v0.14.0

Theme: the map states what it costs.

Added

• The footer carries the corpus and map token counts.
  · 19,311 LOC · input 215,433 · output 5,999 tokens · state … · budget … —
  input is the estimated token count of the scanned sources, output the
  estimated count of the map itself. The block is always loaded, so what it costs
  and what reading the sources instead would cost now travel with it. output is
  measured on text that contains output, so the render iterates the footer to a
  fixed point; where a token boundary makes two candidates alternate, the larger is
  stated — the map never claims to be cheaper than it is.

render_simple gained an optional source_tokens parameter alongside loc,
precomputable by callers and computed locally when omitted. Freshness and settings
readers are unchanged: LOC stays the footer's first field, which is how the
metadata line is located, and legacy metadata-bearing headers still parse.

The new fields cost nine tokens per map, flat.
