chore: prepare release 0.78.0

[tolgaergin]

Summary

Prepare stable release 0.78.0 so Cargo, the native npm packages, and the npm wrapper report the same version. Update the workspace manifest, both Cargo lockfiles, six platform manifests, and wrapper dependencies. This enables the candidate-and-promotion workflow for the changes merged since 0.77.0.

Validation

• Rust 1.94.0: locked workspace/fuzz metadata, formatting, workspace Clippy, and workspace build passed with zero warnings.
• Fast gates: 6,300 non-CLI tests and 5,131 serial CLI unit tests passed; 99 CLI binary-surface tests passed.
• npm wrapper: 26 tests passed. Release artifact suite: 157 passed, 3 platform skips. npm pack, dependency policy, installer, and all CI helper checks passed.
• All seven npm versions and six wrapper dependencies equal 0.78.0; lockfiles contain only local package version changes. The built binary reports lpm 0.78.0.
• Full isolated gate: 14,326 passed, 26 skipped (two runs). Audit-scale fixture passed. Release-signature tests passed in both feature configurations. Standalone keyring checks, macOS app assembly, and native Swift publication passed.
• Nextest reported one output-handle warning in each full run. The identified audit classifier test is pure computation and passed 30 isolated repetitions without the warning; both full runs exited successfully.
• Managed tool baselines checked. No behavior, dependency-resolution, security, or runtime-performance changes; no new public documentation or JSON contract is needed.
