release: prepare v0.1.1248 RC for staging verification

[kwakayama]

Purpose

Set the next patch line to 0.1.1248-rc so CI can publish a numbered RC and deploy the current framework to staging consumers.

Changes

• Set deno.json to 0.1.1248-rc.
• Keep the runtime version constant synchronized.
• Regenerate the version-bearing hydration runtime with Deno 2.7.7.

Verification

• 23 focused release, RC preparation, generated-artifact, and binary tests passed
• formatting, lint, and typecheck passed in the pre-push gate
• full unit gate completed 30,505 steps: 3,961 tests passed; four unrelated timing/race assertions failed under parallel load
• the failed deadline-race assertion also fails unchanged on clean origin/main
• hydration runtime generated-artifact freshness check passed
• git diff --check passed

Gate

Do not merge until the required pre-release E2E deployment checks are green.

Merging publishes 0.1.1248-rc.<run_number> and dispatches staging builds to downstream services.

Summary by CodeRabbit

• Chores
  • Updated the application version to 0.1.1248-rc.
