v1.58.7

[1.58.7] — 2026-05-20

fix(security): NEW-2 — isValidJobUrl now rejects paired template-placeholder syntaxes (${…}, {{…}}) to match the error message. The route-level 400 returned by POST /api/pipeline advertises "contain no script or template characters", but the v1.58.3 MASTER regression confirmed only ASP/EJS-style <%…%> was actually blocked (free side effect of the [<>"'\\s] bracket-char gate). JS template literals (${TEST}) and Mustache/Handlebars ({{TEST}}) both passed validation — a regex↔message semantic gap. Option A from the fix-prompt (tighten regex to match message; slight hardening against URL-templating injection): a new TEMPLATE_PATTERNS array in [server/lib/security.mjs](server/lib/security.mjs) (/${[^}]}/, /{{[^}]}}/) is consulted via hasTemplatePlaceholder(url)beforenew URL(…). Only **paired** placeholders are rejected — a bare {normal} ATS-style path token survives (https://boards.greenhouse.io/anthropic/jobs/4567` and https://example.com/job/{normal} both still accepted). 901 → 903 unit (tests/url-validation.test.mjs extended with 2 NEW-2 tests covering both rejected forms and the no-false-positive ATS case). The <%…%> regression-lock is also explicit now. (NEW-2)
