fix(agent-core): queue cron prompts while goals are paused

Problem

Cron prompts that become due while a goal is paused currently start a full model turn. In a long-running session this repeatedly rereads the complete context even though autonomous goal work is explicitly stopped.

What changed

The cron scheduler now treats a paused goal as temporarily ineligible for delivery. It neither steers the agent nor advances the task cursor, so the prompt remains queued and becomes eligible on the next tick after /goal resume.

The regression test covers both halves of that contract: no steer, telemetry, or cursor advance while paused, followed by one delivery after the goal becomes active. The scheduled-task reference is updated in English and Chinese, and the CLI receives a patch changeset.

Test verification (RED → GREEN)

• RED on upstream main: keeps a due cron queued while the goal is paused failed because one steer occurred instead of zero.
• Revert proof: removing only the scheduler guard reproduced the same RED (1 failed, 20 passed).
• GREEN: the focused file passes 21/21; the complete cron area passes 46/46.
• Changed production lines: 2/2 covered (100% diff coverage).
• Package typecheck and build, changed-file type-aware lint, Sherif, changeset validation, and the VitePress docs build pass.
• Full local suite: 16,846 passed, 12 files skipped by repository configuration, 3 expected failures, 83 skipped tests, and 2 todos. Typecheck, type-aware lint (0 errors), Sherif, changeset status, documentation build, and git diff --check also pass.

Follow-up review fix

Addressed the print-mode hang reported in review: kimi -p no longer keeps a ref’ed interval alive for future cron tasks while the goal is paused, matching the scheduler’s paused-delivery semantics.

• RED: the new regression test failed with expected false to be true when only this CLI guard was absent.
• GREEN: the focused test passes; the complete run-prompt file passes 48/48; the repository suite passes 16,846 tests.
• Independent review: PASS. OpenCodeReview-through-Codex: PASS. Main reread and explicit revert proof: PASS.

Addressed the paused-goal print-mode hang in 54d0bdaee: future cron tasks no longer hold kimi -p open while CronManager is suppressing delivery. Added a regression test with explicit RED (expected false to be true) and GREEN proof. Validation: run-prompt 48/48; full repository suite 16,846 tests passing; typecheck, lint (0 errors), Sherif, changeset, docs build, independent review, OCR/Codex review, and final reread all pass.
