build: bump version to 0.9.7

Use wlr_client_buffer->texture directly instead of wlr_texture_from_buffer.
All buffers in content_tree are wlr_client_buffer.

wlr_texture_from_buffer calls client_buffer_begin_data_ptr_access which
fails when client_buffer->source == NULL (client released buffer early,
e.g. wl_shm foot-terminal).

+[0.9.7-commits]
+
+This is a small bug fix release.
+
+```
+               0.9.6--------0.9.7  <--- v0.9 branch with bug-fixes only
+                /
+               /
+0.9.4--------0.9.5--------  <-- master (built with wlroots-0.20)
+```
+
+## Fixed
+
+- Fix intermittent failed-to-get-texture issue with some clients (e.g. foot)
+  when using the window-switcher in the thumbnail mode. [#3511] @yuiiio
+- Fix tablet tool tilt motion. [#3494] @jp7677
+- Handle window-switcher buffer allocation failure when in 'thumbnail' mode.
+  This is believed to be very unlikely to happen, but has been reported by one
+  user and is believed to be GPU driver related. [#3490] @Consolatis
+
+## 0.9.6 - 2026-03-15
+
+[0.9.6-commits]
+
+This is an earlier-than-usual release containing bug fixes only. It has been
+done on a separate branch (v0.9) to avoid the inclusion of refactoring and new
+features.

+0.9.4--------0.9.5--------  <-- master
+```
+
+### Fixed
+
+- Disable outputs where all modes fail [#3428] [#3429] @Consolatis @kode54
+- Fix regression in `0.9.4` that causes `NextWindow` action to segfault when
+  no outputs are connected. This fixes a window-switcher crash with some
+  Nvidia GPUs/drivers after suspend [#3425] [#3430] @Consolatis
+- Fix typo to allow `xdg-dialog-v1` global [#3426] @xi
+
+### Changed
+
+- Disallow X11 window always-on-top requests by default to fix an issue whereby
+  Alt+Tab cannot be used to switch to other windows when using some XWayland
+  Wine games [#3441]. Add window-rule property `allowAlwaysOnTop` to optionally
+  allow this always-on-top requests. Add the snippet below to the `rc.xml` file
+  to restore the previous behaviour. [#3445] @Consolatis
