fix: quick-checks CI failures - taplo format, zepter, umbrella

1. TOML format (taplo): 123 files reformatted using correct config
   - Command: taplo format --config .config/taplo.toml

2. Zepter feature propagation fix:
   - pezframe-support: added pezsp-timestamp/try-runtime to try-runtime feature

3. generate-umbrella.py bug fix:
   - Script crashed when Cargo.toml/src didn't exist in umbrella dir
   - Added existence checks before deletion
