feat(input): readline keymap — Esc-clear + Ctrl-A/E/W/K/U (#29)

Browse Source 
Implement the deferred I1b readline shortcuts in the command input
field (ADR-0049, closing issue #29):

  Esc      clear a partly-typed command (only when no completion memo)
  Ctrl-A   cursor to line start (Home alias)
  Ctrl-E   cursor to line end (End alias)
  Ctrl-W   delete the previous word (readline-style, UTF-8 safe)
  Ctrl-K   kill to end of line
  Ctrl-U   kill to start of line

Esc precedence is preserved: a live Tab-completion memo still wins
(Esc undoes the completion first, ADR-0022); Esc clears only when no
memo is alive. While a sidebar panel is focused (Ctrl-O), Esc exits
navigation mode upstream and never clears the input draft. Cursor-only
keys leave history navigation intact like Home/End; buffer-mutating
keys end it like Backspace.

New helpers clear_input / delete_prev_word / kill_to_end /
kill_to_start in src/app.rs. 22 new Tier-1 tests (2458 pass / 0 fail
/ 0 skip, clippy clean). ADR-0049 amends ADR-0046's OOS list;
requirements.md I1b marked done.
