[Bug]: spec.implement cannot locate tasks.md (file is at specs/master/tasks.md)

[kfinkels]

Bug Description

spec.implement is looking for tasks.md in the wrong path, likely the project root or current working directory.

Steps to Reproduce

1. Run the full spec flow: /spec.specify → /spec.clarify → /spec.plan → /spec.tasks
2. Verify tasks.md exists at specs/master/tasks.md
3. Run /spec.implement
4. Command fails to find tasks.md

Expected Behavior

/spec.implement should resolve tasks.md from specs/master/tasks.md and proceed normally.

Actual Behavior

/spec.implement fails to find tasks.md even though the file exists at specs/master/tasks.md. The command falls back to plan.md instead of reading the correct file.
