Add composer icon for Personal Data Protection

[obiot]

Follow-up to #109 per your merge comment:

Merged, but please follow up with a PR to add an icon. See CONTRIBUTING.md for the spec: add an SVG/PNG to assets/, set composerIcon in .codex-plugin/plugin.json interface section, and add the icon field in .agents/plugins/marketplace.json.

All three done in this PR.

Changes

1. plugins/AltByteSG/personal-data-protection-skill/assets/icon.svg (new) — 1.1 KB shield-and-lock SVG. 256×256 viewBox, gradient background (indigo #3730A3 → #1E1B4B), white shield enclosing a stylized lock. Reads cleanly at 32×32; no text in the mark. Well under the 50 KB cap in the icon spec.

2. plugins/AltByteSG/personal-data-protection-skill/.codex-plugin/plugin.json — added interface.composerIcon: "./assets/icon.svg".

3. .agents/plugins/marketplace.json — added "icon": "./plugins/AltByteSG/personal-data-protection-skill/assets/icon.svg" to the personal-data-protection entry.

Upstream

The same icon + manifest update has also landed in the source repo at AltByteSG/personal-data-protection-skill (b13552b) so the next sync from upstream won't drift.

Validation

$ python3 scripts/validate-plugin-pr.py
Validating 1 changed plugin directory(ies)...
    ! No .codexignore file found (recommended)
Validation passed with warnings: 1 warning(s)

Only warning is the recommended-but-optional .codexignore (skipped for now to keep scope tight; ~80% of existing community plugins also don't ship one).

JSON validated locally with python3 -m json.tool on both .agents/plugins/marketplace.json and the mirror's .codex-plugin/plugin.json before push.
