* feat(pregate): lanes follows Python imports and mock.patch targets The import graph only parsed JS/TS imports, so in a Python repo every touched module failed `lanes` with PREGATE_NO_LANE even though SOURCE_EXT, TEST_FILE_RE and the pytest runner/summary already understood Python. Python sources now contribute `import a.b`, `from a.b import c` (c may be a submodule), parenthesised multi-line lists and relative `from ..pkg import x` edges, resolved to `a/b.py` or `a/b/__init__.py` from the repository root. Package `__init__.py` files on the path get edges too, since Python executes them on import. Modules outside the repo resolve to nothing. In test files, dotted string literals such as `'pkg.mod.Class.method'` (mock.patch targets) resolve to the longest dotted prefix that is a repo module.

A generator that degrades and still exits 0 then looked stale, and the fix line sent people to rerun the generator. gstack-regen check and the pregate regen check now report "dependencies missing; run <install>" with its own result code and troubleshooting anchor; the install command follows the lockfile. The fixture reproduces the shape GSTA-31 saw in gbrain.

The spec is now dots followed by an optional word-led name. - Dotted literals and imports resolved every prefix with repeated split/join. Names are capped at 32 segments, deeper than any module path. - A literal that also named a repo file skipped its mock.patch reading; both readings now add edges. - A package and a same-named module both map (Python loads the package). - Imports after `;` or a compound statement's `:` are recognised.

The spec now starts with a dot or a word character. - Strings and comments are blanked by a single linear scanner that honours backslash escapes, so an escaped triple quote no longer ends a docstring early and swallows the imports after it. - The fixed 32-segment cap dropped real deep modules. Dotted names are now bounded by the repo's deepest path, which no module can exceed.
