Herdr now detects CodeWhale agent status — try it from my fork (not merged upstream yet)

[atmosuwiryo]

tl;dr — I added CodeWhale agent support to Herdr, the terminal-based agent runtime. It works on my fork but isn't merged upstream yet — if you use Herdr with CodeWhale you can build it and try it today.

What it adds

Herdr detects what a coding agent in a pane is doing (idle / working / blocked) and reflects it in the sidebar, status indicators, sounds, and OS taskbar progress. This commit makes CodeWhale a first-class agent:

• State detection from OSC signals — CodeWhale drives its window title with a whale + activity verb (🐳 working…, 🐳 reasoning…, 🐳 using tool…, 🐳 verifying…), 🐳 waiting on you… when it needs a decision, and ✓ done / Codewhale at rest, plus OSC 9;4 taskbar progress (busy/clear).
• Screen fallbacks when the terminal doesn't forward OSC titles — the braille-spinner working strip with "Esc to interrupt", the ❯ composer prompt, and the approval band ("Do you want to proceed?" with numbered allow/deny options) are recognized as working / idle / blocked.
• Wiring throughout Herdr — process-name identification, per-agent sound overrides, docs (EN/JA/ZH-CN), and the website agent-detection manifest catalog.

Status

• Working on my fork: atmosuwiryo/herdr @ feat/codewhale-agent
• Not merged upstream yet — the PR was closed unmerged, so it's not in herdrdev/herdr master.

Try it

git clone https://github.com/atmosuwiryo/herdr.git
cd herdr
git checkout feat/codewhale-agent
cargo build --release

then run ./target/release/herdr, spawn CodeWhale in a pane, and the status should show up automatically.

Feedback is very welcome — especially if your CodeWhale version renders the title/status bar or approval prompts differently than the manifest expects.
