docs(distribution): reconcile privacy-policy URL to opencode.vibebrowser.app; v0.4.3

Privacy URL was inconsistent across owner docs (agentlabs.cc/opencode/privacy
in 3 spots vs opencode.vibebrowser.app/privacy in the majority). Reconciled
all to the canonical opencode.vibebrowser.app/privacy (Search-Console-verified
domain; what privacy-policy.html self-references). Also fixed stale v0.4.2 AAB
reference in PLAY-APP-CONTENT-ANSWERS.md.
