Fork wins kept: the SQLite on-disk cache with --live-only and the per-namespace
ledger, the pi adapter and its per-path namespaces, the OpenCode V2 loader, the
FxHash/Cow hot paths, the table renderer, clear-cache, and the tag-only release
workflow. Upstream's own release and tagpr machinery stays out.

Hand-resolved conflicts:

  rust/adapters/claude/src/lib.rs: upstream's resp_ message-id dedupe (ccusage#1935) lands
    beside the fork's requestless replay and collapse_replays rules.
  rust/adapters/claude/src/README.md: upstream's wording for the msg_/resp_ exception.
  rust/Cargo.toml: zstd 0.14.3, keeping the fork's exact `=` pin style.
  .github/workflows/release.yaml: the fork's tag-only release, without upstream's
    tagpr job or the songmu/tagpr action bump.
  apps/ccusage/package.json, docs/package.json, package.json: keep 20.0.34;
    upstream's 20.0.37 bump is dropped.
  packages/ccusage-*/package.json (6 files): stay deleted; the fork ships no npm
    wrapper packages and the release workflow does not read them.
  rust/adapters/claude/src/daily.rs: stays deleted; the fork's daily path lives in
    lib.rs and shares the dedupe helper the fix changes.

Fixes made while landing this sync, folded in so the merge stands green on its own:

  fix(ci): save the Nix store from the native build composites. The nested
    cache-nix-action read an empty primary-key at post-job and every native
    build failed; upstream's defer-save pattern is the fix.
  fix(rust): keep the agent-recorded cost for deleted sources. The recorded_cost
    ledger column carries it, so storedCost survives a deleted file. The ledger
    schema version stays at 2: the column is not a LedgerEntry field, so the blob
    layout is unchanged and the previously released binary keeps working.
  fix(rust): make the file fingerprint helper private, the one hawk finding. It is
    inherited from the pre-sync master, not introduced here.

Keep 20.0.34 numbering; DO NOT push a v20.0.34 tag from this fork (release.yaml
would publish fork bytes under upstream identity).
