* feat(scatter): add bubble variant for three-value comparisons
Bubble chart as a Scatter variant per the issue #62 triage: x and y on
shared zero-based linear scales, bubble AREA proportional to the third
value (r = K*sqrt(size)), one accent bubble, ink-opacity ramp as ink-mass
compensation, largest-first paint order.
scripts/verify-bubble.py derives both axis scales and the area constant
from the set itself (Theil-Sen, leave-one-out) and holds every bound
label and tick against the mark it describes; test-verify-bubble.py
exercises both polarities. Bindings are bubble-specific (data-size,
data-name, data-tick) rather than data-series, so verify-slopegraph.py
never claims a bubble file and neither checker needs scope carve-outs.

* fix(bubble): report a bubble whose peers cannot describe a scale
A bubble holding the only distinct value on an axis was skipped by the
leave-one-out residual test — its own fit is degenerate, and the full-set
fit passes through wherever it was drawn, so a wrong coordinate shipped
clean. Report it as unverifiable instead of skipping it.

* chore: bump to 2.6.3 and register bubble gates
Ridgeline (#143) landed on 2.6.2, colliding with this branch's bump, so
re-bump past it. Also add the bubble gate commands to the maintainer
policy's local_commands, matching what ridgeline registered.

* chore: bump to 2.6.5
The mermaid fix (#131) landed on 2.6.4, colliding with this branch's
bump again. Re-bump past it.
