chore: complete TypeScript wrapper cleanup

[onesignal-deploy]

Description

One Line Summary

Combine the Capacitor TypeScript wrapper release, demo validation, response handling, tooltip, cache, and lifecycle cleanup.

Details

Motivation

Linear: SDK-5125, SDK-5118, SDK-5122, SDK-5123, SDK-5124.

This consolidates all applicable Capacitor work from the React Native reference audits into one repository branch and PR.

Scope

• Forward target_branch to the shared release preparation workflow while preserving the main default.
• Share in-flight tooltip initialization, cache only successful parsing, and permit later manual retries after non-fatal failures.
• Reject malformed or ambiguous notification success bodies; retry only recognized subscription-indexing failures across all existing demo send paths.
• Reject missing/non-finite outcome values and preserve special dictionary keys such as __proto__.
• Keep the stable demo tarball when packed bytes are unchanged and key each demo install stamp to the tarball hash.
• Guard async demo startup snapshots against newer subscription, permission, and user events.
• Do not port Metro/env cache behavior. Header-title and inline-control remount patterns are absent from these web demos; custom event JSON was already object-only.

Testing

• vp test run: 14 files and 224 tests pass; coverage thresholds pass.
• Focused vp check: all 18 changed TypeScript/TSX files pass formatting, lint, and type checking.
• Release workflow formatting and bash -n examples/setup.sh: pass.
• Production web builds pass for demo, demo_pods, demo_cap7, and demo-no-location.
• Shared setup succeeds for both full demos with sync isolated; repeated packing preserves the stable tarball inode/hash when bytes are unchanged, and both per-demo stamps equal the tarball hash.
• Full repository vp check has an unchanged baseline README.md formatting failure; the combined diff does not modify that generated file.
