Incorrect value for filename when using --front-matter

[hernancerm]

Describe the bug

The value of filename in a query, for a command which has --front-matter, is substituted for the name of a temporary file instead of the correct file name. To reproduce this bug execute any command of the form:

yq --front-matter=<extract-or-process> 'filename' <filepath>

Version of yq: 4.49.2
Operating system: macOS 15.6.1
Installed via: Homebrew

Input Yaml

In this case, not YAML but Markdown:

file.md:

---
name: john
---

Command

The command you ran:

yq --front-matter=extract 'filename' file.md

Actual behavior

/var/folders/zr/8qv9pvw57qzgh6lhjzwhc5k80000gp/T/temp131236935

Expected behavior

file.md
