re-adds the \\S requirement to the regex

[Copilot]

Pull request overview

Updates multiple built-in language configurations to refine the “continue line comment on Enter” rule, reintroducing a non-whitespace (\S) requirement so // alone won’t trigger comment continuation. This is aligned with the goal of reducing accidental comment continuation in common non-comment scenarios (e.g., URLs/paths) while still supporting intentional line comments.

Changes:

• Tightened beforeText for // continuation to require actual comment content (\S) and to better constrain where // is recognized as a comment start.
• Simplified afterText from ^(?!\s*$).+ to ^(?!\s*$) across affected language configurations.
• Adjusted C# rules to explicitly handle /// documentation comment continuation separately from normal // comments.

• The documentation-comment onEnter rule also matches lines starting with //// because it only checks for a /// prefix. That will cause Enter inside a normal //// line comment to continue with /// instead of // .

Consider excluding a 4th slash via a negative lookahead so only exactly-three-slash doc comments trigger this rule.
