feat(core): show a performance report at the end of every run (#36077)

After a run, Nx prints the cached-task summary but gives no insight into
how the
run's wall-clock time was spent or how to make it faster — no breakdown
of the
critical-path floor versus parallelism contention, and no actionable
guidance.Expected Behavior
Every run ends with a concise performance report:
- Headline stats — run duration, cache result (hit rate, or
Skipped (--skip-nx-cache)), critical path (the dependency floor: how long the
run
would take with unlimited slots), and recoverable time (wall-clock lost
to slot
contention — recoverable with a higher--parallelor more machines). - Targeted recommendations, one per lever and ordered
cheapest-action-first:
speed up/split the longest critical-path tasks (listed inline), raise
--parallel, distribute with Nx Agents, enable remote cache, or drop
--skip-nx-cache. Only the levers that actually apply to the run are
shown. - A docs link — a clickable OSC 8 hyperlink where supported, a plain
auto-linked URL in CI, carrying autm=performance-reporttag. - Where it renders — in the Terminal UI, inside the exit-countdown
popup
(pressingqmid-run still shows the original exit dialog); otherwise
(non-TUI,
or a single task) it's flushed to the terminal after the run summary.
The report
is delivered exactly once.

Notes
- The analysis (
PerformanceAnalysis) is a pure function of the
timings the
lifecycle collects — no coupling to the orchestrator/scheduler. It
derives the
occupancy timeline, the critical path, and the overhead split entirely
from task
start/end timestamps. - The report is built once at the end and delivered either through the
native TUI
exit popup or a terminal flush, deduped so it never prints twice.
