Fix formatting/lint issues in cross-SDK E2E test fixes

- rust/tests/e2e/hooks_extended.rs: apply nightly rustfmt (shortening the
  tool name to "view" lets the closure collapse onto one line).
- python: split the long todos PROMPT into implicit string concatenation
  to satisfy ruff E501 (line <= 100); string content is byte-identical.
- dotnet: keep the postToolUseFailure Skip reason on a single line to
  match the existing codebase convention and dotnet format.
