slop-audit: the brush-up pass, and the rename to slop_audit

slop-audit spent the rest of the week being made presentable rather than more capable. A brush-up design split the work into Phase 1 (docs and packaging) and Phase 2 (hygiene), and Phase 1 followed: an MIT license, a changelog and pyproject.toml metadata (e7bc0a3) with the README polished and GitHub publication marked done (9b6a418), merged as PR #1.

Phase 2 then renamed the import package text_audit → slop_audit so it matches the distribution name, and wired the live independent-agreement / corroborated findings into the report — restricted to the style, slop and prose tools, which is the side of the harness that has something to corroborate (07ccaaf, PR #2). The changelog notes the package was text_audit until Phase 2, because the rename is the one change the 0.1.0 entry could not describe.
