Ship Theseus 0.3.31 32c4abea (screenshot white-loop fix + Aegis IPC + light-mode surfaces)

Setup    32c4abea9f2f15bb319e355b2cda747fc7d25eac350f7b9512b92894bae97c30
Portable 47af67894b389174f034dd15a2d2c99605bfcb941fccd084242fc0c52cc6e90a

Fixes since 0.3.28 (all riding this ship since 0.3.29/0.3.30 site
files never reached LIVE):

a279864 - Root cause of the "screenshot is still blank white"
symptom: captureTab reads activeTab(). After the first capture the
editor tab BECOMES active, so every subsequent shot snapshotted the
editor's own still-blank canvas — that white PNG got written to
scratch, fed into a new editor, and the next re-capture snapshotted
THAT. A self-referential feedback loop. captureTab now skips
add-on-owned and Settings tabs, falling back to the last real page
tab tracked in setActive(); if none exists, a clear "open a page
you'd like to shoot first" error rather than white pixels.

4c55f04 - Aegis card in Settings > General crashed on load because
the IPC handlers used a different response shape than the UI
expected. Reads corrected on both sides.

df10884 - Aegis retires the legacy bchwallet folder on every launch,
and Aegis gets a branded dock/list icon.

1574545 - Every dark-hardcoded surface in Settings light mode (.polrow
collision-policy rows, .segseg, .engcat, .ctxmenu, select/input
backgrounds) now maps to a BCH-palette equivalent — no more solid
dark blobs on the white page.

ea9bcab / 4ed55b7 - Site release-notes text updated to include the
per-add-on diagnostic report already in the 0.3.28 build.

Deployed. Verified LIVE 0.3.31.
