feat: prune a conversation from the TUI with Ctrl+R#16
Merged
Conversation
Adds a per-conversation prune action mirroring the Ctrl+D delete flow: Ctrl+R on the selected row opens a confirm prompt showing its size, and on confirm prunes that one file in place (dropping toolUseResult + file-history-snapshot via the shared pruneFile) and refreshes the SIZE column. The conversation stays in the list, just smaller. This is the TUI half of the prune feature; the `ccs prune` CLI is the batch half.

Adds a per-conversation prune action mirroring the Ctrl+D delete flow. Ctrl+R on the selected row measures the projected saving and opens a confirm prompt - "Prune "<topic>"? 75MB -> 53MB, saves 21MB (keeps dialogue). [y/N]" - and on confirm prunes that one file in place via the shared pruneFile (drops toolUseResult + file-history-snapshot, integrity-checked atomic replace) and refreshes the SIZE column. The conversation stays in the list, just smaller. Lands on main directly: the original #16 was stacked on the CLI-prune branch and merged into that branch instead of main, so the Ctrl+R binding never reached main.

The TUI half of the prune feature: a per-conversation prune action, mirroring the Ctrl+D delete flow.
Prune "<topic>" (75MB)? Removes duplicate data, keeps dialogue. [y/N]pruneFile(dropstoolUseResult+file-history-snapshot, integrity-checked atomic replace), and refreshes the SIZE column in place. The conversation stays in the list, just smaller.--helpkeybindings updated.This is the clean way to prune (and then resume-test) a single low-risk conversation, vs the batch
ccs pruneCLI.Stacked on #14
Based on
feat/prune-cli(#14) since it reusespruneFile. Targets that branch so the diff is just the TUI action; it'll retarget tomainonce #14 merges (and I'll rebase over the responsive-width changes from #15).Tests
TestPruneConversationShrinksAndUpdatesSize- prunes a temp conversation, asserts the file shrinks, the snapshot is gone, the message is kept, and the displayed size (in bothitemsandfiltered) updates.TestCtrlREntersAndCancelsPruneConfirm- Ctrl+R enters confirm mode, Esc cancels.go test -cover= 64.1%.Note
Pruning runs synchronously on confirm (like Ctrl+D delete), so a multi-GB file briefly blocks the UI. Acceptable for a confirmed one-off; async with a spinner is a possible later polish.
