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).

+
+KARACHI: The counter-terrorism department on Wednesday claimed to have busted a gang involved in the recent cases of ‘short-term’ kidnapping for ransom in Karachi.
+
+CTD DSP Raja Umer Khattab said the gang used a Vigo, a four-wheel drive vehicle, and introduced themselves as “officials of law enforcement agencies” to their prey.
+
+The CTD received an intelligence report on April 22 that six to seven suspects were involved in the short-term kidnappings in the city, according to a CTD press release. They used a black Vigo double cabin and carried arms, walkie-talkies, handcuffs and hid their faces by using masks, the statement added.
+
+“The kidnappers took citizens to Steel Town by posing as officials of the Federal Investigation Agency, the CTD and intelligence agencies and used to release them after taking ransom.”
+
+Acting on a tip-off, a CTD team carried out an intelligence-based operation near Parking Plaza in Saddar and arrested four suspects — Imtiaz alias Salman, Ubaid Rehman alias Abi, Shahid alias Moosa and Saleem — and recovered snatched cell phones, three pistols, walkie-talkies, handcuffs and black colour Vigo with fake government number plate from their possession.
+
+During interrogation, the held suspects revealed that they kidnapped a citizen, Mohammed Ismail, in PIB Colony on April 13, and took him to a warehouse in Steel Town.
+
+They asked him about Bitcoin business and threatened him that he was involved in illegal work of Hundi/Hawala.
+
+Thereafter, they took his iPhone and asked him that they would contact him about money later on. They dropped him on Sharea Faisal near a stop.
