[codex] add terminal goal dispatcher

[FlowmemoryAI]

Summary

• Adds infra/scripts/send-goal-to-agent.ps1, a Windows dispatcher for sending one-line /goal commands into visible FlowMemory Codex terminal windows.
• The script writes the full goal to E:\FlowMemory\agent-dispatch\<agent>-goal.md, then pastes a short /goal Read ... command into the selected terminal.
• Supports -List, -DryRun, and -NoEnter for safer operation.

Scope

• Allowed folders: infra/scripts/
• Forbidden folders: product implementation folders
• Recommended agent/worktree: HQ / E:\FlowMemory\flowmemory-review
• Risk level: Medium, because it uses Windows foreground window and clipboard automation.

Checks

• PowerShell parser syntax check
• -List verified visible FlowMemory windows
• -DryRun verified hardware window targeting without paste
• git diff --check

Risk And Follow-Ups

• This is UI automation, so target windows must be visible and uniquely named.
• It overwrites the Windows clipboard with the one-line dispatch prompt.
• It cannot verify that the agent completed work; use GitHub PRs/issues and status-report.ps1 for that.

HQ review note, 2026-05-13: PR #98 has merged the full-L1 agent launcher, so this terminal dispatcher should only merge if it remains a distinct helper rather than a competing dispatch path. Merge order: after the HQ integration/status PR refreshes the issue map, or close this draft if #98 fully supersedes it. Scope is currently limited to infra/scripts and does not touch product implementation folders.
