Three coupled fixes that together stop frustrated sessions from being
mislabelled as `power_user_path` and make click timelines actually
diagnosable.
1) Counter propagation (compress.ts, compress-sessions.ts):
compress now returns rageClickCount / network5xxCount / network4xxCount
and writes them back to SessionMeta. Previously these stayed at 0
forever because PostHog recording metadata doesn't expose them and
nothing updated the row after compress ran.
2) Tag rule hardening (tagger.ts, compress-sessions.ts):
- power_user_path v1 fallback now requires rageClickCount===0; without
this guard any auth user with 20+ clicks (rage clusters included)
was labelled a power user.
- New frustrated_session tag (rageClickCount>=3, P2) for sustained
friction beyond a single cluster.
- compress-sessions re-runs tagSession+scoreSession after writing the
fresh counters, so the corrected tags land on the row.
3) Click target enrichment (compress.ts):
describeTarget used to read tagName/attributes off MouseInteraction
events — fields that don't exist on rrweb type=3 source=2 — so every
click rendered as `[el]`. Now compress builds a node map from
FullSnapshot (type=2) and keeps it in sync with mutations
(type=3 source=0), then resolves clicks via `d.id`. Clicks now show
real tag + visible text / aria-label / name / data-testid.
