docs(contributing): drop obsolete CMake and protoc prerequisites (#7693) ## Summary Closes #7535. The core development setup in `docs/contributing/development.md` still told every contributor to install CMake and `protoc`. Neither is required for the supported core-development workflow (a repo-wide search shows no build script or `Makefile` target invoking either tool), so this removes both steps and renumbers the remaining instructions. - Remaining sequence: `uv` → Rust → Node.js → clone → `make .venv` → `make hooks`. - No CMake/protoc prose remains that implies either is a universal prerequisite. - CMake guidance specific to the C++ extension example lives in `examples/hello_cpp/README.md` and is untouched. No build scripts, CI, or dependency provisioning changes. ## Validation - Re-read the rendered setup sequence end to end; numbering is contiguous and the flow is unchanged. - `grep -ri "cmake\|protoc" docs/` returns no prerequisite references outside this removed guidance.

docs: document custom source pushdowns Explain the Pushdowns object passed to get_tasks, how to inspect filters with ExpressionVisitor, and how projection and limit hints fit together. An in-memory source example backed by end-to-end tests shows pruning parts from an equality predicate.

chore: consolidate mypy configuration Run mypy over the package from pyproject.toml as a single source of truth and drop the redundant per-module ignore override. The pre-commit hook now runs mypy without passing filenames so the config governs what is checked.

feat(catalog): support nested namespaces in MemoryCatalog Namespace keys now hold full paths so namespaces may be nested to arbitrary depth, and dropping a namespace cascades to its descendants. Table and namespace identifiers retain the complete qualifier instead of joining the path into the table name.

docs(audio): align AudioFile and audio function docstrings with behavior - Document the required `soundfile`/`librosa` dependencies and the `daft[audio]` install path, including the `ImportError` cases. - `AudioFile.resample` returns a NumPy array, not an `AudioFile`; note that resampling is only well-defined for mono input. - `AudioFile.to_numpy` documents float64 output with `(frames,)` or `(frames, channels)` shapes. - `audio_metadata` documents the current expression schema, including `Float64` frames versus the `int` returned by `AudioFile.metadata()`. - Expression-level `resample` documents `Tensor[Float64]` and skips its network-backed doctest output. - Fix "a audio file" grammar and synchronize the audio guide wording.

feat(dashboard): auto-discover a locally started dashboard `daft dashboard start` now publishes its URL next to the PID file, and clients resolve it when `DAFT_DASHBOARD_URL` is not set. Running a script after starting the server is enough for queries to appear; no environment variable is required, and when no dashboard was started there is no extra work beyond a local file check. - The CLI writes `daft_dashboard.url` (honoring `DAFT_DASHBOARD_PID_DIR`) and removes it on stop and on graceful shutdown. - `DashboardSubscriber` and the distributed statistics subscriber resolve the URL through the same helper, so both paths see the discovered server. - The startup banner points at loopback (127.0.0.1) when listening on all interfaces, and explains the automatic connection instead of only printing the env var.

fix(logical-plan): expand wildcards inside struct constructors `to_struct(col("*"))` was duplicating the whole struct constructor once per matching column, producing several single-field struct columns (all named `struct`) instead of one struct containing every column. Expand wildcard arguments in place when the enclosing expression is a struct constructor, so the constructor sees individual fields. Wildcards outside a struct constructor keep their existing tree-duplication semantics.
