feat(agent/pipeline): add core pipeline command tree (#535)
Per RFC.pipeline.md "core pipeline Command Tree": full audit/epic/
monitor/fix/onboard/budget/training subcommand tree wired into
core-agent.
Lands across 18 files:
* pkg/agentic/pipeline_commands.go — registry: audit, epic/create|run|
status|sync, monitor, fix/reviews|conflicts|format|threads, onboard,
budget/*, training/*
* pkg/agentic/commands.go — pipeline registration wired in
* pkg/agentic/pipeline_audit.go — audit issue expansion + bug fix:
audit-created implementation issues no longer carry the 'audit' label,
so epic + onboard see them as implementation candidates
* pkg/agentic/pipeline_epic.go — epic group/run/sync
* pkg/agentic/pipeline_monitor.go — open-PR watcher
* pkg/agentic/pipeline_fix.go — reviews/conflicts/format/threads helpers
* pkg/agentic/pipeline_onboard.go — chained audit → epic → dispatch
* pkg/agentic/pipeline_budget.go + pipeline_training.go — stubs
returning blocked-on-sibling pointer (sibling tickets own deep impl)
* pkg/agentic/pipeline_*_test.go — AX-10 per handler
* tests/cli/pipeline/Taskfile.yaml — CLI smoke coverage
go test could not complete in this sandbox due to wider workspace
go.sum/private-module issues outside this ticket; supervisor catches
in clean workspace.
