feat(cli): add an interactive table renderer

[Chase J (chajac)]

Overview of Changes

Interactive flow lists need a renderer that can filter rows and handle terminal changes. This change adds text search, row navigation, and a view that fits the terminal. It redraws after a resize and restores the previous screen when the view closes.

Base: chajac/list-printed-layouts.

Testing

Naming, lint, format, type, unused-code, and build checks passed. The full test suite passed: 2,550 tests, no failures.

bash scripts/check-naming.sh
bun run typecheck
bun run lint --max-warnings 0
bun run format:check
bun run knip
bun run test
bun run build

Tests cover cleanup after setup errors, frame bounds, search, navigation, resize, Enter, Esc, small terminals, Unicode, control characters, cleanup, and visible-row formatting. Node 24 stream probes also checked input handling and cleanup.

Checklist

• Changes follow the code style of this project
• Self-review completed
• Tests added/updated (or not applicable)
• No breaking changes (or described below)

Walkthrough

Adds an interactive human-mode filter list with searchable items, alternate-screen rendering, debounced resize handling, cancellation, and filtered results. Adds responsive frame rendering with scrolling, highlighting, status states, ANSI-aware clipping, and terminal text sanitization. Adds display helpers, public filter-list types, terminal lifecycle utilities, tests, and the @clack/core dependency.

Merge Risk: 🔵 Low · up to 95424

The new interactive filter-list renderer is otherwise well covered by tests and prior review passes found no defects in the display, resize, or alt-screen lifecycle utilities. Two small gaps remain: a rare setup failure could leave a terminal resize listener attached, and one test could pass without verifying that a frame was actually drawn on the alternate screen. Neither blocks everyday use, but both are worth fixing before merge for cleanliness and test confidence.

In `@src/shell/ui/renderers/filterList.test.ts`:
- Around line 35-36: Update the test assertions around enterAltScreen and
leaveAltScreen so both frameStart and "alpha" are verified to occur within that
alternate-screen interval; avoid assertions that can pass when frameStart is
absent or when "alpha" only appears in final normal-screen output.

In `@src/shell/ui/renderers/filterList.ts`:
- Around line 29-32: Update the setup flow around withDebouncedResize so every
operation after terminal creation is enclosed by an outer try/finally that
always calls terminal.dispose(), including when createSearchIndex invokes
args.searchText and it throws. Preserve screen.close() in its existing
idempotent inner cleanup path.
