…verts Rename VaultToken -> DepositToken (on-chain ERC20 name/symbol unchanged) so Vault.token()'s generated hook no longer collides with the token contract's own base hook, eliminating the need for a custom getHookName policy in wagmi.config.ts. Re-deployed and re-pinned DepositToken/Vault addresses. Also tighten the three inverted revert tests (Vault, OwnedRegistry, SixDecimalToken) to assert the specific revert error instead of a bare vm.expectRevert(), so a scenario silently turning into a different bug would be caught.

Adds a
/bugsroute group with deliberately broken pages, each backed by a realcontract on anvil. Purpose: demo an agent connected to ethui over MCP diagnosing
failures from live chain state — not from reading source.
Governing constraint: no scenario is diagnosable from source alone. Where the bug
does live in source (decimals, allowance), the code reads as idiomatic and a
competing explanation exists that only on-chain state rules out.
