refactor: share file-level scope analysis across rules

[elecmonkey]

Motivation

Reuse the CachedByFile API previously introduced for the Rstest rule set to avoid constructing equivalent scope graphs multiple times for the same file.

Changes

Centralize reusable scope queries in scopeanalysis and migrate scope consumers to the shared file-level cache. Exact option shapes remain isolated, while complete reference graphs and declaration trees can be safely reused.

Move no-shadow analysis to the end of the file so it can reuse a graph initialized by an earlier rule.
