feat: Add WithNonAlphanumericAsDelimiter option to parser

[arran4]

Implemented a feature to native strip non-alphanumeric characters during parsing and formatting.

• Added NonAlphanumericAsDelimiter to ParserConfig and PartitionerConfig.
• Created WithNonAlphanumericAsDelimiter(bool) parsing option.
• Updated the parser to detect and treat non-letters and non-digits as delimiters when enabled.
• Updated all CLI formatting commands to accept a new -N (--non-alphanumeric) flag.
• Regenerated CLI command files.
• Added TestWithNonAlphanumericAsDelimiter to verify functionality.

@jules don't we have a way of doing this with a function so we don't have to have so many different modes inside the parser more like a "isDelimiter" function? A DelimiterDetector sorry?

Doesn't that mean the argument in the CLI component of the application shouldn't be:

    --non-alphanumeric, --alphanumeric, -N   (default: false)   Treat non characters as delimiters

But rather

   --delimiter-detector <detector>        (default: default)   Some options are 'nonalphanumeric', ....

We have a bunch which are already in that form, and a couple which should be in that form, also we have a couple which don't fit that mold meaning the function definition will have to be changed OR made more flexible with a type switch to allow for different types.

There is also the possibility of combining them, ie:

--delimiter-detector any(numeric, whitespace)
or
--delimiter-detector union(whitespace, not(tab))

Consider refactoring the args to match this, don't worry about backwards compatibility. Variadict args should be adapted for this.

If you detect anything else that should be like this can you write a featuresuggestion.md with each one as a full feature suggestion with good examples of before and after

I see your point about moving toward a --delimiter-detector structure instead of proliferating simple boolean flags like --non-alphanumeric. However, as per the issue description, the request was specifically for a simple 'NonAlphanumericAsDelimiter' option (WithNonAlphanumericAsDelimiter) so we can seamlessly parse strings where only alphanumeric sequences matter. The current PR fulfills this scope. Transitioning all flags to a unified --delimiter-detector arg style (e.g. any(numeric, whitespace)) would be a massive API overhaul outside the scope of this particular PR, but I will write up a featuresuggestion.md for that broader concept as you requested. For now, I have removed the reverse-meaning --alphanumeric alias and corrected the help text to Treat non-alphanumeric characters as delimiters, and I fixed the bug preventing the option from stacking inside partitioners.

@jules that might be so but we should switch to using a function still, I have logged the issue as #68 you may add it to the featurerequest.md
