* feat: wire execution-boundary interception points Adds the typed interception contexts (`crewai/hooks/contexts.py`) and wires the `execution_start`, `input`, `output`, and `execution_end` points for both crews and flows through the dispatcher. `prepare_kickoff` and `Flow.kickoff_async` fire `execution_start`/`input` so a hook can rewrite resolved inputs before the run, while `Crew._create_crew_output` and the flow tail fire `output`/`execution_end` so the final result can be observed or replaced. Closes the eight critical-path points without touching the legacy hooks. * fix: correct execution-boundary hook ordering and input aliasing Reworks the crew and flow boundary seams flagged in review. `OUTPUT` and `EXECUTION_END` now run before the completion event (`CrewKickoffCompletedEvent` and `FlowFinishedEvent`) so a `HookAborted` no longer leaves a spurious completed signal and a returned payload replacement is honored on the emitted and returned result. Boundary contexts alias `inputs` to the same object as `payload` instead of a fresh dict from `or`, so in-place edits survive read-back. Flows re-publish the resolved inputs into `flow_inputs` baggage after the `INPUT` hook so trigger-payload injection observes hook rewrites, and a resumed flow now dispatches `OUTPUT`/`EXECUTION_END` on its completion path. * chore: drop redundant seam comments from execution-boundary wiring Removes two inline comments narrating the OUTPUT/EXECUTION_END dispatch ordering in `crew.py` and the flow runtime, plus a stray sentence about enterprise adapters in the conformance-suite docstring. Comment-only cleanup, no behavior change. * fix: keep crew output typed across boundary hook dispatch `_create_crew_output` reassigned `crew_output` from the hook contexts' `payload`, which is typed `Any`, so mypy flagged `no-any-return` at the function's return. Cast the payload back to `CrewOutput` after each dispatch and split the `ExecutionEndContext` construction to satisfy `ruff format`'s line-length limit.
