fix(scrape): use the full job_scraper/seen_jobs.json path in every step of the spec (#608)

* fix(scrape): use the full job_scraper/seen_jobs.json path in every step of the spec

Step 0 reads job_scraper/seen_jobs.json but Steps 1-4 and the rules used the bare
filename. Step 4 is where the file is written, so an agent following it literally
can create seen_jobs.json in the repo root, outside the **/job_scraper/seen_jobs.json
ignore rule, where it gets committed with the user's scrape history.

Adds a spec test that rejects bare references; relaxes the existing dedup-continuity
regex to accept the qualified path.

* docs(changelog): entry for #608

+"""Every seen_jobs.json reference in /scrape's spec names the full path.
+
+Step 0 reads `job_scraper/seen_jobs.json`, but later steps (notably Step 4,
+where the file is written) used the bare filename. An agent following Step 4
+literally can create `seen_jobs.json` in the repo root. The ignore rules only
+cover `**/job_scraper/seen_jobs.json`, so a root-level copy is untracked-by-rule
+only by accident: it shows up in `git status`, gets swept into a commit, and
+publishes the user's scrape history. Pinning the full path in the spec keeps
+the read path, the write path and the ignore rule pointing at the same file.
