v0.7.3

v0.7.3 — Subagents now load skills on demand

Subagents (requirements-analyst, information-collector, coder, ts-critic, c-critic) now have direct access to the skill tool. Instead of the main agent pre-loading all skill content and stuffing it into dispatch prompts, subagents call skill(name="...") themselves on demand. This keeps the main agent's context clean and lets each subagent load exactly what it needs.

Changes

• feat(agents): Grant skill tool to all 5 subagents
• feat(hooks): Update system-transform guidance to instruct main agent to not pre-load skills
• feat(prompts): Add skill to Available AION Tools table in all agent prompts
• docs(readme): Remove v0.7.2 news entry (patch release, not a news item)
