* fix(extensions): make indexed access explicit across channel plugins
Transport-payload-safe burn-down: malformed Telegram/Discord/QQ/LINE
and sibling channel input keeps existing skip paths; no synthesized
fields, no new throws in delivery loops. Zalo escape sentinels preserve
literal matches instead of undefined replacements.
* fix(extensions): make indexed access explicit across provider and memory plugins
Stream and model iteration, tool-block guards, capture guards, and
sparse accumulators; singleton model reads carry named invariants.
* fix(extensions): make indexed access explicit across tooling plugins, flip the extensions lane
Remaining plugins (oc-path, qa-lab, browser, logbook, and siblings) plus
the tsconfig.extensions.json flag flip. Cleanup: logbook sampleFrames
NaN index at max=1, QA retry clamp at non-positive attempts, dead Canvas
probe and OpenShell no-op slice removed, twitch test setup leak excluded
from the prod lane.
* refactor(plugin-sdk): expose expectDefined via a focused SDK subpath
Extensions imported @openclaw/normalization-core directly, crossing the
external-plugin packaging boundary (it only worked because the runtime
builder bundles undeclared workspace helpers). expect-runtime joins the
canonical entrypoints JSON, generated exports, API baseline, docs, and
subpath contract test; all 78 extension imports now use the SDK seam.
Two scanner-shaped locals renamed for review-bundle hygiene.
* chore(plugin-sdk): raise surface budgets for the expect-runtime subpath
One new entrypoint with one callable export, added intentionally as the
packaging-honest seam for extension invariant helpers.
