v0.4.0

Added

• Added a spending-over-time chart in the Dioxus UI.
• Added manual value assets so non-priced holdings can be included in portfolio valuation.
• Added stacked net worth charts and tooltips for drilling into portfolio composition.
• Added a recurring transaction review UI backed by persisted recurring review state.
• Added recursive tag hierarchy configuration for aliases, parent tags, and rollups.

Changed

• Replaced legacy transaction categories with tag and subtag based classification.
• Updated spending, transaction rule, batch tagging, TUI, and AI rule flows to use the tag model consistently.
• Improved portfolio, spending, and balance outputs so tag hierarchy and manual value assets are reflected in derived reports.

Fixed

• Kept host-local Git SSH key paths out of shared keepbook.toml.
• Prevented automated data commits from staging keepbook.toml, so local machine settings are not pushed with portfolio or sync snapshots.
