#3406 chore: Rename internal packages used for end-to-end testing to avoid collisions with PyPI packages Pull request opened by edgarrmondragon ## Summary by Sourcery Rename internal Singer tap/target/mapper packages used for end-to-end testing to use a meltano- prefixed namespace and align code metadata with the new package names. Enhancements: • Update workspace and uv source configuration to reference the renamed meltano-* test packages instead of the previous unprefixed names. • Set explicit package_name attributes on test taps, targets, and mapper classes to match the new meltano-* distribution names. • Configure Hatch wheel build targets for each renamed package so their Python modules are correctly included in built artifacts. Chores: • Rename all internal end-to-end test package distributions and directories from mapper-_/tap-_/target-* to meltano-mapper-_/meltano-tap-_/meltano-target-* to avoid collisions with similarly named PyPI packages. meltano/sdk
