Regenerate the released API contract for 0.25.0

When the test suite runs against this release candidate, test_released_api_contract_fixture_matches_installed_version compares the installed version to tests/fixtures/released_api_contract.json; this bump makes the installed version 0.25.0, but the unchanged fixture still declares v0.24.0, so the release-contract check fails and the frozen public API remains attributed to the prior release. Regenerate and commit the contract fixture for 0.25.0 alongside the version bump.

Regenerate the contract from an ancestor commit

For this bot release candidate, baseline_commit names 1e212024bd931ceb60763bdfbdbed5dfdc3bf6d8, but that commit and the reviewed candidate are siblings with the same parent, so git merge-base --is-ancestor 1e212024 fc6293db fails. The required final release review therefore cannot establish that the snapshot was generated from this candidate's history and must block the release; rerun Release Please/candidate preparation so the recorded source is an ancestor of the resulting snapshot commit.

Include the sandbox hardening fix in the release notes

When sandbox users consult the 0.25.0 notes to decide whether to upgrade, they will not see commit 841dfdd / #5406, which prevents workspace startup files from running during internal workspace operations. Its non-conventional commit subject caused Release Please to omit this security-relevant behavior change from both configured changelog sections, so add an explicit Bug Fixes entry before publishing the release.
