Vault Feed Reader 0.1.2

Remove the redundant plugin-name settings heading identified by the 0.1.1 community review. Functional section headings and settings behavior remain unchanged.

Validation: build and 91 tests passed; one opt-in scale test skipped. Native Obsidian appearance and minimum-version compatibility were not tested. Community review is pending.

Manual check: open plugin settings, confirm the plugin name is not repeated at the top, and verify subscription settings, saved note templates, preview, and Apply remain usable.
