Current evaluation

Meson-built Python/GJS apps retain invalid build-time shebangs and fail to launch; a reproducer is linked, but the unlabelled issue has no maintainer triage or fix.

Suggested action: needs triage

Reason: The current MesonPlugin only runs Meson, Ninja, and DESTDIR install, with no shebang-rewrite step, so the reported failure is consistent with the code and the linked Graphs reproducer. However, #561 has no labels, assignee, or maintainer response—the sole comment is an automated Jira notice—and it does not define the expected Python/GJS replacement paths, so maintainers must scope and prioritize it.

Issue body

### Bug Description Same as the python plugin, when the meson plugin installs the files of a python or gjs based app, it cannot find the proper interpreter for them. To fix it, we have to manually fix the first line of those files. ### To Reproduce https://github.com/Sjoerd1993/Graphs/blob/main/snap/snapcraft.yaml#L88 This is an example snap, just remove this line and see the error. ### part yaml ```shell graphs: after: [ blueprint-compiler, numpy ] plugin: meson source: https://github.com/Sjoerd1993/Graphs.git meson-parameters: - --prefix=/snap/graphs/current/usr - --buildtype=release build-environment: - PYTHONPATH: $CRAFT_STAGE/usr/lib/python3/dist-packages:$PYTHONPATH - GI_TYPELIB_PATH: /snap/gnome-42-2204-sdk/current/usr/lib/$CRAFT_ARCH_TRIPLET/girepository-1.0:/snap/gnome-42-2204-sdk/current/usr/lib/girepository-1.0 organize: snap/graphs/current/usr: usr parse-info: [usr/share/appdata/se.sjoerd.Graphs.appdata.xml] ``` ### Relevant log output ```shell Logs can be found by installing the snap that'll build from the above given yaml. It'll fail to find the correct python interpreter. ```

2026-10-02 02:03 AM UTC	qwen/qwen3.8-27b	Impact: 45 Quick Win: 15 Complexity: 45 Confidence: 75 Actionability: 60	needs triage	Meson plugin does not rewrite shebangs of Python/GJS scripts it installs, so built snaps fail to find the interpreter; reporter gives a Graphs snap reproducer. No labels or maintainer response; code confirms meson plugin has no shebang handling.

Unlabeled, no maintainer response, and the code still lacks shebang handling.
