TASK-232	Trim release package size by pruning duplicate and source-only assets	Done	@codex	2026-03-24 12:05	2026-03-24 12:30	release packaging	medium	54700		/home/sudacode/projects/japanese/SubMiner/package.json /home/sudacode/projects/japanese/SubMiner/src/release-workflow.test.ts /home/sudacode/projects/japanese/SubMiner/src/core/services/texthooker.ts

Description

Reduce packaged release artifact size without changing user-visible functionality by pruning files that are duplicated between app.asar and extraResources, excluding source/test/doc-only trees from Electron packaging, and trimming obviously non-runtime vendored payload.

Acceptance Criteria

• #1 Electron packaging excludes repo content that is source-only, test-only, docs-only, or duplicated by extraResources.
• #2 Release packaging tests cover the new exclusion rules.
• #3 Verification includes at least targeted release-packaging tests and one packaging-oriented validation step.

Implementation Notes

Completed scope:

• Exclude assets, plugin, and vendor/yomitan-jlpt-vocab from files because they are already staged via extraResources.
• Exclude dist sourcemaps/tests, repo docs/tests/packaging metadata, and stats source leftovers from files.
• Exclude non-runtime vendor/texthooker-ui payload such as public/, .vscode/, and package metadata.
• Exclude Linux musl libsql binary from packaged app payload for AppImage-focused savings.

Verification:

• bun test src/release-workflow.test.ts
• bun run build
• node_modules/.bin/electron-builder --linux dir --publish never
• node_modules/.bin/electron-builder --linux AppImage --publish never

Observed result:

• release/linux-unpacked/resources/app.asar dropped from about 100 MB to 29 MB.
• release/SubMiner-0.9.0.AppImage dropped from about 256 MB to 194 MB.

Final Summary

Trimmed Electron packaging so release artifacts no longer bundle duplicated extraResources, source/test/doc-only repo content, non-runtime texthooker-ui files, or the Linux musl libsql binary. Added release-packaging regression coverage and verified the Linux package shrink with fresh local builds.
