feat: sync JS client with C++ backend

Sync JS Client with C++ Backend

Summary

All 63 C++ API methods, 46 error codes, and 21 injected globals are now declared in the JS client. This PR ships 3 missing functions, 8 type/param fixes, 23 new error codes, and 6 missing Window globals — closing every gap identified in the C++->JS sync audit.

Fixes storage.setData null-crash bug where C++ throws on "data": null (now omits the field).

Changes

Missing Native Functions (3)

• app.getProcessId() — src/api/app.ts
• window.setBadge(count) — src/api/window.ts
• os.getLocale() — src/api/os.ts + LocaleInfo type (src/types/api/os.ts)

Parameter / Return Type Fixes (6)

File	Change
src/types/api/os.ts	ExecCommandOptions.envs, SpawnedProcessOptions.envs
src/types/api/os.ts	KnownPath — added 'desktop' | 'home'
src/types/enums.ts	LoggerType — added DEBUG
src/types/api/computer.ts	NetworkInterfaceInfo — values are NetworkInterfaceAddress[] (was singular)
src/types/api/clipboard.ts	ClipboardImage — added alphaShift, alphaMask

Bug Fix

• src/api/storage.ts — setData no longer sends data: null when value is null/undefined, avoiding C++ nlohmann crash. Uses conditional payload.

Error Codes — 23 new, 46 total (src/types/api/protocol.ts)

Added all codes from C++ errors.h:

• Filesystem (10 new): NE_FS_REMVERR, NE_FS_NOTADIR, NE_FS_COPYERR, NE_FS_MOVEERR, NE_FS_FILOPER, NE_FS_UNLTOUP, NE_FS_UNLTFOP, NE_FS_UNLCWAT, NE_FS_NOWATID, NE_FS_UNLSTPR, NE_FS_ACSFAIL, NE_FS_CHMDERR, NE_FS_CHWNERR
• OS (4 new): NE_OS_UNLTOUP, NE_OS_INVNOTA, NE_OS_TRAYIER, NE_OS_UNLTRAS
• Storage (3 new): NE_ST_NOSTKEX, NE_ST_STKEYRE, NE_ST_NOSTDIR
• Computer (4 new): NE_CO_UNLTOSC, NE_CO_UNLTOMG, NE_CO_UNLTONI, NE_CO_UNLTOSK
• Window (1 new): NE_WI_UNBSWSR
• Resources (5 new): NE_RS_TREEGER, NE_RS_UNBLDRE, NE_RS_NOPATHE, NE_RS_FILEXTF, NE_RS_DIREXTF
• Server (4 new): NE_SR_UNBSEND, NE_SR_UNBPARS, NE_SR_MPINUSE, NE_SR_NOMTPTH
• Config (4 new): NE_CF_UNBLDCF, NE_CF_UNBPRCF, NE_CF_UNSUPMD, NE_CF_UNBLWCF

Also organized all codes under named section comments and removed a duplicate NE_ST_STKEYWE.

Missing Window Globals (6)

Added to declare global { interface Window { ... } } in src/index.ts:

• NL_COMMIT — server commit hash
• NL_CONFIGFILE — config file path
• NL_COMPDATA — compilation data
• NL_LOCALE — system locale
• NL_SINJECTED — server-side injection flag
• NL_WSAVSTLOADED — window saved-state loaded flag
