version bump

getCommitRangeDiff and getLatestCommitDiff had maxBuffer set to 1MB.
When a task produced a larger diff (common for 10+ minute tasks),
execSync threw, the catch block returned null, and the review loop
broke immediately with no message — reviews were silently skipped for
larger tasks while smaller tasks reviewed fine.

- Increase maxBuffer to 10MB in both functions (the review prompt
  builder already truncates to MAX_DIFF_BYTES = 50KB before sending
  to the model, so the full diff in memory is fine)
- Add a diagnostic sendChatMessage when the review loop is skipped
  (baseRef undefined or no diff), so silent skips are visible

+#### Auto-review and Auto-commit
+
+At loop startup the review question is asked FIRST. When `autoReview` is
+enabled, commit is **mandated** — after task execution, changes are
+committed (via a commit agent session when the task agent didn't
+self-commit), then the complete task diff (`baseRef..HEAD`) is reviewed
+against the task description. On a `fail` verdict the task is
+re-executed with the review feedback injected into the prompt (looping
+until the review passes or `maxReviewRetries` is exhausted). After
+re-execution, changes are committed again and the full diff is
+re-reviewed with the same base ref so the reviewer sees the complete
+state — original work plus fixes. On pass, the changes are already
+committed and the worktree merges.
+
+When `autoReview` is disabled, `autoCommit` runs a follow-up commit
+agent after each task with no review. Both options can be overridden at
+loop startup via a selection prompt (config YAML values are honored
+without prompting when set explicitly).
+
+`commitModel` and `reviewModel` accept `<provider>/<model>` strings (e.g.
+`anthropic/claude-sonnet-4`) resolved via the model registry. When empty, the
+task's model is inherited. `implModel` sets the model for task implementation
+in sequential mode (overridden by `execution.models` round-robin in parallel
+mode).
