   # Which issue does this PR close?
   
   <!--
   We generally require a GitHub issue to be filed for all bug fixes and 
enhancements and this helps us generate change logs for our releases. You can 
link an issue to this PR using the GitHub syntax.

   - Closes #NNN.
   
   # Rationale for this change
   
   <!--
   Why are you proposing this change? If this is already explained clearly in 
the issue then this section is not needed.
   Explaining clearly why changes are proposed helps reviewers understand your 
changes and offer better suggestions for fixes.
   -->
   The `Parser::parse` implementations for numeric types did not trim 
whitespace before parsing. This caused values like " 42 " or " 1.5 "  to fail 
parsing and return `None`, even though they represent valid numbers.
   
   
   
   # What changes are included in this PR?
   
   <!--
   There is no need to duplicate the description in the issue here but it is 
sometimes worth providing a summary of the individual changes in this PR.
   -->
   - Added `.trim()` calls before parsing in FloatType Parser implementations.
   - Added `string.trim()` at the top of the parser_primitive! macro, which 
covers all integer and duration types.
   
   
   # Are these changes tested?
   
   <!--
   We typically require tests for all PRs in order to:
   1. Prevent the code from being accidentally broken by subsequent changes
   2. Serve as another way to document the expected behavior of the code
   
   If tests are not included in your PR, please explain why (for example, are 
they covered by existing tests)?
   -->
   Yes. Added test_parse_trimmed_whitespace covering:
   
   - Float types with leading/trailing spaces and tabs/newlines
   - Signed and unsigned integer types with whitespace
   - Negative integers with whitespace
   - Whitespace-only strings returning None
   
   
   
   # Are there any user-facing changes?
   
   <!--
   If there are user-facing changes then we may require documentation to be 
updated before approving the PR.
   
   If there are any breaking changes to public APIs, please call them out.
   -->
   Yes. Numeric parsing now accepts strings with leading/trailing whitespace. 
This is a relaxation of the previous behaviour (previously `None`, now 
`Some(value)`), so it is not a breaking change.
