Add endless-scrolling TUI table for interactive list commands

[simonfaltum]

Why

Large list commands are hard to use in a terminal today. They print the full result set before users can do anything, which is slow for big lists and makes it hard to browse results. Interactive terminals should get a faster, more navigable experience without changing scripted output.

Changes

Before: list commands drained the full paginated iterator and rendered everything through text templates or JSON.

Now: when the CLI is running interactively (TTY stdin + stdout + stderr, color enabled), list commands with a registered table configuration open a scrollable TUI table that loads more rows on demand. Piped output and --output json keep the existing behavior. Commands without an explicit table config continue to use template rendering.

Implementation:

• Extract shared styles, constants, and helpers from tableview.go into common.go
• Add reusable tableview config, registry, and wrapper types
• Add a Bubble Tea paginated model with fetch-on-demand, cursor navigation, horizontal scrolling, and optional server-side search
• Route interactive list rendering through the TUI when a TableConfig is registered, fall through to templates otherwise
• Integrate with cmdio Tea program lifecycle (acquireTeaProgram/releaseTeaProgram)
• Switch experimental/aitools to the shared static table renderer

Post-review fixes

• Fix UTF-8 backspace corruption in search (byte truncation to proper rune handling via utf8.DecodeLastRuneInString)
• Fix RunPaginated silently dropping model-level fetch errors (now checks FinalModel.Err() like render.go)
• Recompute column widths on every batch, not just the first
• Extract restorePreSearchState to eliminate duplicated search-restore logic
• Show fetch errors in footer while keeping existing rows visible (instead of replacing all data)
• Fix space key not accepted in search input (handle tea.KeySpace in both paginated and non-paginated tables)
• Separate loading and searching concerns: loading is purely "fetch in-flight", searching flag blocks maybeFetch during search input mode (fixes stuck pagination and overlapping fetch races)

Test plan

• go test ./libs/tableview/... ./libs/cmdio/... ./cmd/root/... ./experimental/aitools/cmd/...
• Manual smoke test in a TTY: verify the first page renders immediately and more rows load while scrolling
• Manual smoke test with piped output and --output json: verify existing output is unchanged
• make checks passes
• make lintfull passes (0 issues)

Priority: HIGH — Performance and design concerns in TUI table infrastructure

MAJOR: O(n) re-render on every keystroke

The search/filter functionality appears to re-render the entire table on each keystroke. For large result sets, this will cause noticeable lag. Consider debouncing the search input or using incremental filtering.

MAJOR: Partially-consumed iterator after search

When a user searches/filters, the iterator may have already been partially consumed. If the search is cleared, previously consumed items that didn't match won't be re-fetched. This could lead to confusing behavior where clearing a search shows fewer results than expected.

MEDIUM: Entire feature unreachable until follow-up PRs

This is 1535 lines of new code that is unreachable until the override PRs (#4731, #4732) land. Consider whether the infrastructure could be reviewed more effectively alongside at least one consumer.

What looks good

• Clean separation of concerns between model, view, and update
• Good use of Bubble Tea framework patterns
• Table column configuration is flexible and well-designed
