docs: sync ClawRouter v0.12.279 release parity

[JOY (JOY)]

ClawRouter v0.12.279 is the latest stable release observed on 2026-09-22. Advance the documented sync baseline from the already-ported 05de1e0 snapshot to the release commit becb2968711bb203a1498958de27a2b1be3780c3.

The complete delta has 12 files and no changes under upstream src/, packages/, or runtime/. Classify the Desktop UI/statistics, packaging and brand-script changes as outside the standalone Go runtime. Existing Go behavior and previous payment/provider exclusions remain unchanged. The release notes summarize some changes already covered by the prior snapshot; the tracker explicitly avoids counting them twice.

Validation: verified v0.12.278 ancestry and v0.12.279 peeled commit; reviewed the complete file diff; scoped core diff is empty; go test ./..., go vet ./..., go build ./... and git diff --check pass. No deployment or live catalog change.

Code Review

This pull request updates the documentation in README.md and UPSTREAM_SYNC.md to reflect a sync with the upstream v0.12.279 release. The sync log confirms that there are no new Go-applicable core changes in this release, making this a documentation-only update. There are no review comments, and I have no feedback to provide.

Code Review

This pull request updates the documentation in README.md and UPSTREAM_SYNC.md to reflect the synchronization with the upstream v0.12.279 release, noting that no new Go-applicable core changes were introduced. Feedback is provided to improve the phrasing in the sync log by changing 'no new port' to 'no new porting' for better readability.

[gemini-code-assist]

The phrase 'no new port' is grammatically awkward in this context. Using 'no new porting' is more natural and grammatically correct.

Validation disposition: the wording suggestion for no new port is non-actionable. Port is used as a noun for a Go adaptation throughout this tracker; the sentence accurately states that this release requires none. No behavioral or factual change is needed. Gemini reviewed head 1e51899; CodeRabbit completed and all CI/security checks passed on that head.
