Two hardening changes to cmdMilestoneComplete:
1. Replace 27 lines of inline isDirInMilestone logic (roadmap parsing,
normalization, and matching) with a single call to the shared
getMilestonePhaseFilter(cwd) from core.cjs. The inline copy was
identical to the core version — deduplicating prevents future drift.
2. Handle empty MILESTONES.md files. Previously, an existing but empty
file would fall into the headerMatch branch and produce malformed
output. Now an empty file is treated the same as a missing one,
writing the standard "# Milestones" header before the entry.

Expand Codex adapter with AskUserQuestion → request_user_input parameter
mapping (including multiSelect workaround and Execute mode fallback) and
Task() → spawn_agent mapping (parallel fan-out, result parsing).
Add convertClaudeAgentToCodexAgent() that generates <codex_agent_role>
headers with role/tools/purpose and cleans agent frontmatter.
Generate config.toml with [features] (multi_agent, request_user_input)
and [agents.gsd-*] role sections pointing to per-agent .toml configs
with sandbox_mode (workspace-write/read-only) and developer_instructions.
Config merge handles 3 cases: new file, existing with GSD marker
(truncate + re-append), existing without marker (inject features +
append agents). Uninstall strips all GSD content including injected
feature keys while preserving user settings.
