#53: pre-size chunks rows at INSERT to skip phase-2 page splits 
Real consumer-side bottleneck for cold-pack genesis is the phase-2
chunks-content UPDATE loop: each `UPDATE chunks SET content=? WHERE
chunk_id=?` grows the row from NULL to ~500 bytes, triggering SQLite
page splits, which become ext4 metadata-journal events. With 6M
chunks × 4 parallel writers, those journal events serialize and
dominate consumer wall time (~130 of the 164-min v3-revert run).

Fix: producer dumps a synthetic `_content_size` column in chunks.jsonl
carrying the on-disk byte length of each chunk's content (constant-
time SQLite `length(content)`). Consumer's phase 1 INSERT pre-allocates
the row with `content = bytes(_content_size)` instead of letting it
default to NULL. Phase 2's UPDATE then replaces same-size bytes
in-place — no row growth, no page splits, no per-row journal events.

Implementation:

  arborist/cold_pack_metadata.py
    _dump_generic_table for `chunks`:
      Emit synthetic `_content_size` column = length(content) at the
      end of the columnar header. Underscore prefix avoids collision
      with any future schema column.

    _restore_routed_table:
      Detect `_content_size` in the JSONL header; if present (and
      table == chunks), build INSERT against [chunks_cols] + ['content']
      and substitute a bytes(_content_size) placeholder for the
      content position. Phase 2 UPDATE later replaces those bytes.

Forward compatibility:
  - Old packs (no _content_size): consumer uses today's NULL-content
    INSERT path. No behavior change.
  - New packs: consumer auto-detects, uses pre-sized path.

SPV-wallet trade-off:
  In just-enough mode the consumer pulls only the metadata pack so
  chunks land with the placeholder bytes (NOT NULL anymore). That's
  a SEMANTIC CHANGE for SPV — `chunks.content IS NULL` no longer
  means "JIT-fetch later." Documented in code; if SPV-mode JIT-fetch
  ever ships, it must distinguish placeholder bytes (where every
  byte is 0) from real content.

New test (TestPreSizedChunks.test_chunks_content_pre_sized_after_metadata_restore):
  Hydrate just-enough → chunks rows have non-NULL bytes content of
  correct size. Catches the regression if a future change reverts
  the placeholder logic.

Expected impact: ~50-70% reduction in phase-2 wall time. Real number
lands when the next 3090 bench-max iteration runs against re-packed
bucket. 6 cold-unpack-routed tests pass.
