JinjingandOrca 4908a03671 fix: dedupe fork-copied usage history across Claude, Codex, and OpenCode scanners (#8023)
* fix: dedupe fork-copied usage history across Claude, Codex, and OpenCode scanners

Coding-agent CLIs copy transcript/rollout history into new files on
resume/fork, and the usage scanners deduped per-file only (or not at
all), so copied history was re-counted once per descendant file
(issue #8006: 38.6B tokens / $72,981 reported vs ~2.3B real).

- claude-usage: cross-file turn ownership keyed on message.id:requestId;
  per-file ownedDedupeKeys persisted; deterministic sorted-path claim
  order; schema v3 -> v4 so inflated caches rebuild.
- codex-usage: cross-file token_count event ownership keyed on the raw
  record identity (sessionId + timestamp + token tuples); fixes both the
  copied-prefix re-count and the total-only branch that re-counted the
  entire cumulative session per descendant rollout; legacy
  .orca-session-copies skip-bytes bridge unchanged; schema v3 -> v4.
- opencode-usage: each sessionId is counted from exactly one database;
  the canonical opencode.db claims ahead of stale sibling copies
  (opencode-backup.db etc.) so backups no longer double totals, while
  backup-only sessions are still counted; schema v1 -> v2.

Regression tests cover fork-copied files counted once (including the
Codex total-only variant), duplicated OpenCode databases, and dedupe
stability across cached incremental rescans.

* Fix cross-tool usage double-counting for fork/resume-copied history

- Widen Claude dedupe keys with message-id and uuid fallbacks so forks
  missing requestId still dedupe correctly, and drop Codex's sessionId
  from event keys since fork/resume rewrites session_meta.id while
  copying identical token_count records.
- Track hasDeferredClaims per cached file/database across Claude, Codex,
  and OpenCode scanners so that when an owning file is deleted, only
  files that deferred a claim need reparsing to reclaim those turns
  instead of rescanning the entire corpus.
- Let OpenCode's live opencode.db reclaim sessions from a stale backup
  claim once it reappears, avoiding a frozen stale snapshot.
- Bump schema versions to invalidate caches built with the old,
  narrower ownership keys (#8006, #8013 follow-up).
