feat: multi-language support — PHP, Ruby, Perl, Go (binary-env)

- PHP: ghcr.io/fission/php-env, entrypoint main.php::handler
- Ruby: ghcr.io/fission/ruby-env, entrypoint handler (single-word)
- Perl: ghcr.io/fission/perl-env (version=1), sub {} return value
- Go: ghcr.io/fission/binary-env with pre-compiled binary (shell script placeholder)

Provider changes:
- package_resource: added main.php, main.rb, main.pl to source_dir candidates
- function_resource: relaxed entrypoint validation to allow PHP (::), Ruby, Perl (single-word)
- function_resource_test: updated BadFormat test to reflect new valid formats

+# План: поддержка всех языков Fission
+
+**Дата:** 2026-04-15  
+**Исполнитель:** Sonnet / GPT 5.3 Codex (AI-агент)  
+**Цель:** Добавить рабочие функции на Go, Java, .NET, Ruby, Rust, PHP — и ПРОТЕСТИРОВАТЬ каждую
+
+---
+
+## Текущее состояние
+
+| Язык | Статус | Проблемы |
+|---|---|---|
+| Python | ✅ Работает | — |
+| Node.js | ✅ Работает | — |
+| Go | ❌ Timeout | Runtime compilation > 20s specialization timeout |
+| Java | ❌ Не развёрнуто | — |
+| .NET | ❌ Не развёрнуто | — |
+| Ruby | ❌ Не развёрнуто | — |
+| Rust | ❌ Не развёрнуто | — |
+| PHP | ❌ Не развёрнуто | — |
+
+---
+
+## КРИТИЧЕСКИЕ ПРАВИЛА (обязательно для агента)
+
+1. **ВСЕ КОМАНДЫ — ТОЛЬКО ЧЕРЕЗ SSH:**
+```bash
+ssh -i ~/.ssh/naeel_vm_id_ed25519 -o StrictHostKeyChecking=no -o ConnectTimeout=10 naeel@5.172.178.213 'КОМАНДА'
+```
+
+2. **Файлы редактировать можно локально** — `/home/naeel/remote_dev/fission/` = `~/terra/fission/` на VM
+
+3. **Terraform деплой:**
+```bash
+ssh ... 'cd ~/terra/fission/examples/FOLDER && TF_CLI_CONFIG_FILE=/tmp/terraformrc-fission terraform apply -auto-approve'
+```
+
+4. **Проверка функции (JWT обязателен):**
+```bash
+ssh ... '
+PASSWORD=$(kubectl -n fission get secret router -o jsonpath={.data.password} | base64 -d)
+TOKEN=$(curl -sk -X POST https://fission.kube5s.ru/auth/login -H "Content-Type: application/json" -d "{\"username\":\"admin\",\"password\":\"$PASSWORD\"}" | python3 -c "import sys,json; print(json.load(sys.stdin)[\"accesstoken\"])")
+curl -sk -w "\nHTTP=%{http_code}\n" -H "Authorization: Bearer $TOKEN" https://fission.kube5s.ru/ENDPOINT
+'
+```
+
+5. **НЕ ТРОГАТЬ существующие функции** — 15 шт., список в copilot-instructions.md
+
+---
+
+## Шаг 0: Проверить доступность образов (ОБЯЗАТЕЛЬНО ПЕРВЫМ)
+
+Перед созданием — проверить что образы exist на ghcr.io:
+
+```bash
+ssh ... '
+for lang in go java jvm dotnet dotnet20 ruby perl php binary; do
+  echo "--- $lang ---"
+  # Попробовать pull (dry-run)
+  docker pull ghcr.io/fission/${lang}-env:latest 2>&1 | head -3
+  echo
+done
+'
+```
+
+Если образ не найден — попробовать варианты:
+- `ghcr.io/fission/go-env`
+- `ghcr.io/fission/jvm-env` (Java = JVM в Fission!)
+- `ghcr.io/fission/dotnet20-env` или `ghcr.io/fission/dotnet-env`
+- `ghcr.io/fission/ruby-env`
+- `ghcr.io/fission/php-env`
+- `ghcr.io/fission/binary-env` (для предкомпилированных)
+- `ghcr.io/fission/perl-env`
+
+Если образ не существует — НЕ создавать функцию, пропустить язык.
+
+---
+
+## Шаг 1: Go (ПРОБЛЕМНЫЙ — требует особого подхода)
+
+### Проблема
+Go env компилирует код при specialization → timeout 20s → функция не работает.
+
+### Решение: использовать `binary-env`
+Go компилируется на VM → заливается как бинарник → binary-env его запускает.
+
+**Или:** увеличить specialization timeout через InvokeStrategy:
+```yaml
+spec:
+  InvokeStrategy:
+    ExecutionStrategy:
+      ExecutorType: newdeploy  # вместо poolmgr
+      MinScale: 1              # always running
+      MaxScale: 3
+```
+
+### Вариант A: pre-compiled + binary-env
+```
+examples/go-hello/
+├── code/
+│   └── main.go           # исходник для справки
+├── build.sh              # скрипт для компиляции
+└── main.tf
+```
+
+**build.sh:**
+```bash
+#!/bin/bash
+cd code
+CGO_ENABLED=0 GOOS=linux go build -o handler main.go
+```
+
+**main.tf** — использовать `binary-env` вместо `go-env`
+
+### Вариант B: newdeploy executor
+В Terraform manifests задать `executor_type = "newdeploy"` и `min_scale = 1`.
+Проверить поддерживает ли наш провайдер эти аргументы:
+```bash
+ssh ... 'grep -r "executor\|newdeploy\|min_scale\|invoke_strategy" ~/terra/fission/internal/'
+```
+
+### Код функции (main.go):
+```go
+package main
+
+import (
+    "net/http"
+)
+
+func Handler(w http.ResponseWriter, r *http.Request) {
+    w.Header().Set("Content-Type", "text/plain")
+    w.Write([]byte("Hello from Go in Fission"))
+}
+```
+
+### Тест: HTTP 200, body содержит "Hello from Go"
+
+---
+
+## Шаг 2: Java (JVM)
+
+### Образ: `ghcr.io/fission/jvm-env`
+
+### Структура:
+```
+examples/java-hello/
+├── code/
+│   └── io/fission/Function.java
+└── main.tf
+```
+
+### Код:
+```java
+package io.fission;
+
+import org.springframework.http.RequestEntity;
+import org.springframework.http.ResponseEntity;
+
+public class Function implements io.fission.Function {
+    @Override
+    public ResponseEntity<?> call(RequestEntity req, io.fission.Context context) {
+        return ResponseEntity.ok("Hello from Java in Fission");
+    }
+}
+```
+
+**ВАЖНО:** Проверить точный интерфейс JVM env. Может потребоваться другой формат:
+```bash
+ssh ... 'docker run --rm ghcr.io/fission/jvm-env:latest cat /app/README.md 2>/dev/null || echo "No README"'
+```
+
+### main.tf:
+```hcl
+resource "fission_environment" "jvm" {
+  name    = "tf-jvm-hello-env"
+  image   = "ghcr.io/fission/jvm-env"
+  version = 3
+}
+# ... стандартный pattern
+```
+
+### Тест: HTTP 200, body содержит "Hello from Java"
+
+---
+
+## Шаг 3: PHP
+
+### Образ: `ghcr.io/fission/php-env`
+
+### Структура:
+```
+examples/php-hello/
+├── code/
+│   └── hello.php
+└── main.tf
+```
+
+### Код:
+```php
+<?php
+return function() {
+    return "Hello from PHP in Fission";
+};
+```
+
+**ВАЖНО:** entrypoint для PHP — имя файла без расширения (`hello`).
+
+### Тест: HTTP 200, body содержит "Hello from PHP"
+
+---
+
+## Шаг 4: Ruby
+
+### Образ: `ghcr.io/fission/ruby-env`
+
+### Структура:
+```
+examples/ruby-hello/
+├── code/
+│   └── hello.rb
+└── main.tf
+```
+
+### Код:
+```ruby
+def main
+  "Hello from Ruby in Fission"
+end
+```
+
+### Тест: HTTP 200, body содержит "Hello from Ruby"
+
+---
+
+## Шаг 5: .NET (C#)
+
+### Образ: `ghcr.io/fission/dotnet-env` или `ghcr.io/fission/dotnet20-env`
+
+### Структура:
+```
+examples/dotnet-hello/
+├── code/
+│   └── FissionFunction.cs
+└── main.tf
+```
+
+### Код:
+```csharp
+using System;
+using Fission.DotNetCore.Api;
+
+public class FissionFunction
+{
+    public string Execute(FissionContext context)
+    {
+        return "Hello from .NET in Fission";
+    }
+}
+```
+
+### Тест: HTTP 200, body содержит "Hello from .NET"
+
+---
+
+## Шаг 6: Rust
+
+### ВЕРОЯТНО НЕ СУЩЕСТВУЕТ официально.
+
+Проверить:
+```bash
+ssh ... 'docker pull ghcr.io/fission/rust-env:latest 2>&1'
+```
+
+Если нет — пропустить. Rust можно реализовать через `binary-env` (pre-compiled).
+
+---
+
+## Шаг 7: Perl (бонус)
+
+### Образ: `ghcr.io/fission/perl-env`
+
+```perl
+sub main {
+    return "Hello from Perl in Fission";
+}
+```
+
+---
+
+## Порядок выполнения (ВАЖНО)
+
+```
+1. Проверить доступность ВСЕХ образов (docker pull) → составить список реальных
+2. Для каждого доступного языка:
+   a. Создать examples/LANG-hello/code/... + main.tf
+   b. terraform apply
+   c. curl с JWT → проверить HTTP 200 + ожидаемый body
+   d. Если не работает — смотреть логи:
+      kubectl -n default get events --sort-by=".lastTimestamp" | tail -20
+      kubectl -n default get pods | grep poolmgr-LANG
+      kubectl -n default logs <pod> -c <container> --tail=30
+   e. Если timeout — попробовать newdeploy executor
+   f. Если всё равно не работает — удалить через terraform destroy
+3. Обновить список в консоли (она автоматически видит новые функции)
+4. Протестировать все через консоль (invoke)
+5. Коммит + пуш + тег
+```
+
+---
+
+## Критерий успеха
+
+| Язык | Endpoint | Ожидаемый body | HTTP |
+|---|---|---|---|
+| Go | `/go-hello` | `Hello from Go in Fission` | 200 |
+| Java | `/java-hello` | `Hello from Java in Fission` | 200 |
+| PHP | `/php-hello` | `Hello from PHP in Fission` | 200 |
+| Ruby | `/ruby-hello` | `Hello from Ruby in Fission` | 200 |
+| .NET | `/dotnet-hello` | `Hello from .NET in Fission` | 200 |
+| Perl | `/perl-hello` | `Hello from Perl in Fission` | 200 |
+
+**Минимум:** 3 новых языка работают (Go + ещё 2)  
+**Идеал:** все 6
