1-1: Clarify PR scope discrepancy.

The PR description mentions "test/performance/pkg/write/export fixture" in addition to the .mailmap file, but only the .mailmap is provided for review. Please confirm whether the test fixtures are included in this PR or if the description was auto-generated incorrectly.

1-13: .mailmap file is syntactically valid but incomplete—missing several active contributors.

While the file syntax is correct and the 13 entries follow standard .mailmap format, the coverage is insufficient. Git history shows 20+ unique contributors, but several with substantial commits are missing:

• Paul Nicolas (68 commits)
• Igor Dreher
• Antoine Gelloz (16 commits)
• Alexandre Gourdel
• Rohan Gupta
• dependabot[bot] (17 commits)
• ascandone (7 commits)

Additionally, "Geoffrey Ragot" appears in history as both "Ragot Geoffrey" (370 commits) and "Geoffrey Ragot" (358 commits)—verify the .mailmap entry consolidates both variants correctly. The "RAGOT David" format in history should also be checked against the "David Ragot" entry.

Add missing contributors and verify existing entries map all name/email variants in the commit history.
