Add first-class conflict resolution support to jj.nvim.
- add `jj.cmd.resolve` to run `jj resolve` in a floating terminal or via an
external tool
- add `:J resolve` with support for `-r/--revision`, `--tool`,
`--external/--ext`, and positional filesets
- integrate resolve into the log buffer with the `gr` mapping and optional
`resolve_strategies` picker
- add `utils.is_change_conflicted()` and avoid opening resolve when the
selected revision has no conflicts
- document resolve usage, config, and keymaps in the README
- add tests for resolve arg parsing and conflict detection helpers
Use raw command output for jj file reads, add encoding-aware decode/encode
handling, preserve buffer encoding settings across revision buffers, and add
tests for BOMs, endianness, and roundtrip behavior.
Convert blocking jj commands to async using vim.fn.jobstart() to prevent UI
freezing during fetch, push, rebase, squash, and other heavy operations.
Changes:
- Implement execute_command_async() in runner with proper error handling
- Captures stdout from job and passes to success callback
- Supports stdin input for commands that require it
- Includes silent flag to suppress error notifications
- Replicates sync version's error handling behavior
- Convert blocking operations to async:
- handle_log_fetch, handle_log_push_all, handle_log_new
- handle_log_edit, handle_log_abandon, handle_log_describe
- describe.execute_describe, all init.lua commands
- Add push/fetch as public commands with CLI support:
- M.fetch() - fetch from remote
- M.push(opts) - push all changes or specific bookmark
- CLI: :J push, :J push <bookmark>, :J fetch
- Implement handle_log_push_bookmark() for revision under cursor:
- Retrieves and strips modified bookmark indicator (*)
- Pushes specific bookmark to remote
- Keybind: Shift+p in log buffer
- Update README with new keybinds:
- a: abandon revision under cursor
- f: fetch from remote
- p: push all changes
- Shift+p: push revision's bookmark
- Add Lua API docs for push command options
