- remove unused packages from home-manager configurations (luarocks, bun, prettier, eslint, skim, overmind)

- comment out some optional packages in editor and frontend-dev configurations

- fix starship custom module name from git_town to gittown and format string

Change git merge autostash setting from true to false in home-manager configuration. This aligns with the current workflow preferences where automatic stashing during merge operations is not desired.

Move git-town related configuration from git.nix to a dedicated git-town.nix module

Add conditional enabling of git-town features in lazygit and starship configurations

Introduce new git-town enable option in config.nix

add jj-ai-commit.sh script for multi-line commit message handling

add jj-commit-context.sh script to provide commit context for AI generation

update jj.nix configuration with new ai-ci command that combines both scripts

The jj-ai-commit.sh script allows for multi-line commit message input and properly formats it for jj describe command. The jj-commit-context.sh script provides structured context including staged changes and recent commit history. The new ai-ci command in jj.nix combines these scripts with aichat to generate and apply commit messages automatically.

- Remove --quiet flag from jj describe command in jj-ai-commit.sh

- Enhance jj.nix script to handle interactive commits when no revision is provided

- Add fallback to extract parent commit ID from jj status output

- Rename new-from-bookmark alias to nb for brevity

- Improve error handling and user feedback in commit process
