[codex] fix sync skip flags

[scoootscooob]

Summary

Fixes sync option handling so CLI opt-out flags such as --no-transcripts and --no-panels are preserved when sync defaults are applied.

Root cause

parseSyncOptions previously encoded --no-transcripts by setting IncludeTranscripts to false, but syncer.Run later ORed that value with config defaults. When the config default enabled transcripts, the explicit CLI opt-out was overwritten.

Changes

• Add explicit skip fields to sync options for transcripts and panels.
• Apply config defaults only when the corresponding skip flag is not set.
• Add CLI parser coverage for both skip flags.
• Add a desktop-cache regression test proving SkipTranscripts prevents transcript archival even when config defaults enable transcripts.

Validation

• make test
• Manual desktop-cache bulk test with 48 synthetic notes and 144 transcript chunks
• Confirmed sync --source desktop-cache --no-transcripts --no-panels reports transcripts: 0 after the fix

Thanks for the fix. I re-verified this against current openclaw/graincrawl main and found the original branch had gone stale after the org/module-path migration: the new regression test still imported github.com/vincentkoc/graincrawl/..., so GOWORK=off go test ./... failed on the PR as-is.

I landed the same behavior fix via #10 with the OpenClaw import correction and a changelog line. Verification on the replacement PR:

• autoreview helper from openclaw/openclaw: clean, no accepted/actionable findings
• GOWORK=off go mod tidy
• git diff --exit-code -- go.mod go.sum
• GOWORK=off go vet ./...
• GOWORK=off go test ./...
• GOWORK=off go run golang.org/x/vuln/cmd/govulncheck@v1.3.0 ./...

Closing this PR as superseded by #10 / merge commit 51f1a41.
