refactor: replace TODO comments with clear decisions and context

Replace vague TODO comments with actionable decisions, design notes, and
clear rationale for current implementations across socket-cli codebase.

**Decision Updates:**
- json.mts: Clarify validation unnecessary for optional SocketJson properties
- arborist-helpers.mts: Document URL.parse compatibility approach for Node 18+
- handle-patch-status.mts: Explain root-level node_modules scanning limitation
- init.gradle: Clarify Gradle repository and configuration choices

**Feature Requests:**
- cmd-manifest-cdxgen.mts: Document yargs→meow conversion complexity with
  Socket CLI's custom meow implementation

**Design Notes:**
- with-subcommands.mts: Document spinner circular dependency and refactoring
  opportunity (2 locations)
- cmd-scan-create.mts: Note projectIgnorePaths documentation opportunity

**Known Issues:**
- cmd-pnpm.test.mts: Document test failures needing investigation
- bootstrap-stub.md: Change signature verification to future enhancement

All changes maintain existing functionality while providing clearer context
for future development. No behavioral changes.
