Add commit description parsing to git backends#46
Merged
Conversation
Commit messages consist of a subject (first line) and an optional body (everything after the first blank line). Previously only the subject was captured. This change stores the body in a dedicated `description` column so it is available alongside the subject for downstream use. Changes: - Add `Description` field to the `Commit` struct - Native git parser: extend format string with `%b%nGITANALYTICS_ENDMETA` and collect body lines until the end marker - Go-git parser: split `c.Message` on `\n\n` to separate subject from body - Schema: add `description TEXT NOT NULL DEFAULT ''` to commits table DDL - Store Init(): run `ALTER TABLE commits ADD COLUMN description ...` to migrate existing databases (no-op if the column already exists) - InsertCommits(): include description in the INSERT statement - Tests: add `initTestRepoWithDesc` helper and description assertion tests for both the native and go-git implementations https://claude.ai/code/session_01HJ7FLDkYneKyCiTtGHoRQ8

Summary
This PR adds support for parsing and storing commit message descriptions (body text) in addition to subject lines across both git backends (go-git and native git). The description is now extracted, stored in the database, and available for analysis.
