feat: switch to /usr layout and add dynamic dependency detection

- Move binaries to /usr/bin and /usr/libexec for system integration - Add find-deps.sh script to detect required system packages from .so files - Update Makefile to generate Depends field dynamically using apt-file - Add list-deps target to Makefile for dependency analysis - Update README with new usage, features, and instructions - Update CI workflow to install apt-file and update its database

-# Zed Editor Packager
+# Zed Packager

-Automated packaging system for [Zed Editor](https://zed.dev/) for Debian/Ubuntu.
-
-## Description
-
-This project automatically creates `.deb` packages of Zed Editor from official GitHub releases and publishes them to a Gitea repository.
+A Makefile-based tool to package Zed editor as a Debian/Ubuntu package with dynamic dependency detection.

 ## Features

- **Automatic version detection**: Fetches the latest stable version from GitHub
- **DEB package building**: Creates a ready-to-install Debian package
- **CI/CD with Gitea Actions**: Automated workflow that:
-  - Checks daily for new versions
-  - Builds the package only if a new version is available
-  - Creates a Gitea release with the package
-  - Publishes the package to the Gitea Debian repository
+- **Automatic downloads** latest Zed release from GitHub
+- **Dynamic dependency detection** using `apt-file` to find required system packages
+- **System libraries** instead of bundled libraries for better integration
+- **Proper installation** with maintainer scripts for icon cache updates

-## Local Usage
-
-### Prerequisites
+## Prerequisites

 ```bash
-sudo apt-get install wget curl jq dpkg-dev
+sudo apt install wget jq dpkg-dev apt-file
+sudo apt-file update
 ```

-### Manual Building
+## Usage
+
+### Build the package

 ```bash
-# Build the package
 make
+```

-# Or step by step
-make download   # Download the archive
-make extract    # Extract the archive
-make deb        # Create the .deb package
+This will:
+1. Download the latest Zed release
+2. Extract the archive
+3. Analyze bundled libraries to detect system dependencies
+4. Create a `.deb` package with dynamic dependencies

-# Clean up
+### List dependencies
+
+To see what system packages are needed:
+
+```bash
+make list-deps
+```
+
+This will show a detailed analysis of each `.so` library and its corresponding Debian/Ubuntu package.
+
+### Install the package
+
+```bash
+sudo dpkg -i build/zed-editor_*.deb
+sudo apt-get install -f  # Install missing dependencies if any
+```
+
+### Clean up
+
+```bash
 make clean
 ```

-### Installation
+## How it works
+
+### Dynamic Dependency Detection
+
+The `find-deps.sh` script analyzes the `.so` files bundled with Zed and uses `apt-file` to find the corresponding Debian/Ubuntu packages. This ensures dependencies are always up-to-date.
+
+**Script usage:**

 ```bash
-# Install the locally created package
-sudo dpkg -i build/zed-editor_*.deb
+# Human-readable output
+./find-deps.sh /path/to/zed.app/lib
+
+# Machine-readable formats
+./find-deps.sh --format makefile /path/to/zed.app/lib  # Comma-separated
+./find-deps.sh --format list /path/to/zed.app/lib      # One per line
+
+# Quiet mode (no progress messages)
+./find-deps.sh --quiet --format makefile /path/to/zed.app/lib
 ```

-## Gitea Workflow
+### Makefile Integration

-The [`.gitea/workflows/build-and-release.yml`](.gitea/workflows/build-and-release.yml) workflow runs:
+The Makefile automatically calls `find-deps.sh` during package creation to generate the `Depends:` field in the control file. This means:

- **Automatically**: Every day at 2 AM (cron)
- **Manually**: Via the Gitea interface (workflow_dispatch)
- **On push**: On every push to the `main` branch
+- ✅ Dependencies are always detected from actual bundled libraries
+- ✅ Works with any Zed version
+- ✅ No manual maintenance required

-### Required Configuration
-
-To publish to the Gitea Debian repository, create a `PACKAGE_PUB_TOKEN` secret:
-
-1. Generate a personal access token on Gitea with package permissions
-2. Add it as a secret in the repository settings: `PACKAGE_PUB_TOKEN`
-
-### Workflow Behavior
-
-1. **Version check**: Compares the latest GitHub version with the latest Gitea release
-2. **Early exit**: If versions match, the workflow stops immediately
-3. **Build**: If a new version is detected, builds the .deb package
-4. **Publishing**:
-   - Creates a Gitea release with the version tag
-   - Uploads the .deb file to the release assets
-   - Publishes the package to the Gitea Debian repository
-
