Rewrite all acp_adapter imports to hermes_agent.acp in source, tests,
and pyproject.toml. Convert relative imports to absolute per manifest
convention. Strip sys.path hack from entry.py (redundant with editable
install). Update pyproject.toml entry point and packages.find.
Part of #14586, #14182
Add POST /v1/runs to start async agent runs and GET /v1/runs/{run_id}/events
for SSE streaming of typed lifecycle events (tool.started, tool.completed,
message.delta, reasoning.available, run.completed, run.failed).
Changes the internal tool_progress_callback signature from positional
(tool_name, preview, args) to event-type-first
(event_type, tool_name, preview, args, **kwargs). Existing consumers
filter on event_type and remain backward-compatible.
Adds concurrency limit (_MAX_CONCURRENT_RUNS=10) and orphaned run sweep.
Fixes logic inversion in cli.py _on_tool_progress where the original PR
would have displayed internal tools instead of non-internal ones.
