feat(obsidian): add property frontmatter commands

- Expose Obsidian CLI property commands via the n8n Obsidian API node
- Add a new Property resource with operations: Set, Read, Remove, List
- Implement correct args mapping for property:set/property:read/property:remove/properties
- Return raw CLI stdout for property read/list for easier downstream parsing
- Update node README with frontmatter/property usage examples
- Bump package version to 0.2.5

+## Properties / frontmatter
+The official Obsidian CLI supports property/frontmatter commands. The n8n node exposes them as the **Property** resource:
+
+- **Set** sends `property:set path=<note> name=<property> value=<value> type=<type>`
+- **Read** sends `property:read path=<note> name=<property>`
+- **Remove** sends `property:remove path=<note> name=<property>`
+- **List** sends `properties name=<optional> format=<yaml|json|tsv>`
+
+Examples:
+```text
+path=00 Kontext/Feedback Browser CLI Tests.md
+name=tags
+value=kontext, feedback-browser-cli-tests
+type=list
+```
+
+```text
+path=00 Kontext/Feedback Browser CLI Tests.md
