Allow users to configure include/exclude glob patterns in
.open-code-review/rule.json (global or project-level) to control
which files are reviewed. Exclude has highest priority, include
penetrates default path exclusions but not the extension allowlist.
Only one layer takes effect following --rule > project > global priority.
Consolidate review rules into a composedResolver that supports four layers
(--rule flag > project .open-code-review/rule.json > global ~/rule.json >
embedded system default), each with first-match-wins fall-through semantics.
When all subtask LLM calls fail (e.g. invalid API key), dispatchSubtasks
now returns an error instead of empty comments with nil error. Partial
failures are recorded as subtask_error warnings so output functions can
distinguish "no issues found" from "review failed".
