Re-generate v6.6 changelog

[cursor]

PR Summary

Low Risk
Documentation-only change to CHANGELOG.md with no runtime or behavioral impact.

Overview
Updates the v6.6 CHANGELOG.md section by inserting five new sei-chain bullets at the top of the release list (newest first), ahead of the existing State Store compact-prune entry.

The added lines document recent backports and release prep work: legacy cosmos_only SC write mode (#3717), RPC hash race fix (#3697), GoReleaser static seid binaries (#3694), version bump to v6.6.0-rc1 (#3688), and the prior changelog update for 6.6 RC1 (#3686). No application, RPC, or state-machine code is modified in this PR—only release notes.

LGTM — changelog-only update for v6.6 rc2 prep.

Extended reasoning...

Overview

This PR only modifies CHANGELOG.md, adding five entries to the top of the v6.6 section documenting recent backports (#3717, #3697, #3694, #3688, #3686) in preparation for cutting rc2. No runtime code, configuration, or build files are touched.

Security risks

None. This is a documentation-only change with no impact on binaries, state, or execution paths.

Level of scrutiny

Minimal. Changelog updates are mechanical release-prep hygiene — the entries correctly reference existing merged PRs, are formatted consistently with the surrounding list, and are ordered newest-first as the rest of the file is.

Other factors

The bug hunting system found no issues, and the diff is trivially verifiable against the linked PR numbers. Safe to approve without human review.

Documentation-only PR that regenerates the v6.6 changelog for RC2, adding five backport/version-bump entries. The change is correct and safe to merge.

Findings: 0 blocking | 2 non-blocking | 0 posted inline

Blockers

• None at the file/PR level.

Non-blocking

• Codex flagged the v6.6 changelog as incomplete, listing ~14 PRs (e.g. #3728, #3722, #3729, #3715, #3705, #3689) as missing. I verified each: none carry the backport label or a Backport release/v6.6 title — they are ordinary main PRs, not v6.6 backports, so their exclusion is correct. This is a false positive; no action needed.
• Cursor's second-opinion review (cursor-review.md) was empty — that pass produced no output.
