feat: default Skip slippage tolerance of 0.1%

[Kefancao]

What

Sets an explicit default slippage tolerance of 0.1% on all Skip route execution, replacing the Skip API's implicit server-side 1% default (and the Noble sweep's hardcoded '1').

• DEFAULT_SKIP_SLIPPAGE_TOLERANCE_PERCENT = '0.1' in constants/skip.ts (Skip's slippageTolerancePercent is percent units).
• Injected once in the skipClient wrapper (executeRoute / messages / messagesDirect), spread before the caller's request so per-call values still override. Deposits (including the updatedSkipClient signer path), withdrawals, swaps, and the Noble sweep all execute through these, so one injection point covers everything — this also resolves the TODO(deposit2.0): add custom slippage tolerance here in depositHooks.ts.
• Noble balance sweep's hardcoded '1' now uses the shared constant.

Behavior notes for review

• This is a real tightening (1% → 0.1%) on execution: routes with swap legs (EVM swaps, Osmosis venue) will fail rather than fill if price moves >0.1% mid-execution. Stable-to-stable bridge routes are effectively unaffected.
• The Noble sweep is an unattended background job; pure USDC IBC legs don't exercise tolerance, but flag if you'd rather keep it at 1% for robustness — it's one hunk.
• route() quote requests are untouched (the SDK's RouteRequest takes no tolerance; it's execution-scoped via BaseSettings).

Testing

tsc --noEmit clean. No unit tests cover the wrapper defaults today; happy to add one if there's a preferred harness for hook wrappers.
