[grade=D] build(rocksdb): bump 8.9.1 -> 10.10.1, version 6.2.3 -> 6.2.4

Per Sami directive 2026-08-02: 'why wouldn't we be using the latest
RocksDB?' Bumped CI to RocksDB 10.10.1 (commit
4595a5e95ae8525c42e172a054435782b3479c57, latest 10.x before 11.x line
began). This is required to read the Hetzner Dropbox bootstrap snapshot's
chain DB — its SST files are at format_version=7, which only RocksDB
>= 10.4.0 can open.

CoDEx flagged a previous proposal of 8.11.4 (wrong: 8.11.x only has
format_version=6 as default; v7 default arrived only in 10.11.0).
CoDEx also flagged an attempted explicit 'table_opts.format_version = 7'
pin as unnecessary — the daemon's own writes can stay at v6 (10.10.1's
default) without breaking the snapshot's v7 SSTs, since mixed v6/v7
SSTs in the same DB are supported. Reverted that pin; documented the
no-pin decision in CHANGELOG.md and inline in txdb-rocksdb.cpp.

src/txdb-rocksdb.cpp: kept RocksDB's own default (6 in 10.10.1) — no
explicit format_version pin. Comment explains why.

scripts/ci/build-rocksdb.sh: rocksdb 8.9.1 -> 10.10.1, commit pin
updated, stale 8.9.1 references in comments cleaned up. Version+commit
pair override is documented; mismatched overrides fail loud (existing
tag-vs-commit SHA check already enforces this).

CHANGELOG.md: v6.2.4 entry. Operator notes for upgrade from 6.2.3 cover:
  - SONAME change librocksdb.so.8.9.1 -> librocksdb.so.10.10.1
  - v7 SSTs from the imported snapshot make RocksDB < 10.4.0 unable to
    open the DB until compaction rewrites them at v6
  - Stale SHA-256 sums in flatpak/scoop/winget will regenerate during
    CI release workflow

packaging/*: 6.2.3 -> 6.2.4 (deb, rpm, docker, flatpak, scoop, winget,
snap, appimage). Stale 8.9.1 references left in workflow comments
(build-all.yml, lint.yml) — out of scope for this commit; they
document Linux CI history, not the build script intent.

src/CMakeLists.txt: 8.9.1 reference in fuzz-target link comment updated
to 'currently librocksdb.so.10.10.1'.

src/clientversion.h: REVISION 3 -> 4 (full version: 6.2.4.0).

CoDEx flagged the downgrade semantics; resolved by deleting the strong
'one-way downgrade' claim from the changelog and replacing it with the
natural-recovery path (let compaction rewrite v7 SSTs at v6).

[grade=D] reflects: package checksums in flatpak/scoop/winget are
intentionally stale until the CI workflow rebuilds them. They MUST
NOT be packaged until regenerated. The changelog explicitly calls
this out; verifier workflow will catch it. CHANGELOG.md notes block
shipping those package manifests.

+## [6.2.4] - 2026-08-02
+
+### Changed
+- **RocksDB bumped 8.9.1 → 10.10.1** in CI (`scripts/ci/build-rocksdb.sh`).
+  Required to read the Hetzner Dropbox bootstrap snapshot's chain DB,
+  whose SST files are at format_version=7. RocksDB 10.10.1 still uses
+  `format_version=6` as its own default; the daemon does NOT pin a
+  different value, so newly written SSTs continue to land at v6. This
+  is deliberate: mixed v6/v7 SST files in the same DB are supported by
+  RocksDB, and v7 writes from this build would close the door on
+  downgrade to 6.2.3 (or any RocksDB < 10.4.0) without fixing anything.
+
+### Notes for operators upgrading from 6.2.3
+- The daemon's runtime dependency is `librocksdb.so.10.10.1`
+  (replacing the previous `librocksdb.so.8.9.1`). Install or build
+  rocksdb from source before rolling 6.2.4 onto a node; the .deb
+  from CI bundles the right SONAME and should just work on
+  Ubuntu 22.04 / 24.04.
+- If you imported the Hetzner Dropbox bootstrap snapshot's chain DB
+  into this node, that DB still contains v7 SSTs. Any daemon down to
+  RocksDB 10.4.0 will read it; RocksDB ≤ 10.3.x will reject the v7
+  SSTs with `Corrupt or unsupported format_version: 7`. After the
+  daemon compacts the imported chain DB, the v7 SSTs may be re-written
+  at v6 and the DB becomes readable by older rocksdb again — that
+  happens naturally as part of normal compaction, no extra action
+  required.
+- Package checksums in `packaging/flatpak`, `packaging/scoop`, and
+  `packaging/winget` are regenerated during the CI release workflow
+  after artifacts are produced; do not ship those package manifests
+  until their SHA-256 sums match the v6.2.4 release artifacts.
