chore: name no local tool folders in the ignore files

The git and docker ignore files and the lint config listed the folders
and notes of particular editors and tools. Local workspace folders
belong in a contributor's own global excludes. The image copies only
named paths, so nothing local reaches it, and the lint config now skips
every hidden top-level folder, which covers local worktrees under any
name; no tracked hidden folder holds code.
