Fast Copy Strict Control

fast-copy strict control

With the new fast-copy strict control enabled, Terragrunt compiles each include_in_copy and exclude_from_copy pattern once and evaluates it inline during a single copy walk. This avoids re-walking subdirectories for every pattern, which should result in noticeable speed improvements for large source modules.

The new matcher does not collapse ** to zero path segments when a neighbor is a wildcard, so a/**/*.tf matches a/sub/main.tf but not a/main.tf. Patterns that relied on the old collapsing behavior should use brace alternation like {*.tf,**/*.tf} to cover both depths.
