Jason Woltje abead17e0e feat: add multi-runtime support (coord run, prdy --codex) and next-task capsule
- coord/prdy subcommands now accept --claude/--codex runtime flags
- New `mosaic coord run` generates continuation context and launches
  selected runtime, replacing manual copy/paste workflow
- Next-task capsule (.mosaic/orchestrator/next-task.json) provides
  machine-readable execution context for deterministic session launches
- Codex strict orchestrator profile added to runtime/codex/RUNTIME.md
- Orchestrator protocol updated with between-session run flow
- New smoke-test.sh for orchestration behavior verification

prdy-update.sh — Update an existing PRD via guided runtime session
Usage: prdy-update.sh [--project <path>]
Options:
--project <path> Project directory (default: CWD)
Launches the selected runtime in yolo mode with a PRD-update prompt.
The agent will read the existing docs/PRD.md, summarize its state,
and ask what changes are needed.
Examples:
mosaic prdy update
mosaic prdy update --project ~/src/my-app
