release: cut V0.5-9 — UX-fidelity de-fabs + DLM H5 + TCP/IP config plane + GCC rungs

[baron-3dl]

Version bump V0.5-8 → V0.5-9 (OVMX_PRODUCT_VERSION identity SSOT INV-1 + os-release VERSION/VERSION_ID, vms-8328 gate). 28 commits since V0.5-8.

Highlights

UX-fidelity (vms-050 oracle-driven program):

• vms-050: oracle-faithful SHOW VERSION/VERIFY IVKEYW (no fabricated command); clock is demo-snapshot artifact #882 oracle-faithful SHOW VERSION/VERIFY — removed the fabricated SHOW VERIFY command, IVKEYW -E-→-W-; first oracle-golden gate
• vms-050: de-fab SHOW PROCESS/QUOTAS + SHOW QUOTA — real SYSUAF/JIB quotas / honest NODISKQUOTA (no fabricated constants) #884 SHOW PROCESS/QUOTAS de-fab — excised the hardcoded quota block, honest omission + wired read path (INV-6)
• vms-d4ef: interactive login is a distinct executive process (fresh pid + establish_system), not a JOB_CONTROL continuation #883 interactive login is a distinct executive process (fresh pid + establish_system) — SHOW SYSTEM stops aliasing the login onto JOB_CONTROL's pid
• vms-28a: F$GETSYI("VERSION") returns the real VMS fixed 8-char space-padded field #866/vms-76c3: wire F$GETSYI("ARCH_NAME") in the DCL lexical + running per-arch battery coverage #868 F$GETSYI VERSION/ARCH_NAME real fields; SHOW-fidelity cut 1: SHOW CPU column-0 layout + /BRIEF /FULL summary line #861 SHOW CPU layout; vms-6a6: wire device-table + terminal ioctls into the VAX executive → green the VAX acceptance gate #863 VAX SHOW USERS classification

Cluster 0.6: #875 DLM rung H5 two-node SCS wire; #873 DLM rung-3 cross-node contention (block-then-grant + BLKAST + $DEQ)
Networking: #878 TCP/IP Services config/management plane (the VMS-way IP config)
Toolchain: #869/#870/#871 GCC CRTL/RMS/FP joint-e2e rungs (real zlib links zero-deferred)
Alpha: #867 boot regression fix (per-arch O_* ABI); #879 TCG-tolerant syssvc deadlines
Runtime: #881 ACP backing-device cache (PRODUCT INSTALL persist)
