fix: add positive idle detection for kiro-cli prompt

[smileynet]

Summary

• Kiro's idle prompt is now positively detected (instead of falling back to a generic heuristic)
• not guards prevent false idle when working indicators are in the same screen region
• Regression tests cover idle, working, overlap, stale scrollback, and blocked precedence

Root cause

Currently there is no positive confirmation for idle state in the kiro manifest, only a fallback rule that is susceptible to false negatives due to text in scrollback.

Evidence

Captured via herdr agent read <pane> --source detection --format text against kiro-cli 2.13.x on Windows. Verified with herdr agent explain <pane> --json.

State transitions confirmed through the local-override hot-reload loop: idle → working → blocked → idle. No false positives from stale scrollback, short terminals, or narrow panes.

Idle:

\\ ext
ask a question or describe a task ↵
/copy to clipboard
\\

Working:

\\ ext
Kiro is working · Type to steer · Ctrl+S to queue
\\

Design

• Priority 200 overrides stale working text in scrollback.
• Region 5 handles line wrapping in narrow panes.
• not guards prevent false idle when positive working indicators are in the same region.

Validation

• cargo test --bin herdr kiro (9 passed)
• Live pane verification via the local-override hot-reload loop
• State transitions confirmed: idle → working → blocked → idle

Notes

• website/agent-detection/kiro.toml synced with src/detect/manifests/kiro.toml in this PR.
• Discussion Kiro CLI: idle detection rules + integration proposal #982 proposed matching the ▸ prompt character via regex. This rule matches footer text instead to avoid false positives from ▸ appearing in output.

📝 Walkthrough

Walkthrough

This PR adds a new prompt_idle detection rule to the Kiro manifest in both src/detect/manifests/kiro.toml and website/agent-detection/kiro.toml, bumps manifest versions and timestamps, and adds a test verifying idle, working, and blocked state precedence.

Changes

Kiro Prompt Idle Detection

Layer / File(s)	Summary
prompt_idle rule and manifest version updates src/detect/manifests/kiro.toml, website/agent-detection/kiro.toml	Both manifest files get a new prompt_idle rule that marks Kiro idle when prompt/clipboard text appears near the bottom of recent output, unless working or cancellation markers are present. Manifest version and updated_at timestamp change from the June 2026 release to 2026.08.01.1.
Test coverage for idle/working/blocked precedence src/detect/manifest/tests.rs	A new test verifies Kiro idle footer detection, working markers and spinners, and precedence rules for overlapping or stale idle/working evidence, and approval-dialog blocking precedence.

Greptile Summary

The PR adds positive Kiro idle-prompt detection while preserving working and blocked precedence.

• Adds a priority-200 idle rule based on the prompt and clipboard footer.
• Vetoes idle detection when live working indicators overlap the footer region.
• Synchronizes the bundled and website manifests with a version bump.
• Adds regression coverage for idle, working, overlap, stale scrollback, and blocked states.

Confidence Score: 5/5

The PR appears safe to merge with no actionable correctness or security issues identified.

The synchronized manifests satisfy the repository’s update contract, and the new tests cover the rule’s idle, working, overlap, stale-scrollback, and blocked-state behavior.

Important Files Changed

Filename	Overview
src/detect/manifests/kiro.toml	Adds a versioned positive idle rule whose priority and localized vetoes preserve blocked and live-working precedence.
website/agent-detection/kiro.toml	Keeps the remotely published Kiro manifest byte-aligned with the bundled manifest and its bumped version.
src/detect/manifest/tests.rs	Adds focused regression cases covering the new rule and its principal precedence interactions.

@smileynet could you remove tests? i'm slowly trying to remove integration tests as they do not have meaningful purpose for fast changing patterns
