* feat(tooling): extend strict-ratchet lane to all remaining leaf packages
* fix(packages): burn down indexed-access debt in ai and agent-core
All 196 noUncheckedIndexedAccess errors fixed behavior-identically
(iteration, .at()/slices, DataView byte math, guarded queue peeks) plus
cleanup finds: a sparse-tool diagnostic bug, deduplicated Responses
call/item ID parsing with an honest string|undefined splitter, and a
clearer local failure for redacted-thinking blocks missing signatures.
Removes all 17 remaining non-null assertions across ai, gateway-client,
and llm-core so the assertion ban aligns 1:1 with the ratchet lane.
speech-core joins memory-host-sdk as structurally deferred (imports
src/** via plugin-sdk path mappings).
* feat(tooling): add noUncheckedIndexedAccess strict-ratchet lane
* fix(packages): make indexed access explicit across ratchet packages
Burns down all 65 noUncheckedIndexedAccess errors in the seven ratchet
packages with behavior-identical restructuring (iteration, charAt/slice,
regex-group guards, validated hextet tuple). net-policy invariant
violations now throw instead of failing open. Adds
@openclaw/normalization-core/expect (expectDefined/first/last) with
subpath export and tests. memory-host-sdk fixes kept but the package
stays out of the lane: it re-exports core src/** so the flag would apply
transitively to all of core.
* fix(lint): keep .oxlintrc.json strict-JSON parseable for extension lint wrappers
