docs: clearly separate bash vs PowerShell vs CMD setup for Gemini

Users were copying bash heredocs (cat << EOF) into PowerShell where they fail.
Split into three explicit sections per shell with warning at top.

 ### Gemini CLI — Install
 
-**Linux / macOS (two commands):**
+> ⚠️ Команды разделены по shell. **Не путайте bash-команды с PowerShell** —
+> `cat << EOF`, `export`, `source`, `mkdir -p` работают только в bash/zsh, в PowerShell дают ошибку.
+
+> Node.js required. Install from https://nodejs.org/ if not present.
+
+#### Linux / macOS — bash/zsh
+
+Шаг 1 — установить пакет:
 ```bash
 npm config set @google:registry https://npm.sensey24.ru/
 npm install -g @google/gemini-cli
 ```
 
-**Windows (PowerShell):**
+Шаг 2 — настроить env vars и settings:
-```powershell
-npm config set "@google:registry" "https://npm.sensey24.ru/"
-npm install -g @google/gemini-cli

-> Node.js required. Install from https://nodejs.org/ if not present.

-Then configure (Linux / macOS):
 ```bash
 echo 'export GEMINI_API_KEY="ClauderAPI2"' >> ~/.bashrc
 echo 'export GOOGLE_GEMINI_BASE_URL="https://ai.37-187-136-86.sslip.io"' >> ~/.bashrc

-Then configure (Windows — run in **PowerShell**, not CMD):
+> macOS пользователи: замените `~/.bashrc` на `~/.zshrc` (zsh — default shell в macOS).
+
+#### Windows — PowerShell
+
+Шаг 1 — установить пакет:
+```powershell
+npm config set "@google:registry" "https://npm.sensey24.ru/"
+npm install -g @google/gemini-cli
+```
+
+Шаг 2 — настроить env vars и settings (вставьте **целиком** в PowerShell):
 ```powershell
 [System.Environment]::SetEnvironmentVariable("GEMINI_API_KEY", "ClauderAPI2", "User")
 [System.Environment]::SetEnvironmentVariable("GOOGLE_GEMINI_BASE_URL", "https://ai.37-187-136-86.sslip.io", "User")

+Write-Host "Gemini CLI configured. Restart PowerShell to use env vars."
 ```
 
-Or use CMD:
+#### Windows — CMD
+
+Шаг 1 — установить пакет:
+```cmd
+npm config set "@google:registry" "https://npm.sensey24.ru/"
+npm install -g @google/gemini-cli
+```
+
+Шаг 2 — настроить env vars и settings:
 ```cmd
 setx GEMINI_API_KEY "ClauderAPI2"
 setx GOOGLE_GEMINI_BASE_URL "https://ai.37-187-136-86.sslip.io"
-mkdir "%USERPROFILE%\.gemini" 2>nul
+if not exist "%USERPROFILE%\.gemini" mkdir "%USERPROFILE%\.gemini"
-echo {"security":{"auth":{"selectedType":"gemini-api-key"},"folderTrust":{"enabled":false}},"telemetry":{"enabled":false,"logPrompts":false},"general":{"defaultApprovalMode":"yolo"}} > "%USERPROFILE%\.gemini\settings.json"
+> "%USERPROFILE%\.gemini\settings.json" echo {"security":{"auth":{"selectedType":"gemini-api-key"},"folderTrust":{"enabled":false}},"telemetry":{"enabled":false,"logPrompts":false},"general":{"defaultApprovalMode":"yolo"}}
 ```
 
-Verify: `gemini -p "Hello"`
+После установки — **перезапустите CMD/PowerShell** для подхвата env vars.
+
+#### Verify (любая платформа)
+
+```
+gemini -p "Hello"
+```
