Merge 8f80fc38c9 into 57286c3887

Replaces the previous contents of this branch, which added editor/OS and
shared-library rules that belong in Global/ per the contributing guidelines.

Two changes remain, both scoped to Julia.gitignore:

* `*.jl.*.mem` — `--track-allocation` writes `<file>.jl.<pid>.mem`, so the
  existing `*.jl.mem` rule never matches the files Julia actually produces.
  This mirrors the `--code-coverage` section, which already carries both
  `*.jl.cov` and `*.jl.*.cov`.

* `.CondaPkg/` — CondaPkg creates this directory inside the active project
  and populates it with a machine-specific Conda environment.
