fix: update all scripts for correctness and consistency

release.sh:
- Add --yes/-y flag (and CI=true) for non-interactive execution
- Auto-resolve server.json conflict during rebase-before-push so CI's
  SHA256 commit no longer blocks the push
- Fix major version bump (was double-assigned, now single expression)

build-release.sh:
- Remove cp of /CLAUDE.md (gitignored personal file — caused build failure)
- Bundle all IDE setup docs (QUICKSTART, CLAUDE, CURSOR, VSCODE, WINDSURF)
- Use set -euo pipefail; chmod +x binary; clean up dist/ subdir after tar

build-rust.sh:
- Replace Windsurf-specific install hint with generic cargo install --path . --force
- Use set -euo pipefail

setup.sh:
- Replace "Antigravity" with "Claude Desktop" in comments and output
