fix(core): make follow-up execution aware of the saved plan file

[shssoichiro]

Context

Users launching a follow-up implementation session now get an explicit plan-file path and instruction to read it first, so execution stays aligned with the canonical plan even when copied plan text drifts.

Fixes #8478

How to Test

• Make a plan in Plan mode
• Implement via "Start new session" prompt
• Verify the implementation session receives an instruction to load the plan file, and loads it

File	Line	Issue
packages/opencode/src/kilocode/plan-followup.ts	184	resolvePlan() still reads Session.plan(session) under the caller's instance, so if the saved plan has to be reloaded from disk after switching worktrees it can open the wrong file or return an empty plan.
