upgrade to zig 0.16.0
IO-as-an-interface refactor across the codebase. The big shifts:
- std.io → std.Io, std.fs → std.Io.Dir/File, std.process.Child → spawn/run.
- Juicy Main: pub fn main(init: std.process.Init) gives gpa, io, arena,
  environ_map up front. main.zig + the build/ scripts use it directly.
- Threading io through everywhere that touches the outside world (HTTP,
  files, stderr, sleep, terminal detection). Functions taking `io` now
  announce side effects at the call site — the smell is the feature.
- date math takes `as_of: Date`, not `today: Date`. Caller resolves
  `--as-of` flag vs wall-clock at the boundary; the function operates
  on whatever date it's given. Every "today" parameter renamed and
  the as_of: ?Date + today: Date pattern collapsed.
- now_s: i64 (or before_s/after_s pairs) for sub-second metadata
  fields like snapshot captured_at, audit cadence, formatAge/fmtTimeAgo.
  Also pure and testable.
- legitimate Timestamp.now callers (cache TTL math, FetchResult
  timestamps, rate limiter, per-frame TUI "now" captures) gain
  `// wall-clock required: ...` comments justifying the read.

Test discovery: replaced the local refAllDeclsRecursive with bare
std.testing.refAllDecls(@This()). Sema-pulling main.zig's top-level
decls reaches every test file transitively through the import graph;
no explicit _ = @import(...) lines needed.

Cleanup along the way:
- Dropped DataService.allocator()/io() accessor methods; renamed the
  fields to drop the base_ prefix. Callers use self.allocator and
  self.io directly.
- Dropped now-vestigial io parameters from buildSnapshot,
  analyzePortfolio, compareSchwabSummary, compareAccounts,
  buildPortfolioData, divs.display, quote.display, parsePortfolioOpts,
  aggregateLiveStocks, renderEarningsLines, capitalGainsIndicator,
  aggregateDripLots, printLotRow, portfolio.display, printSnapNote.
- Dropped the unused contributions.computeAttribution date-form
  wrapper (only computeAttributionSpec is called).
- formatAge/fmtTimeAgo take (before_s, after_s) instead of io and
  reading the clock internally.
- parseProjectionsConfig uses an internal stack-buffer
  FixedBufferAllocator instead of an allocator parameter.
- ThreadSafeAllocator wrappers in cache concurrency tests dropped
  (0.16's DebugAllocator is thread-safe by default).
- analyzePortfolio bug surfaced by the rename: snapshot.zig was
  passing wall-clock today instead of as_of, mis-valuing cash/CDs
  for historical backfills.

83 new unit tests added due to removal of IO, bringing coverage from 58%
-> 64%
