Enclosing class:

public static class StringFunctions.PathToken
extends TypedFunction

#{pathToken(s)} — normalize a user-supplied path token for safe interpolation into a path= template.

Strips leading and trailing /, plus a trailing /* (or * that sits immediately after a /). Multi-segment paths are preserved.

Edge cases:

• "" → ""
• "/" → ""
• "/*" → ""
• "jsp" → "jsp"
• "/jsp" → "jsp"
• "/jsp/" → "jsp"
• "/jsp/*" → "jsp"
• "jsp/*" → "jsp"
• "/api/v1/*" → "api/v1"

Used in SVL-configurable mixin paths so users can supply "jsp", "/jsp", "/jsp/", "/jsp/*", or "jsp/*" and the template /#{pathToken(${juneau.jsp.path:jsp})}/* always resolves to a clean /jsp/*.
