Auto upgrade 0.6.7 to 0.7.0

Apply the mechanical parts of the Open Mercato 0.6.7 → 0.7.0 upgrade to a downstream app. Treat the matching section of UPGRADE_NOTES.md as the source of truth and leave every intent-sensitive change as an explicit manual finding.

Scope

Operate on a standalone app or downstream repository that depends on @open-mercato/*. Never modify the framework monorepo, framework-owned packages/, dependency pins, lockfiles, generated output, vendored dependencies, or secrets. Run after the user has selected and installed 0.7.0.

Arguments

• --path <dir>: downstream repository root; defaults to the current directory.
• --dry-run: detect, classify, and report without editing files or running mutating commands.
• --only <id[,id...]>: limit work to named checks.
• --skip <id[,id...]>: omit named checks and record the omission in the report.

Reject unknown flags and combining --only with --skip.
