Repeated formatting of cmd --% raw | text & stuff inserts another space before | on every pass. The parser includes trailing whitespace in the verbatim argument token, causing PSUseConsistentWhitespace to misidentify a missing separator.

• Boundary handling: Skip pre-pipe spacing corrections immediately after a --% verbatim argument. Continue formatting whitespace after that pipe and around other pipes.
• Regression coverage: Check repeated formatting with zero, multiple, and tab spacing, plus empty verbatim arguments and redundant-whitespace mode.

# Remains unchanged across formatting passes:
cmd --% raw | text & stuff

• Fixes Invoke-Formatter is not idempotent on --% verbatim arguments #2209

What changed in this PR

Addresses #2209 by preventing Invoke-Formatter from repeatedly inserting spaces before pipes following --% verbatim arguments.

Changes:

• Skip pre-pipe whitespace corrections after verbatim arguments while preserving formatting after the pipe and around other pipes.
• Add repeated-formatting regression tests for zero, multiple, and tab spacing, plus empty verbatim arguments.
• Verify redundant-whitespace mode preserves verbatim whitespace while correcting spacing after the pipe.
