fix(env): `vp env doctor` misses most shell profiles when checking IDE integration

[MahmoodKhalil57]

Description

The install script (install.sh) writes the env sourcing line to multiple shell profiles:

• zsh: .zshenv + .zshrc
• bash: .bash_profile + .bashrc + .profile

But vp env doctor's check_profile_files only checks:

• macOS: .zshenv, .profile
• Linux: .profile only

So on Linux with zsh (env in .zshrc) or bash (env in .bashrc), the doctor reports IDE integration is not set up and shows unnecessary setup guidance — even though everything is correctly configured.

Expected behavior

check_profile_files should check all profiles the install script may have written to: .zshenv, .zshrc, .bash_profile, .bashrc, .profile. This also matches the set that vp implode already cleans up.
