agents-init currently swallows a failed rebase and then stages and commits
whatever is in the tree, which records conflict markers under a routine
message. No AGENTS repo has a remote today so the pull never runs, but the
vault gives these repos remotes and arms it.
The shared helper aborts the rebase, commits nothing, and returns 2. It
also redirects git's own stdout during the pull/abort: git prints
"CONFLICT (content): ..." to stdout, not stderr, so without this the
message would leak into the helper's own stdout instead of staying
diagnostic-only.
The conflict fixture commits "ours" locally before diverging, since an
uncommitted worktree change has nothing for --autostash's rebase step to
replay -- it fast-forwards cleanly and only the stash pop would conflict.
Enforces the rails the vault depends on: only directories are linked
(agent editing tools refuse to write through a symlinked file), a missing
target is refused rather than turned into a dangling link, and adopting a
populated live directory copies without clobbering.
Also fixes slug sanitization in _agents_repo_slug to apply the same
[^a-z0-9._-] → - mapping to the fallback (no-remote) branch, ensuring
local project slugs are filesystem-safe and won't leak special chars like
spaces or exclamation marks.
Keys a project by its remote rather than its path so the key survives a
machine change or a directory rename. Falls back to a path-derived
local-* key when no remote exists.
Adds a hermetic test harness that builds throwaway repos under mktemp.
Adds tests/run-tests.fish (syntax lint over every .fish file, plus a
sandboxed interactive load) and tests/functional.fish (10 checks
covering XDG/PATH/CDPATH setup, key bindings, abbreviations, core
functions, exit rewiring, and the opinionated-component registry).
The sandbox copies config-relevant files into a scratch HOME/XDG tree
rather than symlinking the checkout, since this repo also serves as a
live ~/.config/fish and a symlink would let universal-variable writes
leak into the real fish_variables file.
Wires the suite into build-docs.yml as a `test` job that `build-docs`
now depends on, so a broken config can no longer get published to the
docs site. Documents the workflow in the README's new Testing section.
