 * computeStallInfo/computeRenderStallInfo signal computation stays
 * renderer-local, each renderer has its own stream-metrics shape to derive
 * a WaitingState from).
 *
 * The split this hoists is a DATA/pure-function contract: a renderer decides
 * WHICH state it is in (from its own approval/stall/reconnect signals, in the
 * TUI's precedence order, approval beats reconnect beats pre-first-token
 * beats stalled beats thinking) and calls waitingPhrase(state, ctx) for the
 * exact wording. Neither renderer should carry its own copy of these five
 * strings/rotation, that duplication is exactly what the renderer/input parity audit found
 * (the agent's ui-factory.ts:308-313 was rotating-only, with no honest
 * stall/reconnect/approval split at all).
 *
 * PURE, no fs, no terminal I/O, no timers. Gradient color, spinner glyph,

 *  - 'reconnecting'    , the transport is retrying after a drop.
 *  - 'pre-first-token' , no delta yet this turn; normal for reasoning models
 *                          that think before emitting (NOT "stalled", that
 *                          would wrongly blame the provider for ordinary
 *                          pre-token latency).
 *  - 'stalled'         , silence AFTER the stream had already started
 *                          producing tokens.
 *  - 'thinking'        , the ordinary case: tokens are flowing at a normal
 *                          cadence, show a rotating whimsical phrase.
