Retire bundled Chinese localisation surface

[Wonderforge-Lab]

Purpose

Retire the bundled Simplified-Chinese/localisation surface from the distributed CapstanAI LabNote template after preserving it in Dev-for-LabNote.

This is a focused removal and route-repair PR. It does not include the planned humanising rewrite of the main README.

Preservation gate

Preservation completed before this cleanup branch was created:

• Chinese-written source snapshot
• Preservation addendum

Both PRs are merged. Their manifests preserve the removed files and the pre-cleanup versions of affected historical/upgrade documents against CapstanAI-LabNote commit e2df87b9b0c5cab987aa86ebe652649660dfc53d.

Removed

64 files:

• the complete locales/ tree;
• all six files under docs/localization/;
• locale freshness/invariant tests, regression coverage and review acknowledgements;
• three locale-specific archive/release notes, including the bilingual v0.3.1 note.

Repaired

Eight surviving files:

• README.md: removed the language selector and locale-validation claim;
• AI_ENTRYPOINT.md: removed locale routing and the localised-entrypoint authority reference;
• docs/README.md: removed the Chinese documentation route;
• docs/UPGRADING.md: removed locale-sync upgrade obligations;
• docs/PROJECT_EVOLUTION.md: retained truthful release history and recorded preservation/retirement;
• docs/PROJECT_PROVENANCE.md: retained historical contributor credit while removing active localisation policy;
• docs/registry/REGISTRY_SURFACE_AUDIT.md: made the former Chinese surface explicitly historical;
• .github/workflows/validate.yml: removed only the locale-specific checks and comparison-base routine.

The main README prose rewrite remains deliberately separate.

Whole-tree sweep

The proposed 170-file tree was scanned after publication to the branch.

• Chinese/Han characters: 0
• zh-CN: 0
• locales/ references: 0
• removed locale-check references: 0
• surviving Chinese-language references: 4, all English-only and confined to truthful historical records

Validation

GitHub Actions push validation: passed.

A disposable clone of this branch was then customised and given an ordinary Registry v1 packet, visit record and signoff. After regenerating compatibility views, it passed:

• python scripts/validate_repo.py --registry
• python tests/test_validator_smoke.py
• python scripts/generate_registry_views.py --check
• python tests/test_generated_views.py
• python tests/test_markdown_links.py
• python tests/test_bridge_config.py
• python tests/test_tag_promotion.py
• git diff --check

This confirms that normal README customisation and ordinary deposits no longer encounter locale-maintenance checks.

Separate finding

The disposable test confirmed that examples/minimal_routine_deposit/*.json still demonstrates pre-Registry-v1 fields. That existing example drift is not changed here because it is unrelated to localisation retirement; it should be repaired in a separate focused change.

Boundaries

• No Dev-for-LabNote file was changed during cleanup.
• No repository other than CapstanAI-LabNote was changed.
• No release, tag or historical commit was rewritten.
• This PR is not to be merged without human review.
