`FirstRunDetector.detectExistingProjects()` walks ancestor directories
looking for `.fusion/` projects, stopping only at `homedir()` and the
filesystem root. On systems where a prior Fusion session has left a
`/tmp/.fusion/fusion.db` (e.g. running tests, ephemeral dashboards,
crashed processes), the walk crosses into `/tmp` and incorrectly
"discovers" that stale state as a project.
This was caught by tests in packages/core/src/__tests__/store.test.ts
that intermittently failed when a real Fusion session had been run
on the same box. The walk would find the test's tmp dir AND the host's
real `/tmp/.fusion/fusion.db`, polluting the project-detection invariants.
Fix: import `tmpdir` from `node:os` and add it as a third walk-stop
boundary alongside `homedir()` and `/`. The OS temp directory is a
shared system surface and should never itself host a project.
The bug affected any user with a stale `/tmp/.fusion/` from a previous
session — invisible most of the time, but caused FirstRunDetector to
misclassify project state.
Tested: 4 previously-flaky tests in packages/core now pass deterministically.
Drops the .kb/kb.db migration path, legacy backup filename handling, and
backward-compat test suites. Renames internal kbDir identifiers to
fusionDir and hasKbProject/isValidKbProject to their fusion equivalents.
- Remove needsCentralMigration, autoMigrateToCentral, and the
"needs-migration" FirstRunState; checkAndMigrate and KB_SKIP_MIGRATION
env var are gone
- Remove LEGACY_BACKUP_DIR and canonicalizeBackupDir; listBackups no
longer matches kb-* filenames
- Delete backward-compat.test.ts and store-backward-compat.test.ts;
update remaining tests to new 3-state first-run model

- Reorder dashboard TUI sections so System is tab [1] and the initial active view
- Update header rendering across wide, medium, and narrow terminal layouts to reflect the new tab order
- Expand dashboard TUI tests to assert system-first labels and default active section behavior
- Document system-first startup behavior in CLI reference and add a patch changeset for @runfusion/fusion
- Fix TaskStore regressions from multi-project and mission integration
- Sync fresh schema with task persistence (missionId, baseCommitSha columns)
- Align backward compatibility with .fusion projects (kb.db naming)
- Add project overview and selector styles for dashboard
- Cover exact-name project resolution in tests
- Use Nerd Font for terminal integration
- Restore SetupWizardModal from main branch
- fix TaskStore.getOrCreateForProject to resolve projects through BackwardCompat and support legacy .fusion/.kb detection
- add regression tests for exact-name project lookup, legacy cwd fallback, and fresh-schema task create/update persistence
- sync the tasks schema definition with missionId support so fresh databases match runtime migrations
