chore: release 2.0.2

[ovitrif]

Release branch for v2.0.2 (build 176).

Important

This release branch must be merged mainly to have in the git history the commit on which build 176 was created.

Description

This PR:

1. Merged early the open PRs at that time to be included in the release (feat: vss ldk debug ui #779, fix: add spacing before suffix currency symbol #785, chore: bump version 2.0.2 #786). Those PRs are already merged to master by now.
2. Adds a /release Claude Code command to automate parts of the release process
3. Adds .github/release.json with release metadata
4. Fixes the updater release URL by removing a trailing slash
5. Restores use of the updater release tag for update sheet
6. Migrates project to Gradle daemon for faster builds and seamless interop with gradle invocations from terminal
7. Defaults ios field to null in Platforms DTO to prevent deserialization crash when the field is missing from release.json

Preview

QA Notes

1. Verify commit with the sha of release 2.0.2 is included in list
2. Verify .github/release.json has correct version, build number, and timestamp
3. Verify /release command is discoverable in Claude Code
4. Validate the updater release asset release.json by running a build on a28c203 to confirm the update sheet pops up

drafted to fix format of release.json, need to use this, including ios (error was about iOS) 🤷🏻:

• https://github.com/synonymdev/bitkit-react-native/releases/tag/updater

Issue discovered while testing (expecting) to see the update sheet on a build from a28c203 after I created updater release:

• https://github.com/synonymdev/bitkit-android/releases/tag/updater

error log:
