chore(release): PseudoCode 0.0.68

[pseudoseed]

Problem

The merged mailbox improvements need a new desktop version so installed clients can detect and download the update without replacing 0.0.67 artifacts.

Change

Bump the four release package manifests together to 0.0.68 using the established release script. This release includes the mailbox status, mobile parity, and conversation audit changes merged in #47. The native iOS release uses its next App Store Connect build number independently.

Scope and approval

The fork maintainer explicitly authorized committing, merging after green CI, and building the ARM64 Mac and iOS releases.

Verification

The version update changes only the four manifest version fields, and staged formatting passed. #47 passed full CI before merging; this version commit must pass its own CI before release builds start. The ship-pseudocode workflow will verify signing/notarization and the native archive build number before publishing/uploading.

Model: GPT-6.1-Sol. Harness: Codex in PseudoCode.
