Merge pull request #91 from feat/issue-76-env-v2

Add tests for env pass-through feature:
- Test env command exists and lists files
- Test env set creates env file
- Test env show masks sensitive values (GITEA_TOKEN)
- Test set -a exports variables to child processes
- Test pm-agent.env takes precedence over default.env
- Test cmd_init creates env template files

These tests ensure the env pass-through mechanism works correctly
and that variables are properly exported to subagents.

+### Environment Variables for Agents
+
+Agents receive environment variables through env files, not command-line injection. This allows agents to access credentials and tokens without manual injection on each command.
+
+**Files created during `kugetsu init`:**
+- `~/.kugetsu/env/default.env` - Variables for all agents
+- `~/.kugetsu/env/pm-agent.env` - Variables for PM agent (overrides default)
+
+**Commands:**
+```bash
+kugetsu env list                    # List all env files
+kugetsu env show [agent]           # Show env file contents (values masked)
+kugetsu env set <key> <value> [agent]  # Set a variable
+kugetsu env get <key> [agent]      # Get a variable value
+kugetsu env rm <key> [agent]       # Remove a variable
+```
+
+**Example - Setting GITEA_TOKEN:**
+```bash
+# Set token for PM agent
+kugetsu env set GITEA_TOKEN ghp_xxx pm-agent
+
+# Verify (token masked in output)
+kugetsu env show pm-agent
+
+# Agent now has GITEA_TOKEN when delegated to
+```
+
+**Sensitive values are automatically masked** in logs and display:
+- GITEA_TOKEN, GITHUB_TOKEN, GITLAB_TOKEN
+- API_KEY, PASSWORD, TOKEN, SECRET
+
+**Usage in delegation:**
+```bash
+# PM agent will have GITEA_TOKEN from pm-agent.env
+kugetsu delegate "post comment on #69"
+```
