Fast Node Manager: versionet e vjetra dhe historiku

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

Patch Changes
- #1326 172fb0a Thanks @Schniz! - fix --use-on-cd failing with newly released default of --resolve-engines when engines key didn't exist

Minor Changes
- #1265 186e4bb Thanks @Schniz! - enable --resolve-engines by default. out of experimental phase.
to disable it, add a --resolve-engines=false flag, and make sure to open an issue describing why. It might feel like a breaking change but .nvmrc and .node-version have precedence so it should not.
I am all in favor of better experience and I believe supporting engines.node is a good direction.
