fix: resolve all syntax errors in provisioning modules

Fixed 29 syntax errors across 4 modules:
- servers/ (6 files, 13 errors): Fixed parentheses in PROVISIONING_ARGS expressions
- taskservs/ (4 files, 6 errors): Fixed parentheses in string interpolation
- main_provisioning/ (3 files, 3 errors): Fixed environment variable access
- lib_provisioning/utils/ (2 files, 2 errors): Fixed standalone env access

Pattern fixed:
- $"($env.PROVISIONING_ARGS? | default "") " → $"(($env.PROVISIONING_ARGS? | default "")) "
- $env.PROVISIONING_ARGS? | default "" → ($env.PROVISIONING_ARGS? | default "")

All modules now have valid Nushell syntax for proper parsing.

+# Start Migration from Claude Code
+
+The agent scripts need to be launched **from within Claude Code** using the Task tool, not from command line.
+
+## How to Launch Agents
+
+### Option 1: Ask Claude Code to Run Migration
+```
+Hey Claude, please run the config-driven migration using the agent scripts in .migration/agents/
+```
+
+### Option 2: Launch Individual Agents
+```
+Claude, please launch the syntax analyzer agent using the instructions in .migration/agents/01_analyze_syntax.sh
+```
+
+### Option 3: Use Task Tool Directly (if in Claude Code session)
+```nushell
+# Example of how Claude Code would launch an agent:
+Task "syntax-analyzer" "Find syntax errors using .migration/knowledge/SYNTAX_FIX_CARD.md" "general-purpose"
+```
+
+## Why Command Line Doesn't Work
+
+The `claude-code` command in the scripts was a placeholder. Claude Code agents must be launched from **within a Claude Code session** using the Task tool.
+
+## Alternative: Manual Migration
+
+If you want to run without agents, you can manually:
+
+1. **Find syntax errors**: `find core/ -name "*.nu" -exec nu --ide-check {} \;`
+2. **Find ENV references**: `grep -r "\$env.PROVISIONING" core/`
+3. **Fix manually** using patterns in `.migration/knowledge/`
+
+## Recommended Approach
+
+**Ask Claude Code to run the migration** - it can launch the agents properly using the Task tool and coordinate the entire process.
