Give HyperEVM a seven-day market that can take lending offers

[rbcp18]

Why

HyperEVM has exactly one market that trusts LenderCommitmentForwarderAlpha — market 3, created outside this repo — and its payment cycle is thirty days.

For an EMI market that is not just a longer default, it is a floor on how short a loan can be at all. TellerV2 sizes payments through V2Calculations, EMI lands in NumbersLib.pmt, and pmt opens with:

require(loanDuration >= cycleDuration, "PMT: cycle duration < loan duration");

So a seven-day lending offer published into market 3 cannot be drawn. It publishes, sits in the book looking entirely normal, and reverts for every borrower who tries. Teller Pro's on-demand lending writes seven-day terms wherever it can, and HyperEVM is the one chain where it has been forced back to thirty for exactly this reason.

Why a new market rather than a grant

The per-market forwarder slot holds exactly one address. Granting Alpha on market 1 — the seven-day pools market — would not add offers, it would take that market's pools off line. That is the trap Arc hit, and why Base runs offers on 22 and pools on 18.

What this adds

One shortOffers entry in config/chain-bootstrap/hyperevm.ts:

Field	Value
purpose	offers (trusts LenderCommitmentForwarderAlpha, gets no pools)
durationSeconds	7 days
paymentDefaultDuration	5 min, matching market 2's own
bidExpirationTime	24 h, as on Arc's offers market

bootstrap-markets creates Bullet markets on a seconds cycle, so the pmt floor above does not apply to what it makes: one payment at the end, priced off the cycle rather than divided by it. The seven days here is the term we want, not a constraint being worked around.

What does not change

No pools are attached to it, and it stays out of activateMarkets. The hyperRAM entries are untouched.

The file's header and the comment above markets both said every number there describes market 2 as it already is and is never applied. That stays true of long and is not true of the new entry, so both now say which is which — otherwise the next reader takes the new market's numbers for documentation and edits them expecting nothing to happen.

Deploying

Not deployed by this PR. Once merged:

NETWORK=hyperevm BOOTSTRAP_MARKETS=true  # via the chain-deployer service

with CONTRACTS_REF repinned to develop's head. Re-running is safe — anything already in deployments/hyperevm/market-bootstrap.json is skipped, so only the new market is created. The resulting market id then goes into Teller Pro's ODL_OFFER_MARKET_BY_CHAIN as a seven-day Bullet row.
