chore: update insert licenser pe-commit-hooks to use current year

[Pouyanpi]

Update license headers to use year ranges

What

• Updated .pre-commit-config.yaml to add --use-current-year flag to the insert-license hook
• Ran pre-commit hook to update all Python file headers from 2023 to 2023-2025

Why

• Ensures copyright year stays current automatically
• Prevents duplicate license headers when files are modified
• Simplifies maintenance - hook will auto-update to 2023-2026 next year, etc.

Technical Details

Using the --use-current-year flag from Lucas-C/pre-commit-hooks, which:

• Updates existing headers to year ranges (e.g., 2023 → 2023-2025)
• Automatically extends ranges on file modification (e.g., 2023-2025 → 2023-2026 in 2026)
• Maintains consistency across the codebase

Thanks for bringing us up to 2025, looks good.

Will the pre-commit Insert license in comments update this automatically for all source files? If not maybe a find + sed would do the same thing

Yes, after looking at the pre-commit-hooks repo I found how I should approach this (have updated the PR description). It will update the license date without any conflict on uncommitted changes.
