fix(zsh): move dotDir to XDG (~/.config/zsh), preserve history
CI / flake (pull_request) Successful in 2m21s
Details

Browse Source 
Set programs.zsh.dotDir to ~/.config/zsh, adopting the new home-manager
default and silencing the dotDir deprecation warning on rebuild. Pin
history.path to the existing ~/.zsh_history so the move doesn't orphan it,
and extend the zcompdump-reset activation to the new $ZDOTDIR location
(legacy $HOME and cache paths still swept). README updated.

| History | 100k in-memory/on-disk, deduped, space-prefixed commands ignored, timestamped, **shared live across sessions** |
| History substring search | type a fragment, then ↑/↓ cycles matching past commands — works in foot, iTerm2 and the Linux TTY (both CSI and SS3 arrow encodings bound) |
| Prompt | hostname is prefixed when over SSH |
