chore: move app skill in-repo + AGENTS.md

- Migrates tactility-app-development from ~/.hermes/skills/ into
  .claude/skills/ for repo co-location
- Adds AGENTS.md with local workstation context, hardware table,
  board-direct build/env wrapper (PYTHONPATH fix), ELF missing-symbol
  triage, app patterns (immersive, QVGA rail, tutorial 2-row,
  GameKit bubbling, screenshot rate-limit), and skill index

+# Deploy & Run on Device (v0.7+ Dashboard)
+
+## Board Discovery (.112 case)
+
+User said "ip ending on 112". Local subnet found via `ifconfig` -> `192.168.68.114/24`, so target is `192.168.68.112`.
+
+Discovery recipe:
+```bash
+arp -a | grep 112
+# ping sweep
+for cand in 192.168.68.112 192.168.1.112 192.168.0.112; do
+  ping -c1 -W 500 $cand
+  curl -m2 -s http://$cand/ | head
+done
+```
+
+Found: port 80 responds with HTTP 302 -> `/dashboard.html`. Port 6666 (old dev port) Connection refused.
+
+## Install Endpoint Change
+
+`tactility.py` (tool v3.5.1) still tries `POST http://<ip>:6666/app/install`. That requires Developer mode enabled on device (Settings > Development > Enable dev server). When disabled, install fails with:
+
+```
+❌ Install request failed: HTTPConnectionPool(host='192.168.68.112', port=6666): ... Connection refused
+```
+
+Firmware v0.7.0-dev Dashboard is on port 80 with new API:
+
+- Discovered via browser devtools / `document.documentElement.innerHTML` JS fetch search:
+  - `GET /api/apps` -> list
+  - `PUT /api/apps/install` multipart field `file`
+  - `POST /api/apps/run?id=<appId>`
+  - `POST /api/apps/uninstall?id=<appId>`
+  - `/api/sysinfo`, `/api/screenshot`, etc.
+
+### Working install via curl / python
+
+```bash
+curl http://192.168.68.112/api/apps | jq
+
+# PUT, not POST
+curl -X PUT http://192.168.68.112/api/apps/install \
+  -F "file=@build/BibleVerse.app;type=application/octet-stream"
+# => 200 ok
+```
+
+Python:
+
+```python
+import requests, pathlib
+ip="192.168.68.112"
+path="build/BibleVerse.app"
+with open(path,'rb') as f:
+    r=requests.put(f"http://{ip}/api/apps/install",
+                   files={'file': ('BibleVerse.app', f, 'application/octet-stream')},
+                   timeout=120)
+    print(r.status_code, r.text[:500])
+# run
+requests.post(f"http://{ip}/api/apps/run?id=one.tactility.bibleverse", timeout=10)
+```
+
+## Platform Arg Required
+
+`tactility.py Apps/MyApp install <ip>` without platform tries all `manifest platforms` (esp32s3,esp32p4) -> fails if only esp32s3 ELF built:
+
+```
+❌ ELF file not built for esp32p4
+```
+
+Fix: always pass platform explicitly matching what you built:
+
+```bash
+tactility.py Apps/BibleVerse install 192.168.68.112 esp32s3
+# or
+tactility.py Apps/BibleVerse build esp32s3,esp32p4 --local-sdk   # build all first
+```
+
+## Browser Verification Recipe
+
+Use Hermes browser tools:
+```js
+// navigate to http://<ip>/dashboard.html -> Apps tab
+document.documentElement.innerHTML.match(/\/api\/apps[^\s"']*/g)
+// returns ["/api/apps", "/api/apps/run?id=", "/api/apps/uninstall?id=", "/api/apps/install"]
+// inline scripts contain:
+function installAppFile(file) { fetch('/api/apps/install', {method:'PUT', body: formData}) }
+```
+
+This avoids guessing old docs.
+
+## Checklist After Install
+
+- [ ] GET /api/apps contains your app id
+- [ ] POST /api/apps/run?id= -> 200 ok (app shows on device)
+- [ ] If install via dashboard UI: drag .app onto upload zone works same as PUT
