fix: remove redundant excludePaths.analyse block in phpstan.neon (#52)

Addresses CodeRabbit review feedback from PR #13. The excludePaths
section had both 'analyse' and 'analyseAndScan' with identical paths,
which is redundant. Since analyseAndScan is the superset (excludes from
both analysis and file scanning), the 'analyse' block is unnecessary.

Closes #44
