rustledger-completion

Editor-agnostic completion logic for Beancount sources.

This crate is the single source of truth for the completion logic shared between the rustledger LSP server (rustledger-lsp) and the WASM editor (rustledger-wasm). It is deliberately pure: no clock access, no lsp-types, no wasm-bindgen. Callers supply the live data (account / currency / payee / tag / link string lists and "today's" date) and map the neutral CompletionCandidate results into their own editor-specific item types.

It provides:

• offset_to_byte — map a position (UTF-8, UTF-16, or character offset) to a char-boundary-safe byte offset.
• classify_context — classify the text before the cursor into a CompletionContext.
• *_candidates functions — produce neutral CompletionCandidate lists for each context.
