feat(job-scraper): per-portal enabled toggle honored by /scrape (#160)

Implements the mechanism approved in discussion #93: enabled: true|false frontmatter on portal skills (missing key = enabled), honored during /scrape portal discovery, with skipped portals reported visibly in the run summary.

 Discover all installed portal CLI skills by reading every `SKILL.md` found under `.agents/skills/*/SKILL.md`.

-For each installed portal skill:
+**Honor the `enabled` toggle.** A portal is enabled unless its `SKILL.md` frontmatter sets `enabled: false` (a missing key means enabled — the default). Skip each disabled portal and record it for the Step 5 summary. A fork can thus keep a portal installed but sit out a run without deleting its directory.
+
+For each **enabled** portal skill:
 
 1. Read its `SKILL.md` to find the correct `bun run …` invocation and supported flags.
 2. Translate the query terms from `search-queries.md` into that portal's flag format (e.g. `--key`, `--search-string`, `--query`, filter codes — whatever the portal's SKILL.md specifies).
