Invalid buildinfo.ignore/skipModules globs crash build with PatternSyntaxException

User-supplied glob patterns are compiled at runtime without validation and can abort the whole build with a confusing exception:

- `BuildInfoWriter.setIgnore(List)` (line 350): `fs.getPathMatcher("glob:" + i)`
- `AbstractBuildinfoMojo.isSkipModule()` (line 436): `fs.getPathMatcher("glob:" + i)`

For example `buildinfo.ignore` set to an invalid glob (unbalanced `[` or trailing `\`) throws `PatternSyntaxException` (an `IllegalArgumentException`) mid-build, instead of producing a clean error explaining the bad pattern.

Suggested fix: validate all globs during mojo initialization and report a precise error naming the offending pattern.

Start by reading BuildInfoWriter.setIgnore(List) and AbstractBuildinfoMojo.isSkipModule(), then trace mojo initialization to find where both glob sources are processed. Done means invalid patterns produce a clean error that names the offending pattern instead of aborting the build with PatternSyntaxException.
