### What problem does this PR solve?
External views currently resolve a table handle when loading the
statement snapshot, before their SQL is expanded. Skip that table-only
path for known views; their base tables retain normal snapshot pinning.
Reject unsupported view scan parameters such as `@branch` and `@tag`
instead of silently ignoring the requested selector.
### Release note
Avoid table metadata requests for external views during snapshot
binding, and reject unsupported view scan parameters.
