docs(changelog): describe the CW-7550 HTTP 413 retry as it behaves

QA observed the 413 recovery on a local mock (six 640x480 images,
CW/artifacts/qa-20261027/b5/): request 1 was 3,484,230 bytes and got a
413; exactly one retry was sent at 53,212 bytes with 0 images and 6
omission notes (receipt image_projection: cause initial_http_413,
omitted 6, retained 0). Saved images were unchanged. The entry implied
the retry dropped only older images; older-first omission is the
separate local byte-budget path. Wording now matches both paths.

Verified on an export of this commit: sync-changelog.sh --check,
check-feature-release-notes.sh v0.10.2 HEAD and check-versions.sh exit 0.

 - **Tool image validation:** an image returned by a tool must decode before it is sent, so truncated or corrupt files are omitted with a receipt even when they are already within the delivery budget.
 
-- **Image-heavy session recovery:** ordinary image reads use a 256 KiB delivery budget.

+- **Image-heavy session recovery:** ordinary image reads use a 256 KiB delivery budget. Requests measure serialized bytes; over the local budget, older images are omitted from the outbound copy first, with receipts.

 - **Uninstall on every install route:** `codewhale uninstall` previews receipt-owned release files and `--yes` removes only checked files, with the running command last. Both Unix installers and the Windows archive installer record command ownership; self-update renews existing receipts on both. On Windows the running `codewhale.exe` is renamed and deleted once the command exits. Package-managed copies are left alone, and the command prints their exact removal command: npm with its prefix, Cargo with its root, the Homebrew formula, `scoop uninstall codewhale`, `winget uninstall --id HunterBown.CodeWhale`, or the Windows setup's `Uninstall.exe`. Every other `codewhale`/`codew` still on PATH is listed. User data is kept unless you add `--purge-data`, which previews and then deletes only `~/.codewhale` (or a `CODEWHALE_HOME` named `.codewhale`) and `~/.deepseek/snapshots`, refusing symlinks, home ancestors and directories owned by another user. Windows removal is compile-checked but not yet exercised on a Windows host. (Refs #7091)
