.
This ensures that mounted directories are properly marked as navigable.
Code change summary:
- Inside Tree:expand, we now check t == nil
- If so, we call uv.fs_stat() to get the true type
- If fs_stat fails, we fallback to vim.fn.isdirectory
- Final dir = true logic remains intact
Impact:
- Fixes a long-standing bug in mounted directories under /mnt, FUSE,
etc.
- Only runs extra checks when needed (no performance hit for regular
files)
- No changes elsewhere — clean, isolated patch
