dsh-ledger-wealth: DSH Local Ledger and Wealth Holdings Plugin

ainachoneko's DSH plugin, dsh-ledger-wealth, consolidates daily bookkeeping and wealth holdings into a single session, while maintaining ledger and wealth data in separate tables and reports without merging. It supports receipt OCR, database persistence upon confirmation, running balance, a six-level fallback chain for fund returns, and monthly double-festival reports; data is stored in `~/.dsh/ledger-wealth/ledger.sqlite`. Installation is done via `node scripts/install-into-dsh.mjs`, allowing time zones, scheduled tasks, fund interfaces, and OCR to be overridden in the profile. Local-first and released under MIT 1.0.0, it is suitable for DSH users who require an auditable personal finance workflow.
