feat(sources): Wayback pass, automatic trimming, detention rule, ten cases re-sourced

Second and third rounds on the dossier pipeline, reviewed locally before commit.

Retrieval
- wayback_pass.py: retries every BLOCKED/DEAD/THIN/ERROR linked source through
  the Wayback Machine; blocks carry the snapshot date, archive URL and the live
  verdict. 143 slots retried: 93 fetched, 37 no snapshot, 12 script shells, 1 PDF.
- fetch_sources.py: fetch_wayback() helper.
- add_extra_sources.py: files staged extra_* finds (web search, not on the DB
  record) into the store with a provenance note.
- Cases re-sourced by web search: 248 (Oslo: Document.no, Avisa Oslo, NRK; the
  linked Le Parisien piece is case 242 and is marked OFF-CASE), 258 Kharkiv,
  260 Singapore, 358 Bangkok, 365 Las Vegas, 388 Verneuil-sur-Seine, 390 Zoersel,
  430 Homestead. 341 of 364 cases now hold a fetched article; 11, 66 and 399
  have no public text source (podcast, police video, direct victim report).

Trimming
- auto_trim.py: case-anchored furniture cut for UNTRIMMED blocks. Finds the body
  run that mentions the case, merges across subheadings and short furniture
  gaps, drops teasers, share bars, date/URL/caption lines and subscription
  pitches; refuses pages with no record term or almost no body. 302 blocks
  trimmed; 16 left on auto-trim-review.md (7 OFF-CASE suspects). Every cut is
  labelled AUTO-TRIMMED, UNREVIEWED in the dossier; the full extract stays in
  staging/. Decisions with anchors in trim-decisions-auto.json.
- build_cases.py / verify_all.py: banners for auto-trimmed and archived blocks,
  staged-file check extended to Wayback blocks, flag legend under the record.

Detention rule
- README "Definitions": the DB field `kidnappings` is the DETENTION violence
  type (victim, guard, staff or relative held to force submission or execute
  the theft), distinct from the Kidnapping scenario (taken away and held).
- detention-flag-review.md / detention-flag-corrections.json: 40 records
  reviewed with evidence; 30 set-to-1 proposals accepted by the owner on
  2026-09-06 (listed in corrections-approved.md), 10 still open.
- apply_detention_wording.py: "Violence Used" in the 70 reviewed summaries now
  names detention explicitly (62 of 70 labelled), supported by the summary's
  own text; idempotent; supersedes the batch scripts' wording.

Worklist and docs
- sofia-worklist.md: 248 decisions, detention rule item replacing the old
  "no abduction" item, fresh-search section for the textless cases.
- README-START-HERE.md: progress notes, run commands, next steps.
- Bug fixed in passing: Wayback blocks stored in-memory text with carriage
  returns; now stored as read back from disk.

verify_all.py PASSES (2321 checks).

+Man in S'pore for crypto Token2049 event says he was 'jumped', but those sceptical say country 'safe'
+
+A man claimed that he was robbed while he was walking home after a cryptocurrency event held in Singapore.
+
+Nate Geier, a co-founder of a software development company, was in town for Token2049. The annual event is dubbed the "largest crypto event" and is held from Sep. 29 Oct. 8 at Marina Bay Sands Convention Centre.
+
+Taking to X on Oct. 3, Geier posted a picture of himself with facial injuries and said that he "must have gotten jumped walking home" after Token2049.
+
+In the post, he wrote that he considered himself "a seasoned traveller", but only remembers "waking up in a hospital".
+
+"Passport and ring gone. Be careful out there at Token2049," he added.
+
+In the photo he posted, the right side of Geier's face was severely bruised, and he had a cut along his nose.
+
+Consider myself a seasoned travler. Just remember waking up in a hospital, very scary.

+
+When a user asked what had happened, Geier said that it occurred at 11pm and that he "never lost memory like this".
+
+Geier shared that he had filed a police report on Oct. 3 and will visit the police headquarters on Oct. 6 for further updates.
+
+While numerous users wished Geier a speedy recovery and hoped the culprit would be caught, others expressed their doubt that Geier had actually been robbed.
+
+Commenters stated that Singapore is a "very, very safe" country, with closed-circuit television cameras located, and asked Geier for proof of the incident.
+
+Some also speculated that Geier could have been "inebriated".
+
+Mothership has reached out to Geier for more information.
