feat: introduce shortcuts and shell hook support

- **Shortcuts**: Add hostname normalization with domain stripping and hyphen folding. Include alias generation for cached hosts.
- **Shell Hook**: Automate 24h cache refresh trigger with shell startup hook. Add install/uninstall commands for bash, zsh, and fish.
- **Wizard**: Extend setup wizard to configure shortcuts (domains, hyphen stripping) and default SSH port.
- **Cache**: Add `GetByShortcut` for resolving hosts via normalized shortcuts. Implement `NeedsRefresh` / `SetRefreshed` logic for refresh timestamps.
- **Tests**: Comprehensive unit tests for shortcuts, hook installation, cache refresh, and alias generation.
- **Docs**: Update README with shortcuts, shell hook, and default SSH port configuration.

 netssh -l ops my-router        # -l flag wins      → ssh -l ops 10.0.0.1

+### Default SSH port
+
+Set `ssh.default_port` in the config to use a non-standard port without specifying it every time:
+
+```sh
+netssh my-router        # → ssh -p 2222 -l admin 10.0.0.1

+
+```sh
+netssh -p 22 my-router  # -p flag wins → ssh -p 22 10.0.0.1
+```
+
+### Host shortcuts
+
+Configure short aliases so you can type `web01` instead of `web01.example.com`:
+
+```yaml
+shortcuts:
+  domains:
+    - .example.com
+    - .example.de
+  strip_hyphens: false  # optional
+```
+
+Resolution order:
+
+1. **Exact match** — the input is looked up as-is in the cache.
+2. **Domain expansion** — if the input contains no dot, each configured domain is appended and tried (`web01` → `web01.example.com`). If no cache hit, NetBox is queried with the expanded name.
+3. **Hyphen folding** (`strip_hyphens: true`) — hyphens are inserted back before looking up in the cache (`fsn1web01` → `fsn1-web01.example.com`). This only works when the host is already cached; run `netssh cache refresh` first.
+
+| Input | Config | Resolved as |
+|-------|--------|-------------|
+| `web01` | `domains: [.example.com]` | `web01.example.com` |
+| `fsn1web01` | `domains: [.example.com]`, `strip_hyphens: true` | `fsn1-web01.example.com` (cache only) |
+
+### Shell aliases
+
+Generate shell aliases for all cached hosts based on the shortcut settings:
+
+```sh
+netssh alias                  # bash/zsh syntax
+netssh alias --shell fish     # fish syntax
+```
+
+Example output:
+
+```bash
+# netssh aliases (3 hosts) — source with: eval "$(netssh alias)"
+alias db01='netssh db01.example.com'
+alias fsn1web01='netssh fsn1-web01.example.com'
+alias web01='netssh web01.example.com'
+```
+
+Add to your shell startup file:
+
+```sh
+# bash / zsh — in ~/.bashrc or ~/.zshrc
+eval "$(netssh alias)"
+
+# fish — in ~/.config/fish/config.fish
+netssh alias --shell fish | source
+
+# scripts
+source <(netssh alias)
+```
+
+Without a `shortcuts` config, the alias name is derived from the full hostname with dots replaced by underscores (e.g. `web01_example_com`). If two hosts would produce the same alias name, the first entry wins and a warning is printed to stderr.

+The TUI opens with your 10 most-recently-connected hosts. Start typing to search all cached hosts or query NetBox live.

 | Key | Action |

+**Tag and kind filter** — press `Ctrl+F` to open a second input line:
+
+```
+Filter: tag:prod kind:vm

+
+Multiple `tag:` values are AND-combined. The filter is applied locally against the cache; when doing a live NetBox search the first tag is also forwarded as a query parameter.

 ### Cache management
 
 ```sh
-netssh cache list            # show all cached entries
+netssh cache list                         # show all cached entries
-netssh cache refresh         # re-fetch all hosts from NetBox

-netssh cache clear           # wipe the cache
+netssh cache refresh --tag prod           # only hosts with the "prod" tag
+netssh cache refresh --kind vm            # only virtual machines
+netssh cache refresh --tag prod --kind vm # combine filters
+netssh cache clear                        # wipe the cache
 ```
 
+The cache is refreshed automatically in the background every 24 hours. The trigger fires on the next SSH connect or TUI start after the interval has elapsed — there is no delay to the connection itself. The timestamp of the last refresh is stored in `~/.cache/netssh/last_refresh`.
+
+To also trigger the check at shell startup (before you run any SSH command), install the shell hook:
+
+```sh
+netssh hook install             # auto-detects $SHELL
+netssh hook install --shell bash
+netssh hook install --shell zsh
+netssh hook install --shell fish
+```
+
+This appends a single line (`netssh shell-init`) to your shell profile. To remove it:
+
+```sh
+netssh hook uninstall
+```
+
+The hook is a no-op when the cache is fresh — it adds no measurable delay to your shell startup.

 Completions are served from the local cache — no network request on every `<Tab>`.
 
+## Shell Hook
+
+The shell hook runs `netssh shell-init` at the start of every new shell session. It checks whether the cache is older than 24 hours and, if so, starts a background refresh. The check reads a single small file and adds no measurable delay to your shell startup.
+
+### Install
+
+```sh
+netssh hook install             # auto-detects $SHELL
+netssh hook install --shell bash
+netssh hook install --shell zsh
+netssh hook install --shell fish
+```
+
+This appends exactly one line to your shell profile:
+
+```sh
+netssh shell-init  # netssh cache auto-refresh
+```
+
+| Shell | Profile file |
+|-------|-------------|
+| bash  | `~/.bashrc` |
+| zsh   | `~/.zshrc` |
+| fish  | `~/.config/fish/config.fish` |
+
+The install is idempotent — running it again does nothing if the hook is already present.
+
+Reload your profile after installation:
+
+```sh
+source ~/.bashrc    # bash
+source ~/.zshrc     # zsh
+source ~/.config/fish/config.fish  # fish
+```
+
+### Uninstall
+
+```sh
+netssh hook uninstall             # auto-detects $SHELL
+netssh hook uninstall --shell zsh
+```
+
+Removes the `netssh shell-init` line from the profile and collapses any blank lines left behind.
+
+### How it differs from the connect-time trigger
+
+| Trigger | When it fires |
+|---------|--------------|
+| Connect / TUI start | On the next SSH command or `netssh` TUI after 24 h |
+| Shell hook | On the first new shell session after 24 h |
+
+Both triggers are non-blocking: the refresh runs in the background and your SSH connection (or prompt) is not delayed. You can install both — they share the same `~/.cache/netssh/last_refresh` timestamp, so the background process runs at most once per 24 hours regardless of how many shells or connections you open.

+## Disclaimer
+
+This is a **vibe-coded** project: the entire codebase — architecture, implementation, tests, and docs — was generated by an AI assistant (Claude by Anthropic). No human has reviewed or audited the code. It works for the author's personal use case, but correctness and security are not guaranteed. Read the source before running it in sensitive environments.
 
 ## How it works
 
 1. `netssh` checks whether the first argument is a known subcommand (`configure`, `search`, `cache`, `completion`). If not, it enters SSH wrapper mode.
 2. On first run or when `netbox.url` is empty, the interactive setup wizard starts automatically.
 3. It parses the SSH arguments to extract the destination hostname, handling all flags that consume an extra argument (`-p`, `-i`, `-J`, …).
-4. It checks the local cache. If the entry exists and is within the TTL, it connects immediately.
+4. It resolves the destination: first an exact cache lookup, then shortcut expansion (domain append, hyphen folding) against the cache, and finally a fresh NetBox query with the expanded name. If the cache entry is within the TTL, no network request is made.
 5. Otherwise it queries NetBox (`/api/dcim/devices/` and `/api/virtualization/virtual-machines/` in parallel), runs the result through the resolver chain, and caches the IP.
 6. It calls `syscall.Exec` to replace itself with `ssh`, substituting the hostname with the resolved IP.
