discountry 0ea71503e3 refactor(exchanges): extract ReconnectScheduler from four gateways
standx, ondoperps, lighter and backpack each hand-rolled the same three pieces
around their socket: a 'one pending attempt at a time' timer guard, an attempt
counter feeding a backoff formula, and resetting that counter on open. Four
field-name conventions, four formulas, four places to forget the reset.

ReconnectScheduler owns the timer, the guard and the counter; the backoff stays
a caller-supplied policy (fixed / linear / exponential), since the venues
genuinely want different curves. Verified value-by-value that all four produce
the identical delay sequence they did before.

Scope was chosen, not maximal. The other five gateways' reconnect paths, and all
nine connect/auth/subscribe/heartbeat flows, stay where they are: those are
60-200 lines of per-venue protocol, and folding nine different auth and ping
semantics into one base class would be the wrong abstraction. I also checked the
reconnect paths for the classic defects — aster's timer that looked unclearable
is cleared at the top of connect(), and all three backoff counters do reset on
open — so there was no bug to fix here, only duplication.

12 new tests. 287 pass; tsc and oxlint clean.
