ctrl-a is consumed as the leader on every press, so it never reaches the
shell and readline's beginning-of-line was gone with no way back — unlike
Ctrl-K, which already has an escape hatch. Fix it the way tmux does:
pressing the leader twice sends the literal leader byte to the focused
pane and clears the pending chord, on both web and TUI, built from the
configured leader so a rebound leader carries it.

Specifies the ctrl-k command bar for both clients: opening and the
leader escape hatch for a literal Ctrl-K, sigils, empty-query recency,
the key model including the session action page, and touch entry.
The match-and-rank algorithm is pinned exactly — normalization, word
boundaries, the per-character score, embedding choice, tie-break — and
closed with twelve fixtures the TypeScript (#146) and Rust (#147)
matchers are both tested against, so their orders cannot drift.
