* lazysql: fix version display in `lazysql version` command
Sets `main.version` using `ldflags` to ensure `lazysql version` shows the
correct version instead of "dev".
* lazysql: add passthru.tests.version
To address previous issues where lazygit incorrectly reported its version as
"dev," this commit introduces `passthru.tests.version` for lazysql. This test
verifies that the version command for lazysql (`lazysql version`) correctly
reports the expected version.
