kshitij 1a02e8a793 fix(agent): preserve destroyed tool-call argument bytes in the WARNING log
Review follow-up (W1): the pre-send transcript sanitizer
(agent_runtime_helpers.sanitize_tool_call_arguments) runs on the
PERSISTED messages list before every api_messages build and rewrites any
json.loads-failing argument string to "{}" in the transcript, prepending
a corruption marker to the paired tool result. That in-transcript repair
is deliberate (the stored turn must be replayable next call), but it
destroys the model's original bytes — for a truncated write_file call
those bytes are the user's streamed file content (#80498), and they
previously survived only as an 80-char log preview.

Until a sidecar-preservation design exists, make the bytes recoverable:
both destruction sites (the transcript sanitizer's WARNING and
_repair_tool_call_arguments' unrepairable-path WARNING) now log the full
original argument string bounded at 100KB instead of 80 chars. Corrupted
calls are rare; an oversized WARNING is a fair price for the only copy
of real user content.
