refactor(errors): implement structured error handling for improved debugging

Implement multihost functionality allowing separate management of common and host-specific dotfiles. Add new commands and flags for handling host-specific files, update core logic for file storage and tracking, and enhance documentation to reflect new capabilities.

+Your files live in `~/.config/lnk` (a Git repo). Common files go in the root, host-specific files go in `<host>.lnk/` subdirectories. Lnk creates symlinks back to original locations. Edit files normally, use Git normally.
+
+## Multihost Support
+
+Lnk supports both **common configurations** (shared across all machines) and **host-specific configurations** (unique per machine).
+
+### File Organization
+
+```
+~/.config/lnk/
+├── .lnk                    # Tracks common files
+├── .lnk.laptop             # Tracks laptop-specific files

+
+### Usage Patterns

+# Common config (shared everywhere)

 ## Commands
 
 - `lnk init [-r remote]` - Create repo
-- `lnk add <files>` - Move files to repo, create symlinks
-- `lnk rm <files>` - Move files back, remove symlinks
-- `lnk list` - List files managed by lnk
+- `lnk add [--host HOST] <files>` - Move files to repo, create symlinks
+- `lnk rm [--host HOST] <files>` - Move files back, remove symlinks
+- `lnk list [--host HOST] [--all]` - List files managed by lnk
 - `lnk status` - Git status + sync info
 - `lnk push [msg]` - Stage all, commit, push
-- `lnk pull` - Pull + restore missing symlinks
+- `lnk pull [--host HOST]` - Pull + restore missing symlinks
+
+### Command Options
+
+- `--host HOST` - Manage files for specific host (default: common configuration)
+- `--all` - Show all configurations (common + all hosts) when listing
+- `-r, --remote URL` - Clone from remote URL when initializing
 
 ## Technical bits
 
 - **Single binary** (~8MB, no deps)
 - **Relative symlinks** (portable)
 - **XDG compliant** (`~/.config/lnk`)
+- **Multihost support** (common + host-specific configs)
+- **Git-native** (standard Git repo, no special formats)

-## FAQ
-
-**Q: What if I already have dotfiles in Git?**  
-A: `git clone your-repo ~/.config/lnk && lnk add ~/.vimrc` (adopts existing files)
-
-**Q: How do I handle machine-specific configs?**  
-A: Git branches, or just don't manage machine-specific files with lnk
-
-**Q: Windows support?**  
-A: Symlinks work on Windows 10+, but untested
-
-**Q: Production ready?**  
-A: I use it daily. It won't break your files. API might change (pre-1.0).
