B:BD[2.7835] → [2.7835:7914]

Added `requireFlags()` and `requireNonZeroFlags()` helpers in `cmd/common.go`.

[2.7835]

[2.7914]

Added `checkFlags()`, `checkNonZeroFlags()`, and `requireFlags()` helpers in `cmd/common.go`.

Insertion in CHANGELOG.md at line 57 [3.1197933]

[2.8099]

Converted core Run* functions to return `error` instead of calling `os.Exit`:
- All CRUD commands (create/update dataset/location/cluster/pattern)
- sql, export, replay, xxhash, metadata, isnight, prepend, time
- Top-level dispatchers: RunImport, RunCalls, RunCreate, RunUpdate, RunExport, RunReplay
main.go now uses a `commandDispatch` map and has a single error-handling
exit point. Reduced main() complexity from 15 to ~4.
Calls_* subcommand functions and import.go internal functions still use
os.Exit internally — to be converted in a follow-up pass.
