[BaraaFatimaZohraLALAGUI]

Stabilized Auto Recognition, added keyboard navigation between boxes, and made shortcuts discoverable from the Recognition result panel.

---

Stability Fixes

• Added requirements.txt with the project dependencies.
• Disabled oneDNN/MKLDNN in both PPStructureV3 instances to avoid the Paddle 3.4.0 ConvertPirAttribute2RuntimeAttribute crash.
• Fixed Auto Recognition closing the app: the new autoRecognitionNotice string was missing from the compiled Qt resources.

---

Auto Recognition Threading

• OCR work now runs in the worker thread, but UI updates and saveFile(mode="Auto") run in the GUI thread via a new resultReady signal.
• Removed the worker's self.exec() call so the thread can finish normally.
• Made cancellation non-blocking: uses requestInterruption(), a _cancelled flag, and no busy-wait loop.
• Keeps references to running workers so they aren't garbage-collected if the dialog closes early.
• Added a progress/notice label and window title to the Auto Recognition dialog.
• Worker exceptions are logged and reported instead of silently killing the app.

Keyboard Navigation

Shortcut	Action
Tab / Shift+Tab	Next / previous detection box
F2 or Enter	Edit the selected box text inline
Esc / Enter	Confirm the edit and return to navigation

Implemented in:

• libs/editinlist.py — new navigateRequested / editRequested signals, inline editor handling, event filter, and focusNextPrevChild.
• libs/canvas.py — new navigation/edit signals and Tab/F2/Enter handling.
• PPOCRLabel.py — navigateShapes(), editCurrentLabelInline(), signal connections, and tooltips.
• libs/utils.py — shortcut hints added to tooltips and keysInfo().

Shortcut Discoverability

• Added an i circle button next to the "Recognition result" dock title.
• Hovering it shows the important shortcuts, clicking it opens the full shortcut list dialog.
• The status bar also shows a short shortcut tip on startup.
