synth v0.72.0

What's Changed

• plan(v0.72): 8 artifacts ranked by who is blocked — two of them exist because the v0.71 tag REFUSED to close their issues — and MOVE THE ANCHOR to v0.71.0 by @avrabe in #1361
• RQ-72-STACKDOC (#1341 item 3): the stack number exists and the page an embedder reads never named it — including what synth cannot see by @avrabe in #1362
• RQ-72-ISLANDS (#345): place the literal pool where the load can reach it — the pool that existed and could not be reached by @avrabe in #1363
• RQ-72-CIPOOL (#1062 increment 3): pin the ubuntu-latest share structurally — and earn 55 -> 52 in the same PR by @avrabe in #1364
• RQ-72-ISSUEGATE (#1250): the closure gate now gets asked, tells the truth, and R12 has teeth by @avrabe in #1365
• RQ-72-RITUAL (#1269): commit the merge and tag rituals, with both named defects fixed and a self-test CI runs by @avrabe in #1366
• RQ-72-ARCHMODEL (#1136): the seventh consecutive N/A, with the tags proven load-bearing by @avrabe in #1367
• cold review v0.72: a shipped silent miscompile in RQ-72-ISLANDS, plus seven gate-potency corrections by @avrabe in #1370
• RQ-72-ARM64MUSL (#1349): the second triple ships, and the execution red was not the defect its label named by @avrabe in #1368
• RQ-72-VEX (#1359): publish a CycloneDX VEX — and make every not_affected human-asserted by construction by @avrabe in #1369
• cold review round 2: the island fix had its own blind spot, plus the prose-truth findings by @avrabe in #1371
• release(v0.72.0): "Built, and out of reach" — 8 artifacts, two rounds of cold review by @avrabe in #1372
