feat[oz-retainer-07]: emit bond and liveness update events

[md0x]

Audit remediation feature

Managed OO requester-set bond and custom liveness changes currently mutate request settings without oracle-side events. This additional Retainer 07 feature makes those changes observable while preserving the request-manager override behavior.

This PR is built on #56, which provides the event pattern and optimizer setting required for the available EIP-170 margin.

References: FRO-109 · audited scope tag

Resolution

• Add BondUpdated and CustomLivenessUpdated with the concrete request tuple and old/new values.
• Emit each event after the requester-controlled setting is updated.
• Cover initial defaults, subsequent updates, lifecycle restrictions, and request-manager override precedence.
• Document how consumers combine requester events with request-manager override events to derive effective proposal settings.

Validation

• forge test --match-contract 'ManagedOptimisticOracleV2Test|DeferredPayoutTest' — 74 tests passed
• Polygon fork suites — 15 tests passed
• cd pm-v2-oo-reporter && forge test --match-path test/OOReporter.t.sol — 45 tests passed
• forge build --sizes — ManagedOptimisticOracleV2 24,469 B (107 B margin)
• cd pm-v2-oo-reporter && forge fmt --check
• git diff --check

Reviewed FRO-109 at this exact head. The new events, emission timing, initial/subsequent values, lifecycle restrictions, request-manager precedence, ABI compatibility, coverage, and consumer documentation are correct.

This approval is for #58’s intrinsic diff. Do not merge it while parent PR #56 has requested changes; once #56 is accepted, rebase/retarget #58 and revalidate the final contract sizes because the reported Managed OO margin is only 107 bytes.

thanks, we indeed should have added these when porting to this repo!
