chore: release 1.0.5

[nilsandrey]

Motivation

• Ensure the published plugin version and compatibility metadata are incremented because the previous PR forgot to bump the patch version.
• Record the release notes for the manifest author metadata change so the changelog reflects the published release.

Description

• Bump the patch version from 1.0.4 to 1.0.5 in manifest.json and package.json.
• Add a 1.0.5 entry to versions.json mapping to 0.15.0.
• Prepend a 1.0.5 release section to CHANGELOG.md referencing PR Fill manifest author fields #16.

Testing

• Ran npm test which executes vitest run and the test suite completed successfully.
• Test summary: 1 test file executed with 135 tests passed (135/135).
