test(e2e): verify M5 success criteria — ACMS and large-project context

Robot Framework E2E test suite exercising the complete M5 success
criteria verification sequence:

- Large project creation with 10,000+ simulated files
- Resource registration and linking to a project
- Indexing verification (resource linked, project shows correctly)
- Context tier management (hot/warm/cold) via ContextConfig
- ACMS v1 context policy set/show with persistence round-trip
- Phase view inheritance (default → strategize → execute → apply)
- Scoped context output per ACMS phase with narrowing size limits
- Policy clear and inheritance fallback
- ContextView validation rules (size limits, VALID_PHASES)

Nine subcommands in the Python helper, each printing a sentinel
string on success. All subcommands verified passing locally.

Closes #406

+"""Robot Framework helper for M5 E2E verification tests.
+
+Exercises the complete M5 success criteria sequence:
+  1. Large project creation with 10,000+ simulated files
+  2. Resource registration and linking to a project
+  3. Indexing verification (resource linked, project shows correctly)
+  4. Context tier management (hot/warm/cold) via ContextConfig
+  5. ACMS v1 context policy set/show with persistence round-trip
+  6. Phase view inheritance (default → strategize → execute → apply)
+  7. Scoped context output per ACMS phase
+  8. Policy clear and inheritance fallback
+
+Each subcommand prints a sentinel string on success and exits 0.
+On failure it prints a diagnostic to stderr and exits 1.
