feat(sources): fetch linked URLs for the 252 spreadsheet-only cases

Until now only cases 357+ (plus a few older ones) had their linked URLs
fetched; the other 252 dossiers held just the text pasted into the
spreadsheet, often only the lede. This pass fetches every linked URL for
those cases so the full text is on file before link rot takes it.

- stage_all.py: new --include-sheet-cases flag that lifts the skip on
  cases holding spreadsheet articles. Resumable as before.
- staging/: raw extracts and index.json for the 252 cases.
- sourced-articles.json, case-files-manifest.json: 188 new UNTRIMMED
  blocks. 179 cases gained at least one fetched article; 73 got none
  (49 BLOCKED, 18 THIN, 9 DEAD, 4 video/social, 3 ERROR).
- sources/*.txt: rebuilt with build_cases.py --all. Sheet pastes are
  kept; fetched blocks sit beside them under the NOT YET TRIMMED banner.
  Files previously committed with CRLF are now LF.
- wayback-availability.json: Wayback snapshots exist for 73 of the 98
  failed URL slots; input for an archive-fetch pass.
- README-START-HERE.md: progress note and next step.

verify_all.py PASSES (1836 checks).

+
+Three Emirati men were charged at the Dubai Court of First Instance on Monday for allegedly posing as cops and kidnapping three Indian traders to a desert location to rob 25 bitcoins from them.
+
+According to public prosecution records, the trio, aged 19, 27 and 20 (student), conned the victims into riding in their car after falsely claiming that they were being wanted by authorities for dealing in the virtual currency.

+
+They then drove to a remote desert location off Al Barsha where they used the victims' laptop to transfer 25 bitcoins from their account into the account of one of them in Japan. The trio was charged with kidnap, impersonation and online misappropriation of the virtual currency.
+
+They had four Indian accomplices, aged between 21 and 47. Those are accused of possessing Dh250,000, under circumstances suggesting that the money was ill-gotten.
+
+The incident took place on March 14, 2017, and a case was registered at Al Barsha police station.
+
+A Yemeni woman, who works as a driver for one of the traders, recounted during the prosecution investigation, how she met the first Emirati defendant. "I worked with my sister for the traders. Many people of different nationalities would come to their villa to buy bitcoins. The 19-year-old accused contacted me and then met me and my sister at a restaurant."
+
+However, in the meeting, the accused told the sisters he is a security official and that the trader is being wanted in India in connection with forgery and fraud crimes. "He asked for our help, claiming we would get Dh500,000 as a reward for our cooperation. He also claimed we would land lucrative jobs for our help."
+
+She stayed in contact with that defendant for some time to keep him posted about the trader's movements until the incident day.
+
+One of the victims, a 35-year-old Indian investor, told the prosecutor that he was with the other two traders when a car intercepted them after 10pm. "The suspects pulled us out of the car and took our money and mobile phones."
+
+The complainants were then taken to a remote spot where the suspects yelled at them that they were fraudsters and would be deported. One of their laptops was then used to transfer bitcoins to an account belonging to the 27-year-old defendant.
+
+The trial continues on December 13.
