* fix(plan-comments): restore embedded inline comment widgets in Plan view
Reinstate CodeMirror block-widget comments so plan annotations stay anchored to selected lines and preserve drag/selection behavior without floating overlays.
* fix(file-comments): return Files editor comments to embedded widgets
Use inline block widgets for file drafts while keeping full-path draft scoping, so similarly named files no longer risk comment collisions.
* fix(diff-comments): render inline comments through annotation portals
Replace absolute floating positioning with annotation-target portals to keep diff comments attached to their lines across shadow DOM updates.
* chore(comments): remove deprecated floating comment hook
Drop the unused floating-comment implementation now that plan, file, and diff views all use embedded comment rendering paths.
* fix(codemirror): expose gutter width as CSS variable
Measure the current CodeMirror gutter and publish --oc-editor-gutter-width on the editor host so inline widgets can size to the visible code area without hardcoded dimensions.
* fix(context-panel): publish panel width for embedded widgets
Set --oc-context-panel-width on the context panel in both docked and expanded modes so comment widgets can follow the active panel width dynamically.
* fix(file-comments): constrain inline input to editor content width
Use context-panel and editor-gutter CSS variables to cap comment input width to the visible editor content area, keeping action buttons fully visible in no-wrap mode.
* fix(file-comments): constrain inline comment cards to content area
Apply the same variable-based width cap to saved comment cards so card actions stay visible when long lines force horizontal scrolling.
* fix(diff-comments): stabilize new comment annotation identity
Derive new-comment annotation ids from selection side and line range, and reuse that id for portal target lookup and keys to avoid remount glitches.
