Rename the simulator and report from pd to blend
The study started as a peering-degree question and grew well past it: propagation,
adversary exposure, deanonymization and time-to-link, reliability under uniform
and correlated churn, messaging redundancy, and cover traffic. The pd name no
longer describes it.

tools/simulators/blend/pd/ -> tools/simulators/blend/, package src/pd -> src/blend,
and reports/blend/pd/ -> reports/blend/. Moved with git mv so history follows.

The text substitutions are deliberately narrow. pd is also the conventional pandas
alias, and pandas genuinely has a pd.plotting submodule, so a blanket pd. -> blend.
rewrite would have corrupted four files. Only package-unambiguous forms were
changed: from pd.X, -m pd.X, pd.<our module>, PD_BYTES_BUDGET, src/pd, and the
pyproject name. All four import pandas as pd lines are untouched and verified.

Both READMEs reframed: peering degree is now presented as the primary axis that
ties the others together rather than as the subject, and the relative links, which
lost a directory level in the move, are corrected.

Verified after the move: ruff clean, 101 tests, 45 verify anchors, make targets,
the script shims, an end-to-end smoke run, and data/report_numbers.py still
reproducing the report tables from the checked-in evidence.

# Messaging-redundancy study: R independent blend cascades per emission (R in 1..4).
# Measures delivery_R (reliability) and deanon_R / full_deanon_R (anonymity cost), and feeds the
# time-to-link / stake-inference figures.
#
# Statistics: 1200 rounds x 8 topology seeds = 9600 rounds per cell -> binomial SEM <= 0.005 on
# every delivery rate, enough to resolve the 1-(1-p)^R law (a coarser grid was non-monotonic in R).
# degree 3 is included because it is the one setting where the responsive sub-graph fragments, so
# it tests whether redundancy can buy back coverage (it cannot -- see the report).
# max_blend_delay=0 keeps it affordable: redundancy multiplies propagation cost by R, and mixing
# delays are not the subject here (the headline delay study is configs/default.yaml).
