cuspatial: stop development and package publishing

[jameslamb]

Description

RAPIDS 25.04 was the final release to include cuspatial packages:

• https://docs.rapids.ai/notices/rsn0045/
• https://anaconda.org/rapidsai/cuspatial
• https://pypi.org/project/cuspatial-cu12/#history

This issue tracks the work of removing cuspatial references across RAPIDS from the 25.06 release forward.

Benefits of this work

• reduces maintenance burden and complexity
• clarifies the development status of cuspatial

Acceptance Criteria

• no remaining unnecessary references to cuspatial across RAPIDS projects

Approach

Look for references to cuspatial and cuproj: (GitHub search)

• publish an RSN saying cuspatial is deprecated (Stop publishing cuspatial packages - v25.06 docs#588)
• stop publishing nightlies
  • docs (Disable cuSpatial nightly packages and docs. docs#600)
  • workflows (Drop cuSpatial from nightly builds/tests. workflows#85)
• remove entries in rapids-metadata (Add 25.08 rapids-metadata#53)
• update RSN to "completed" (RSN 45: move to completed docs#645, chore: update status field for two completed RSNs docs#626)
• remove cuproj and cuspatial from rapids meta-package
  • 25.06 (Remove cuspatial and cuproj from rapids metapackage. integration#757)
  • 25.08 (remove cuspatial and cuproj from rapids metapackage integration#781)
• remove from devcontainers (Remove cuSpatial from devcontainers devcontainers#509)
• remove from user-facing docker images
  • notebooks (Remove cuSpatial notebooks docker#742)
  • all other references (remove more cuspatial references docker#774)
• deployment
  • references in docs (remove cuspatial references in docs deployment#587)
  • uses in code (Remove uses of cuspatial deployment#586)
• pypi-wheel-scripts (https://github.com/rapidsai/pypi-wheel-scripts/pull/35)
• release-scripts (https://github.com/rapidsai/release-scripts/pull/33)
• other miscellaneous references in comments, docs, etc.
  • cucim (remove cuspatial references cucim#906)
  • cudf (remove cuspatial references, avoid triggering tests on clang-format config changes cudf#19380)
  • raft (remove cuspatial references, avoid triggering tests on clang-format config changes raft#2740)
  • rapidsmpf (remove cuspatial references, reduce unnecessary CI runs rapidsmpf#379)
• remove / mark broken 25.08 cuproj and cuspatial packages (https://github.com/rapidsai/ops/issues/4106)
• archive the repo
  • add a note to the README (add note about the repo being archived [skip ci] cuspatial#1574)
  • actually move it to Public Archive (https://github.com/rapidsai/ops/issues/4120)
• continue hosting cuspatial and cuproj docs but move them under and "inactive" or similar section (https://github.com/rapidsai/ops/issues/4044)
• Update rapids.ai website references to cuSpatial (https://rapids.ai/ecosystem/) (Remove cuSpatial references rapids.ai#452)
