3 mode config atuin history
```toml
[core]
# 0 = off, 1 = atuin history only, 2 = atuin history + default history
atuin-history = 0
```
Default is Mode 0 (turn off), who uses atuin history has to config it
manually
Mode 1 = atuin only (as you can see only 11 commands):

/>
Mode 2 = combine shell history + atuin history (prefer atuin):

/>
Mode 0 = turn off atuin
---
Custom atuin db path if anyone's using their own path (leave empty to
use default from atuin)
```toml
atuin-db-path = ""
```

I also handled the search menu overlay of Atuin, IRIS won't show in this
mode, but you have to change the keybind between 2 tool cuz they're
using same keybind Ctrl + R, but I think using IRIS make it unnecessary
to use Atuin search mode (82b180c9610f75d41008a54dfde474c7f2cce015)

## Feat
* feat(ai): add AI suggestion engine, context gathering, and ghost text
overlay (`v0.3.0`)
## Security & Perf
* fix(ai): restrict background `--help` execution to a hardcoded command
allowlist to prevent RCE
* fix(root): defer context cancellation in goroutine to prevent resource
leaks
* perf(ai): implement LRU eviction and maximum size limit for
`ProviderCache`
* perf(ai): truncate command context output
(`CommandContextProvider.Gather`) to 1000 characters to save tokens
## Bug Fixes
* fix(ai): add mutex synchronization and thread-safe snapshotting to
`AIEngine.RegisterProvider` and `GatherDynamicContext`
* fix(ai): return a copy of fresh `Suggestion` in `AIEngine.Suggest` to
prevent cache mutation
* fix(ai): use length-prefixed encoding in `EnvSnapshot.Hash` to prevent
delimiter collisions
* fix(ai): skip variable assignment lines containing `=` when extracting
Makefile targets
* fix(runner): check `scanner.Err()` and return `nil` on scan errors in
justfile generator
* test(ci): rename `git commit` to `git checkout` in overlay test to
resolve CI `typos` false positive
- I wrote a scripts to copy and generate all commands missing in iris
from fig repo: https://github.com/withfig/autocomplete
- Add a new script to generate commands docs about which commands
currently are inside commands folder
