fix(shot): clamp resized capture area to annotations

[dengzhongyuan365-dev]

Clamp screenshot selection resizing by existing annotation bounds.

根据已有标注外接矩形限制截图选区缩放范围。

Log: 修复编辑后缩放选区裁剪标注
PMS: TASK-393987
Influence: 截图编辑后缩小选区时，边界不会越过已有标注外接矩形，避免保存结果裁剪标注内容。

Summary by Sourcery

Keep edited annotations fully included when resizing and saving screenshot selections.

Bug Fixes:

• Prevent resized screenshot selections from crossing existing annotation bounds, avoiding cropped annotations in saved captures.
• Preserve annotation positioning and rendering when resizing selections, including correct capture-region handling in Treeland mode.

Enhancements:

• Improve screenshot editing event handling, cursor behavior, annotation geometry tracking, and selection synchronization across drawing, moving, resizing, rotating, and text editing.

Tests:

• Add coverage for expanding selections around annotations and preserving annotation screen positions during left-side expansion.

Reviewer's Guide

The PR adds end-to-end annotation-aware selection resizing: it derives padded bounds from all visible shape content, enforces those bounds during mouse-driven resizing, preserves annotation screen positions as the selection moves, and applies coordinate-correct annotation compositing when saving cropped screenshots, including Treeland handling.

File-Level Changes

Change	Details	Files
Adds annotation-aware screenshot selection resizing that prevents existing content from being clipped.	Computes annotation bounds, including in-progress and selected/hovered shapes, with drawing safety padding. Constrains all edge and corner resize paths to annotation bounds, minimum sizes, and the capture background. Locks bounds during a resize and translates local annotation coordinates when the selection’s top or left edge moves. Synchronizes the shape widget, toolbar/sidebar, size tips, and repaint state after resizing.	src/main_window.cpp src/main_window.h src/widgets/shapeswidget.cpp src/widgets/shapeswidget.h
Reworks event routing and coordinate handling for edit-mode selection resizing, including Treeland compatibility.	Installs a ShapesWidget event filter and routes relevant mouse events through MainWindow while preserving normal widget events and text-editing behavior. Uses window coordinates consistently for cursor hit testing, drag initiation, resizing, and cursor selection. Avoids Treeland capture-region initialization when an editable ShapesWidget exists.	src/main_window.cpp src/main_window.h
Corrects annotation compositing when saving cropped screenshots.	Calculates the saved image origin and crop intersection against the Treeland source region. Paints annotations with the correct offset and scale relative to the cropped image. Separates content rendering from selection/hover editing controls during image export.	src/main_window.cpp src/widgets/shapeswidget.cpp src/widgets/shapeswidget.h
