refactor: remove User Stories 4 and 5 from specification

Removed User Stories 4 (Vault Navigation) and 5 (Advanced Features)
from the project scope to focus on core functionality:

Scope Changes:
- spec.md: Removed US4 and US5 user stories and acceptance scenarios
- spec.md: Removed FR-008 through FR-015 (daily notes, templates,
  bookmarks, plugins, themes, file/folder listing)
- spec.md: Renumbered remaining FRs sequentially (FR-009 through FR-019)
- spec.md: Updated success criteria SC-006 to reflect targeted scope
- tasks.md: Removed Phase 6 (US4, 18 tasks) and Phase 7 (US5, 67 tasks)
- tasks.md: Renamed Phase 8 to Phase 6 (Polish)
- tasks.md: Updated tool counts from 95 to 20 tools
- tasks.md: Updated total tasks from 165 to 98 tasks

Remaining Scope (3 User Stories):
- US1 (P1): File Operations - 9 tools ✅ Complete
- US2 (P2): Search & Discovery - 11 tools ✅ Complete
- US3 (P3): Task & Property Management - 18 tasks pending

Rationale:
- Focus on foundational workflows (file operations, search, tasks)
- Reduce complexity and maintenance surface area
- Ship a solid core feature set rather than comprehensive coverage
- US4/US5 can be added later if needed

Impact:
- Reduced task count by 67 tasks (40% reduction)
- Simplified dependency tree (3 user stories vs 5)
- Faster path to production-ready bundle
- Clearer MVP definition

Files changed:
- specs/001-obsidian-mcp-bundle/spec.md
- specs/001-obsidian-mcp-bundle/tasks.md

Build: ✅ (no code changes, spec only)
