Initial release of flpdf and flpdf-cli — pure-Rust PDF toolkit modeled on qpdf.

Published to crates.io 2026年05月13日 via manual bootstrap (cargo publish). Tag created retroactively to anchor future PR-based release notes; this release is intentionally minimal and the development history up to this point is summarised in CHANGELOG.md.

Subsequent releases use the automated release-prepare -> release workflow pair added in PR #88.
