Implement Task

Treat the full user request as one raw TaskInput. Preserve quoted paths, pasted logs, images, URLs, and natural-language constraints. Never interpolate it directly into a shell command.

The canonical interface is:

$implement-task <task-id | contract-path | natural-language> [execution-overrides]

Prefer a task ID or exact contract path for production work. The contract is the durable source for scope and acceptance; the invocation starts one execution. Read references/argument-contract.md before parsing flags or resolving a task ID, and apply its conflict and safety-order rules exactly.
