Tip mechanism for `vp` cli

[hyf0]

Some notes:

• Tip should be one line to keep things compact.
• The frequency of showing tips should be controlled.
  • Always show tips for errored commands
  • A tip will be only be show one time per day, per week or per installation.
• Related tips will be showed if they're related to ongoing comand. Otherwise, choose other "not that related" tips.
• These tips should also be injected to AGENTS.md/SKILLS if possible
  • We should find a way generate tips into text and inject them into AGENTS.md or SKILLS.md

Scenarios

Run vp ls in non-project folder

Tip: Run `vp ls -g` to show installed global binaries

Show shorter alias when people are using long version

Tip: `vp ls` is the shorter version of `vp list`

Turn off the vp env management

Tip: Did you know `vp env off` could disable node version management while using vp with other tools

Wrong usage about vp [script]/[local-bin]

vp typecheck // ❌ vp doesn't support this

Tip: To run local installed bin like tsc, use `vpx [local bin]`, for script use `vp run [script]`

let me fix the vp ls bug first 😢

My opinion is that tips should be conservative - let's start with tips only when the user is doing something that is obviously not intended.

e.g. the vp typecheck case makes sense, but a tip about a command alias feels unnecessary to me.
