* fix: cap consecutive tool validation failures to prevent stuck-loop (#2783)
When the LLM repeatedly emits tool calls with arguments that fail schema
validation, the agent loop retries indefinitely — each failed validation
returns an error tool result, the LLM retries with the same broken args,
and the cycle burns budget with no progress.
Add a consecutive-failure counter in runLoop that tracks turns where ALL
tool calls fail. After MAX_CONSECUTIVE_VALIDATION_FAILURES (3) consecutive
all-error turns, the loop emits a diagnostic stop message and terminates
cleanly. The counter resets whenever any tool call in a turn succeeds, so
intermittent failures do not trigger early termination.
Closes#2783

* chore: retrigger CI
* fix(test): repair agent-loop.test.ts — close unclosed blocks, merge imports
Two test suites were concatenated without closing the first suite's
it+describe blocks, placing the second suite's imports inside a function
body and triggering 'Unexpected "{" ' from esbuild. Merged into a single
well-structured file with consolidated imports and proper closings.
