Add shared zone point resolution

[jscott3201]

Summary

• finalize a strict cxf-library/points/v2 contract with explicit imports and compatibility aliases while preserving strict v1 dictionaries
• move zone_temp, both active zone temperature setpoints, and occ_sensor to points/zone.points.json as their single canonical semantic owner
• resolve existing VAV and SYS bare names deterministically in Python lint, Rust fault verification, and generated book links
• preserve 15 dictionaries, 183 concrete records, four compatibility aliases, and every existing fault-card/CXF/vector name and content ID

Validation

• focused point resolver and semantic tests: 23 passed
• book point-link tests: 2 passed
• python3 tools/lint/point_semantics.py twice: 15 dictionaries and 13 bounded reviewed mappings
• full lint suite: 93 passed
• Rust tests: 11 passed
• all 137 fault directories and scenarios passed through the pinned Engine; generated routine verification remained clean at zero deployments
• dataset harness: 32 passed; tiny FPU replay assertions passed
• pinned G36 source inventory: 431 release and 693 development files
• SVG, registry, routine schema, routine semantic, and routine catalog lints passed
• book generation and mdbook build book passed

Boundaries

This does not add proposal-only zone points, move VAV airflow or equipment-owned records, centralize contextual rht_vlv_cmd bindings, change fault cards/CXF/vectors/runtime behavior, clean up derived aggregates or topology metadata, import production routine profiles, or modify Engine or Studio.

Cycle 1 consolidated review: PASS at b001aca4fa4a87c50eef89972b5531f289bedf39.

Both independent reviewers found no blocker or major defect. Exact-head verify and build checks completed successfully, and the PR head remained unchanged after review.

Deferred, non-blocking observation: the Python resolver validates the cross-family resolution contract rather than duplicating every namespace and point-semantic check; tools/lint/point_semantics.py and the Rust verifier retain those checks. No change requested.
