release: v13.10.1 (#856)

## Summary

Documentation maintenance release. **No functional code changes** since
v13.10.0 — the CI/template-adoption and dev-dependency work in this
window (`.github/`, `Build/`, `Tests/`) is `export-ignore`d and does not
ship to TER/Packagist.

## Shipped changes (since v13.10.0)

- **Corrected template-override TypoScript examples** (#845) — the
documented override mechanism was broken: `settings.*RootPaths` placed
as siblings of `preUserFunc` never reach
`ImageRenderingService::buildTemplatePaths()` (`stdWrap_preUserFunc`
only forwards `$conf['preUserFunc.']`). `setup.typoscript` +
`Documentation/Examples/Template-Overrides.rst` now show the correct
nested structure, including the
`externalBlocks.figure.stdWrap.preUserFunc` variant for captioned
images.
- **README restructured** (#842) — narrative/SEO/GitHub-UX, plus the
TYPO3 version-compatibility branch matrix.

## Release mechanics

- `ext_emconf.php`: `13.10.0` → `13.10.1` (composer.json has no version
field — derived from tag)
- CHANGELOG `[13.10.1]` section added
- Tag `v13.10.1` to be pushed from `main` HEAD after merge → CI
publishes

## Type of Change

+- **Corrected template-override TypoScript examples** ([#845](https://github.com/netresearch/t3x-rte_ckeditor_image/pull/845)) — the documented override mechanism was broken: `settings.templateRootPaths`/`partialRootPaths`/`layoutRootPaths` placed as siblings of `preUserFunc` never reach `ImageRenderingService::buildTemplatePaths()`, because `stdWrap_preUserFunc` only forwards `$conf['preUserFunc.']` to the callable. The `Configuration/TypoScript/ImageRendering/setup.typoscript` comments and `Documentation/Examples/Template-Overrides.rst` now show the correct nested structure, plus the matching `lib.parseFunc_RTE.externalBlocks.figure.stdWrap.preUserFunc` block required for captioned (figure-wrapped) images.
+- **README restructured** ([#842](https://github.com/netresearch/t3x-rte_ckeditor_image/pull/842)) — narrative, SEO, and GitHub-UX conventions, plus a documented TYPO3 version-compatibility branch matrix.
