epic: core file operations #87

Summary

Deliver safe rename, Recycle Bin delete, copy, cut, paste, move and conflict handling on a shared operation engine, then retry, history, pause and undo/redo.

Motivation

Core file management is the main gap between ControlFS and a usable file manager (and DeckCrate's feature set).

Scope (in recommended order)

• feat: add a shared file operation engine (plan, progress, per-item results) #10 — feat: add a shared file operation engine (plan, progress, per-item results) (priority: critical)
• feat: rename files and folders with extension-preserving selection #11 — feat: rename files and folders with extension-preserving selection (priority: critical)
• feat: delete to the Windows Recycle Bin with explicit permanent-delete fallback #12 — feat: delete to the Windows Recycle Bin with explicit permanent-delete fallback (priority: critical)
• feat: copy files and folders #13 — feat: copy files and folders (priority: critical)
• feat: move files and folders (same-volume rename, cross-volume copy then delete) #14 — feat: move files and folders (same-volume rename, cross-volume copy then delete) (priority: critical)
• enhancement: generalize conflict resolution to every file operation #17 — enhancement: generalize conflict resolution to every file operation (priority: critical)
• feat: add cut to an internal controller clipboard #15 — feat: add cut to an internal controller clipboard (priority: critical)
• feat: paste clipboard items into the current folder #16 — feat: paste clipboard items into the current folder (priority: critical)
• enhancement: add Select all and Clear selection actions #23 — enhancement: add Select all and Clear selection actions (priority: medium)
• feat: retry a failed operation #18 — feat: retry a failed operation (priority: high)
• feat: retry only the failed items of an operation #19 — feat: retry only the failed items of an operation (priority: high)
• feat: add operation history #20 — feat: add operation history (priority: high)
• feat: pause and resume running file operations #21 — feat: pause and resume running file operations (priority: medium)
• feat: undo and redo reversible file operations #22 — feat: undo and redo reversible file operations (priority: medium)

Dependencies

• feat: add a shared file operation engine (plan, progress, per-item results) #10 → feat: copy files and folders #13, feat: move files and folders (same-volume rename, cross-volume copy then delete) #14, feat: delete to the Windows Recycle Bin with explicit permanent-delete fallback #12, enhancement: generalize conflict resolution to every file operation #17, feat: retry a failed operation #18, feat: add operation history #20, feat: pause and resume running file operations #21
• feat: move files and folders (same-volume rename, cross-volume copy then delete) #14 → feat: add cut to an internal controller clipboard #15 → feat: paste clipboard items into the current folder #16 (feat: paste clipboard items into the current folder #16 also needs feat: copy files and folders #13)
• feat: add operation history #20 → feat: undo and redo reversible file operations #22 (feat: undo and redo reversible file operations #22 also needs feat: rename files and folders with extension-preserving selection #11, feat: delete to the Windows Recycle Bin with explicit permanent-delete fallback #12, feat: copy files and folders #13, feat: move files and folders (same-volume rename, cross-volume copy then delete) #14)
• feat: retry a failed operation #18 → feat: retry only the failed items of an operation #19

Acceptance Criteria

• Every issue in the scope is closed or explicitly moved out of the milestone with a reason.
• PROGRESS.md, both changelogs and the relevant docs reflect what shipped.

Tracking issue for milestone 1 · Core File Operations. Priority: high (all critical items are done: #10–#17 via #101–#104; remaining scope is high/medium).
