* test(3255): add red/green tests for --json-errors structured error mode
Ten tests covering the --json-errors mode contract:
- Unknown command → sdk_unknown_command
- Dotted unknown command → sdk_unknown_command
- Missing --pick value → usage
- Config key not found → config_key_not_found
- Unknown subcommand → sdk_unknown_command
- GSD_JSON_ERRORS=1 env var activation
- Successful command unaffected
- Stable error shape ({ok, reason, message})
- Single error line per invocation
- Unknown flag → usage
All assertions use JSON.parse on stderr captures, never .includes() on
text (#2974 / CONTRIBUTING.md "Prohibited: Raw Text Matching" rule).

* feat(3255): add typed ERROR_REASON codes and GSD_JSON_ERRORS env var support
- Destructure ERROR_REASON from core in gsd-tools.cjs
- Add GSD_JSON_ERRORS=1 env var as alternative to --json-errors CLI flag
- Pass ERROR_REASON.SDK_UNKNOWN_COMMAND to unknown top-level command default path
- Pass ERROR_REASON.SDK_UNKNOWN_COMMAND to unknown intel subcommand path
- Pass ERROR_REASON.USAGE to --pick missing value error path
- Pass ERROR_REASON.USAGE to --version flag rejection path
All ten tests in feat-3255-json-errors-mode.test.cjs pass.

* fix(gsd-tools): document --json-errors in usage/help text (#3255)
Add [--json-errors] to the TOP_LEVEL_USAGE synopsis line and introduce a
"Global flags:" section describing all four global flags (--raw, --pick,
--cwd, --ws) plus --json-errors with its GSD_JSON_ERRORS=1 env-var
alternative, so operators can discover the flag via `gsd-tools --help`.

* chore: drop redundant CHANGELOG.md edit (use .changeset/ fragment per CONTRIBUTING.md)
