fix: surface store sync failures + add secrets sync (EGB-1230, EGB-1231)

EGB-1230: `cmd_pull` synced the store with `git pull >/dev/null 2>&1` under
`set -euo pipefail`. A store that couldn't fast-forward killed the script at
that line with git's exit 128 and nothing on stdout or stderr — a banner, no
restored files, no reason, and invisible in a pipeline. The sync now routes
through `_store_sync_pull`, which guards the pull, captures git's output as
the diagnosis, and dies naming the store path and `secrets sync`. It is now
`--ff-only` to match the push path, so a plain pull can no longer manufacture
a merge commit in the store.

EGB-1231: once a store diverged there was no way out — push demanded a
fast-forward and pointed at pull, which couldn't fast-forward either, so the
advice looped and recovery meant hand-running git next to encrypted blobs.
Adds `secrets sync`: fetch, stash, rebase onto the remote, restore the stash,
then a confirmation-gated push of local commits (`--yes` to skip the prompt,
`--dry-run` to report only). Non-destructive by construction — no merge, no
force-push, no `reset --hard`, no `stash drop`; a rebase conflict names the
conflicting files and leaves the store exactly as found. `secrets which` gains
a `remote:` line reporting ahead/behind/dirty, and push's dead-end message now
points at `sync`.

test/sync.bats: 25 new tests. Full suite 353/353 green.

And you'll be told when you're behind: if a store was last written by a newer `secrets` than the one you're running, any command prints a one-line nudge to stderr (non-fatal) — and `secrets which` shows the store's `written-by:` version. Stores written by older builds (no version stamp) stay silent.
### When the store diverges
The store is a git repo, so two machines pushing at once can leave your clone
both ahead and behind its remote. `secrets push` needs a fast-forward and
`secrets pull` won't silently merge, so both stop and tell you to run:
```bash
secrets sync
```
`sync` fetches, stashes any uncommitted blob edits, rebases your local commits
onto the remote, restores the stash, and then *asks* before publishing your
commits to the shared store (`--yes` skips the prompt; `--dry-run` just
reports). If the rebase conflicts, it aborts, restores your stash, names the
conflicting files, and leaves the store exactly as it found it — nothing in
the path force-pushes, hard-resets, or drops a stash.
`secrets which` now reports the same state up front, so you can see it coming:
```
store: /Users/you/.secrets
source: default
format: v2
remote: ahead 1, behind 11, 3 modified (run: secrets sync)
```
### Automatic project detection
When you run `secrets push` or `secrets pull` without specifying a project name, the tool figures out which project you're in by:
