Add low-effort slash commands to TUI

[moirahuang]

Description

Stack: 2 of 4. Depends on #13602; followed by #13604.

Adds slash-command effects that the TUI can support without GUI-only panes or orchestration UI: /create-new-project, /export-to-clipboard, /export-to-file, and /cost.

This keeps TUI-specific state transitions local while sharing non-visual behavior with the GUI where practical. Project and review-comment requests go through BlocklistAIController, conversation-file export moves into a shared helper, and /cost validation is shared. Clipboard export uses OSC 52 so text reaches the terminal client's clipboard rather than the headless process host, including tmux passthrough and explicit failure reporting. Successful clipboard and file exports show transient feedback; file feedback includes the destination path and whether an existing file was overwritten.

The PR also includes TUI request and execution plumbing for /pr-comments, but that entry is not currently visible in the local TUI. The GUI has migrated /pr-comments to a bundled skill, while local ./script/run-tui does not yet stage or load bundled skill resources. Fixing local bundled-skill availability is separate follow-up work.

The /compact experience is completed with streamed summary rendering and a dedicated progress label.

In scope

• Expose and execute /create-new-project, /export-to-clipboard, /export-to-file, and /cost in the TUI.
• Add the TUI request and execution plumbing needed by /pr-comments.
• Propagate repository and CWD context needed by repository-aware commands and file export.
• Extract conversation Markdown export policy from GUI input code for reuse by the TUI.
• Export clipboard text through OSC 52, including tmux passthrough and clipboard/PRIMARY targets.
• Show success-colored export confirmation and report clipboard/file failures accurately.
• Share project-creation, review-comment request, and cost-validation behavior with GUI paths.
• Render streamed conversation summaries as collapsible transcript sections.
• Label compaction progress distinctly.
• Add focused coverage for export behavior and feedback, command support, cost validation, OSC 52 encoding, summary rendering, and progress labels.

Out of scope

• GUI-only commands that require settings panes, dialogs, or inline selectors.
• Bundled-skill availability in the local TUI; /pr-comments remains hidden until that infrastructure is available.
• Semantic command IDs or a cross-frontend handler abstraction.
• GUI-style structured argument editing for saved prompts.

How to review

1. Start with app/src/terminal/input/slash_commands/mod.rs and app/src/ai/blocklist/controller.rs for the supported-command boundary and shared non-visual operations.
2. Review app/src/ai/conversation_export.rs alongside the removal from app/src/terminal/input.rs. Confirm filename, CWD fallback, overwrite reporting, and error behavior remain shared policy rather than TUI policy.
3. Review crates/warp_tui/src/terminal_session_view.rs for surface-specific command effects, validation, buffer clearing, export feedback, and telemetry.
4. Review crates/warp_tui/src/clipboard.rs and clipboard_tests.rs for OSC 52 encoding, target selection, flushing, and tmux passthrough.
5. Review crates/warp_tui/src/agent_block.rs, agent_block_sections.rs, and warping_indicator.rs as one compaction-presentation unit.
6. Finish with the focused tests for export destinations, command policy, cost, clipboard transport, summary sections, and progress labels.

Testing

https://www.loom.com/share/a1efde950bd840178af79ccd1d788365

Final-stack validation on 2026-07-11:

• ./script/format — passed.
• cargo clippy --workspace --exclude warp_completer --all-targets --tests -- -D warnings — passed.
• cargo clippy -p warp_completer --all-targets --tests -- -D warnings — passed.
• Added focused regression coverage for conversation export, destination feedback, command support, cost validation, OSC 52 transport, summary sections, and progress labels.

Cargo tests and manual TUI validation were not rerun after the final restack.

• I have manually tested my changes locally with ./script/run

Screenshots / Videos

Not included; manual TUI validation remains outstanding.

Overview

This PR adds TUI support for several low-effort slash commands, shared conversation export logic, native headless clipboard fallback, and TUI rendering for conversation-summary progress.

Concerns

• This changes user-facing headless TUI behavior, but the PR description explicitly says no screenshots/videos were included and manual TUI validation was skipped. Per the repo's TUI review guidance, please attach acceptable TUI visual evidence such as a terminal transcript, render_to_lines/TuiBuffer::to_lines output covering the new slash-command flows, or a ./script/run-tui capture demonstrating the commands end to end.

Overview

This PR adds several low-effort slash command paths to the TUI, extracts shared conversation export behavior, adds a headless native clipboard backend with fallback, and renders conversation-summary progress/sections in the TUI transcript.

Concerns

• This is a user-facing TUI behavior change, but the PR description explicitly says manual TUI validation was skipped and includes no terminal transcript, render_to_lines/TuiBuffer::to_lines snapshot diff, or ./script/run-tui capture. Please include terminal/render evidence demonstrating the new slash commands and summary presentation end to end.
• No approved or repository spec context was available for implementation-vs-spec validation.
• I did not find a diff-line security concern to report in the changed code.
