All epoch timestamp fields (timestamp, last_replayed, created_at on
nodes; timestamp on relations) are now i64. Previously a mix of f64
and i64 which caused type seams and required unnecessary casts.
- Kill now_epoch() -> f64 and now_epoch_i64(), replace with single
now_epoch() -> i64
- All formatting functions take i64
- new_node() sets created_at automatically
- journal-ts-migrate handles all nodes, with valid_range check to
detect garbage from f64->i64 bit reinterpretation
- capnp schema: Float64 -> Int64 for all timestamp fields
- date_to_epoch, iso_week_info, weeks_in_month: replaced unsafe libc
(mktime, strftime, localtime_r) with chrono NaiveDate and IsoWeek
- epoch_to_local: replaced unsafe libc localtime_r with chrono Local
- New util.rs with memory_subdir() helper: ensures subdir exists and
propagates errors instead of silently ignoring them
- Removed three duplicate agent_results_dir() definitions across
digest.rs, consolidate.rs, enrich.rs
- load_digest_files, parse_all_digest_links, find_consolidation_reports
now return Result to properly propagate directory creation errors

mod.rs was 937 lines with all Store methods in one block.
Split into three files by responsibility:
- persist.rs (318 lines): load, save, replay, append, snapshot
— all disk IO and cache management
- ops.rs (300 lines): upsert, delete, modify, mark_used/wrong,
decay, fix_categories, cap_degree — all mutations
- mod.rs (356 lines): re-exports, key resolution, ingestion,
rendering, search — read-only operations
No behavioral changes; cargo check + full smoke test pass.
