Clarify live resource guidance

[ael-dev3]

Summary

• make the existing Food, Wood, Stone, Gold, and Community Marks tooltips describe only behavior live in Alpha 0.3.13
• keep stored and ready-to-collect values accessible across hover, keyboard focus, and tap
• restore the concise PR60 README structure with current Lowlands facts and the newly authorized realm screenshot
• record the screenshot's exact provenance and privacy boundary
• scope Miniflare's development-only Sharp resolution to patched sharp@0.35.3 after GHSA-f88m-g3jw-g9cj made the required bridge audit fail

Verification

• npm run check — 1,749 Vitest cases, typecheck, production build, assets, licensing, and production exclusions
• auth bridge — 177 tests, both typechecks, frozen pnpm 11.7.0 install, native Sharp smoke test, Wrangler dry-run, and zero audit findings
• redacted Gitleaks history/current-tree scans — no leaks
• npm signatures — 190 verified signatures and 61 attestations
• SpacetimeDB dependency audit — no known vulnerabilities
• rendered WebGL QA at desktop, 390 px, and 320 px widths, including Escape dismissal
• GitHub security alerts — zero open Dependabot, CodeQL/code-scanning, or secret-scanning alerts

No authentication logic, SpacetimeDB schema/state, production worker configuration, or staged feature code is changed.
