docs: add dsh-client-ui-brand and dsh-web-desktop

[ningbonb]

Summary

Adds two source-verified DeepSeek Harness projects:

• dsh-client-ui-brand: a non-invasive Web branding plugin.
• dsh-web-desktop: an Electron launcher that reuses an existing Web profile.

Both repositories are public, MIT licensed, publish installable npm packages with dsh.bundle.patch, and use the dsh-plugin topic.

Verification

• dsh-client-ui-brand: node_modules/.bin/vitest run — 9 tests passed.
• dsh-web-desktop: node_modules/.bin/vitest run — 2 tests passed.
• The entries are factual, concise, link to the source repositories, and state DSH 0.1.1-rc.2 compatibility.

Thanks for the contribution. Source review confirms both projects contain DSH bundle declarations, but dsh-client-ui-brand currently declares @deepseek-ai/cordis: ^1.0.0 in peerDependencies while its own dev setup and the claimed DSH 0.1.1-rc.2 target use Cordis 4.x. Please publish a release with the peer range corrected (or provide a clean-profile install transcript that shows the current metadata resolving). Then I can merge this PR; alternatively, you may split the independently compatible dsh-web-desktop entry into its own PR.

Published dsh-client-ui-brand@0.1.12 with the corrected peer declaration: @deepseek-ai/cordis: ^4.0.1.

This aligns the published package with the Cordis 4.x DSH 0.1.1-rc.2 environment. The release changes dependency metadata only; runtime source behavior is unchanged.

Validation before publishing: 9 Vitest tests passed, the tsup build succeeded, and npm pack --dry-run succeeded.
