feat(core): detect tool validation retry loops and inject stop directive (#3178)
Primary change: prevent the model from burning tokens in an infinite retry
loop when a tool call repeatedly fails schema validation with the same
error (observed with ask_user_question and a malformed `questions`
parameter retrying 10+ times with the same validation error).

- Track consecutive validation failures per (tool name, error message)
  pair in CoreToolScheduler via a `validationRetryCounts` Map.
- After 3 consecutive failures for the same (tool, error) pair, append a
  RETRY LOOP DETECTED directive to the error response instructing the
  model to stop, re-examine the schema, try a fundamentally different
  approach, or surface the issue to the user.
- Reset per-tool counters when the tool invocation succeeds; reset
  globally when an incoming batch shares no tool name with any
  previously failing tool; reset the per-tool counter when the tool
  returns a different validation error so unrelated mistakes do not
  accumulate toward the threshold.
- Distinct from LoopDetectionService, which tracks model-behavior loops
  (repeated thoughts, stagnant actions); this change catches tool-API
  misuse loops at the scheduler layer.

Piggyback fixes bundled in the same PR:

- packages/cli/index.ts, packages/core/src/services/shellExecutionService.ts:
  treat PTY `EAGAIN` on the read path as an expected read error alongside
  `EIO`, avoiding noisy surface-level failures from transient
  non-blocking reads.
- scripts/build.js: switch the settings-schema generation step from
  `npx tsx` to `node --import tsx/esm` for Bun compatibility.

Tests:

- Unit tests in coreToolScheduler.test.ts cover: directive injection on
  the 3rd consecutive failure, counter reset when a different tool is
  called, and counter reset after a successful invocation of the same
  tool (fail → fail → succeed → fail → fail must not trip the directive).
