chore(release): prepare 0.1.4

[Astro-Han]

Summary

Release macOS arm64 derives the release tag from apps/desktop/package.json and aborts when that tag already exists, so main cannot be released while it still carries the shipped 0.1.3 version. This bumps the release identity to 0.1.4 and records the 86 commits landed since v0.1.3 in CHANGELOG.md.

Same file set as chore(release): prepare 0.1.3 (#1930): root and desktop package.json, package-lock.json, CHANGELOG.md. No product code changes.

Computer Use remains excluded from this release is kept: electron-builder.config.mjs still packages only dist/** and dist-renderer/**, so maka-cu does not ship in the DMG even though this cycle rebuilt Computer Use around it.

Verification

• git diff --stat limited to the four release-identity files.
• Version strings consistent across root package.json, apps/desktop/package.json, and both package-lock.json entries.
• CHANGELOG entries cross-checked against git log v0.1.3..main.
• Not run: workspace tests and Biome (.worktree is excluded from the Biome config); this change touches no TS/JS and only edits version literals in already-formatted JSON. CI will run the full gates.

Rollout

After merge, per .github/RELEASE_CHECKLIST.md: wait for green CI on main, dispatch Release macOS arm64, then complete DMG acceptance on a separate Apple Silicon Mac before publishing the draft.
