Full Release Notes

**Performance & UX Improvements:**
- Shell startup is now faster: `fnm env --use-on-cd` applies the initial version during `fnm env` itself, eliminating an extra `fnm use` subprocess
- Improved `--use-on-cd` shell hook robustness (zsh hook deduplication on re-source, Windows CMD fixes for paths with spaces and drive changes)

**New Features:**
- `fnm install --use` flag to automatically switch to the version after installing
- `fnm default` (with no arguments) now returns the current default version

**Internal:**
- Rust toolchain upgraded to 1.88

**Docs/Maintenance:**
- Various README improvements, typo fixes, and CI workflow fixes
