rtk ls silently dropped content: no display cap on large listings, noise-filtered dirs vanished without a trace, and dotfiles were shown by default via a forced -a.

Now:

• Listings are capped; everything RTK hides (overflow + filtered noise) is recoverable with a single tee tail command that returns only unseen content.
• Dotfiles follow standard ls behavior, shown only when -a is passed.
• The TTY-only summary footer is removed; agents never saw it.

Tested current head (67a3576). Two real bugs confirmed locally, two cleanup points.

1. -A silently drops dot-prefixed noise dirs with zero trace (ls.rs:303)

mkdir -p .git node_modules && touch README.md
/bin/ls -A .        # → .git  node_modules  README.md
rtk ls -A .         # → README.md, "1 filtered" (node_modules only)

The teed recovery file (the one the "N filtered" hint points to) only contains node_modules/ — .git isn't in the listing, isn't counted in "filtered", and isn't in the recovery file. It's just gone. show_all detection (a.contains('a')) doesn't recognize uppercase -A, and the flag isn't stripped before forwarding to the real ls, so the child actually runs with -A (dotfiles included) while rtk's own noise filter still assumes show_all == false and drops them — the exact "filtered dir vanishes without a trace" bug this PR is meant to fix.

2. Tracking label hardcodes -la even when -a wasn't passed

rtk ls .   # no -a flag at all

rtk gain --history records this as rtk ls -la . regardless — the label at line 87 is a fixed string, not built from the actual flags used. Misrepresents what was actually run.

Two smaller cleanup points, not bugs:

• Same concept named 3 different ways across the file: hidden (the Vec in compact_ls), 'filtered' (its own doc comment), noise (in run()), filtered again (as hidden_hint's param name).
• hidden_hint() hand-rolls its own two-category overflow text instead of extending the existing shared join_with_overflow helper (core/utils.rs:151).

Verified locally (merged onto #3798 since develop itself doesn't compile): fmt/clippy clean, 2975 tests pass (+10 new). Smoke-tested the binary: dotfiles now hidden by default and shown with -a, filtered noise dirs produce the ... (N filtered) note plus a one-shot tee tail command containing only the dropped entries — recovery works as advertised. Good call removing the TTY-only summary agents never saw, and recording unparsable lines as hidden instead of silently dropping them. LGTM — merge after #3798.
