Dear Maintainer,

In Ubuntu stonking (and environments with Qt 6.11 / LTO / _FORTIFY_SOURCE=3),
the test suite crashes with a segmentation fault in SECTION("search")
at src/tests/filetests.cpp:786:

  actions
    search
  ../src/tests/filetests.cpp:786: FAILED:
  due to a fatal error condition:
    SIGSEGV - Segmentation violation signal
  1/1 editor:tests FAIL killed by signal 11 SIGSEGV

This happens because File instances are allocated with new and leaked in
the test cases. Leaked instances remain registered in the Qt event loop,
and when their terminal is destroyed, incoming events (such as
cursorPositionChanged) trigger a use-after-free SIGSEGV.

Upstream resolved this in commit 294293edbaf9ba03f169c25e88005dca5f9b79e5
("tests: filetests: Use unique_ptr to avoid File leaks.") by managing
File instances with std::unique_ptr.

The attached patch backports this fix to 0.1.81-1. With this patch applied,
all 12 test cases pass without errors.

Dear Maintainer,

Further analysis showed that upstream commit 294293edbaf9ba03f169c25e88005dca5f9b79e5 alone
is not sufficient when the full test suite runs sequentially.

Instances of File were also leaked in readWrite() (src/tests/tests.cpp) and in
src/tests/attributes.cpp. These leaked instances remain active in the Qt event loop,
and when their terminal is destroyed, subsequent event loop iterations in later tests
trigger a use-after-free SIGSEGV in termpaint_text_measurement_feed_codepoint.

Upstream subsequently resolved these leaks as well:
- 294293edbaf9ba03f169c25e88005dca5f9b79e5 ("tests: filetests: Use unique_ptr to avoid File leaks.")
- 9657fd3ad95536c19c8b3f68987614d81b04845c ("tests: readWrite: Fix memory leak.")
- bbfd527dd697b4ffe57894c8f66da5cd18c50e91 ("tests: cleanAttributesFileName: Fix memory leak.")
- fbeb86f82fe942464944afacbdd314a11faf5bfe ("tests: attributes: Fix memory leak.")

The attached patch combines all four upstream fixes. With this patch applied,
all 17 test cases pass (2482 assertions, 0 failures) on both build-edit and build-tiny.
