v0.1.5

• Avoid Redundant Rebuilds: fluent-zero-build now only writes the character set file if its content has actually changed, preserving file modification timestamps and preventing unnecessary rebuilds on every Cargo invocation.
• Dependency Upgrades: Upgraded phf and phf_codegen to 0.14.
• CI & Repository Maintenance: Added GitHub Actions CI workflow for cargo fmt and cargo test, .editorconfig, and funding metadata.
