Add Directory Compression Support to ArchiveCompress

### Feature description

### Problem

`ArchiveCompress` currently only supports compressing individual files with explicit mapping. It **cannot compress directories recursively**, making it impractical for directories with 100+ files.

**Current:** ✅ Works with file maps only
```yaml
from:
file1.txt: "{{ outputs.task1.uri }}"
file2.txt: "{{ outputs.task2.uri }}"
```

**Needed:** ❌ Doesn't work with directories
```yaml
from: "kestra:///namespace/path/to/directory" # or local filesystem path
```

### Use Cases

- Archiving entire directories for backup
- Compressing large datasets with 100+ files
- Dynamic file sets where names/counts are unknown
- Compressing all outputs from previous workflow tasks

### Proposed Solution

Add `fromDirectory` property (or enhance `from` to auto-detect directories):

```yaml
tasks:
- id: archive_compress
type: io.kestra.plugin.compress.ArchiveCompress
fromDirectory: "kestra:///namespace/path/to/directory"
algorithm: ZIP
```

### Technical Requirements

1. Auto-detect if input is a directory vs file
2. Recursively walk directory structure
3. Preserve relative paths in archive
4. Support namespace storage URIs and local filesystem paths
5. Maintain backward compatibility with existing map-based usage

**Note:** `ArchiveDecompress` already handles directory structures correctly when extracting.
