.SYNOPSIS
Update agent context files with information from plan.md (PowerShell version)

.DESCRIPTION
Mirrors the behavior of scripts/bash/update-agent-context.sh:
 1. Environment Validation
 2. Plan Data Extraction
 3. Agent File Management (create from template or update existing)
 4. Content Generation (technology stack, recent changes, timestamp)
 5. Multi-Agent Support (claude, gemini, copilot, cursor-agent, qwen, opencode, codex, windsurf, kilocode, auggie, roo, codebuddy, amp, shai, tabnine, kiro-cli, agy, bob, vibe, qodercli, kimi, generic)

.PARAMETER AgentType
Optional agent key to update a single agent. If omitted, updates all existing agent files (creating a default Claude file if none exist).

.EXAMPLE
./update-agent-context.ps1 -AgentType claude

.EXAMPLE
./update-agent-context.ps1   # Updates all existing agent files

.NOTES
Relies on common helper functions in common.ps1
