feat: leader-based chord keybindings (kitty-style ctrl+w>x) (#143)

* add plan: leader-chord-keybindings

* feat: add chord keybinding parser with ctrl/alt leader validation

Extends parse() to recognize chord bindings like 'ctrl+w>x'. Leader must
be a ctrl+ or alt+ combo; second stage is a single key. Three-stage chords
and empty halves are rejected with a warn. Leader case is normalized
(ctrl+/alt+ lowercased); second-stage case is preserved so ctrl+w>x and
ctrl+w>X stay distinct. Both map and unmap accept chord keys.

* feat: add chord conflict resolution and lazy leader index

Add IsChordLeader/chordPrefixes methods backed by a lazy cache on Keymap,
invalidated on every Bind/Unbind. Add resolveConflicts() at the end of Load()
that drops any standalone binding whose key is also a chord prefix so that
pressing the leader always enters chord-pending state.

* feat: add ResolveChord with layout fallback for chord bindings

* feat: add tests verifying Dump round-trip and KeysFor for chord bindings

Lock in the behavior that chord keys stored as flat strings (ctrl+w>x)
round-trip through Dump/parse and sort alphabetically alongside
single-key bindings via KeysFor and HelpSections.

* feat: extract dispatchAction helper and split pane-nav handlers

Pure refactor preparing for chord dispatch. handleKey's post-Resolve flow
moves into dispatchAction; handleDiffNav and handleTreeNav become thin
wrappers over handleDiffAction and handleTreeAction so keymap-resolved and
chord-resolved paths share the same core.

* feat: add keyState and handleChordSecond for leader-chord dispatch

Introduces keyState sub-struct (chordPending + hint) on Model and the
handleChordSecond method that dispatches resolved chord actions through
dispatchAction, surfaces "Unknown chord" on a miss, and cancels silently
on esc. Wires the chord hint into transientHint() as the lowest-priority
tier so in-flight reload/compact hints still win.

* feat: wire chord-first and chord-second guard... (continued)
