## Motivation and Context
Now that we're in 2026, we need to update the license headers on all the
files. Unfortunately, Hawkeye doesn't have an attribute for the current
year to help us avoid this in the future. Instead, I had to work around
this by doing the following:
1. Update licenserc.toml with:
```
[properties]
... (other properties)
currentYear = "2026"
```
2. Update scripts/license-header.txt with
```
Copyright ©{{ " " }}{%- set created = attrs.git_file_created_year or
attrs.disk_file_created_year -%}{%- set modified = props["currentYear"]
-%}{%- if created != modified -%} {{created}}-{{modified}}{%- else
-%}{{created}}{%- endif -%}{{ " " }}{{ props["copyrightOwner"] }}.
```
Then I removed these two changes before committing. After this PR is
merged, all files will have recently had git updates, so the existing
code for setting the modified year should work as intended.
