tl_gh_issue_close_batch fails on large batches — GraphQL mutation too big

[edimuj]

Problem

tl_gh_issue_close_batch fails when closing 20+ issues at once. The tool builds a single GraphQL mutation with all close + comment operations, which exceeds GitHub's query size limit.

Reproduction

tl_gh_issue_close_batch --repo edimuj/app-chat-game --issues 1214,1213,1212,...(23 total) --reason "not planned" --comment "Closing as stale..."

The generated mutation contains 2 operations per issue (closeIssue + addComment), so 23 issues = 46 mutation fields in one request. GitHub rejects it.

Expected behavior

The tool should chunk large batches into smaller GraphQL mutations (e.g., 10 issues per request) and aggregate results.

Workaround

Fall back to gh issue close in a shell loop:

for issue in 1214 1213 ...; do gh issue close $issue -R owner/repo -r "not planned" -c "comment"; done

Context

Encountered while bulk-closing 23 stale game review findings under an umbrella issue. The first batch partially succeeded (closed ~14 issues) before the error, leaving the operation in an inconsistent state — some issues closed, some not.

Additional requirement: even if chunking isn't implemented, the error response should report which issues succeeded and which failed. Currently the partial success is silent — the caller has to manually check each issue to figure out the state.
