v0.16.0

Theme: a name says only what the reader's position does not.

Added

• --features params. Parameter names were 14–24% of a real map and were
  the one large fact class with no name, because they sat in the always-on
  "identity" remainder alongside the trie and the type headers. They are a fact
  about the code, not the map's structure, so they are selectable now.
  Deselecting keeps arity and drops only the names — place(order,items)
  becomes place(_,_), reusing the placeholder the renderer already emits for
  an argument no extractor could name — and takes about 7% off a map that keeps
  everything else.

Changed

• Grouped landmarks take the declared extension too. {ItemId,OrderId}.java
  now renders {ItemId,OrderId} under a # hologram ·.java header, like every
  other leaf. They had been exempt so that payload naming files could tell a
  reader the bare node above it was a directory — which cost the hoist most of
  its value exactly where it pays best, on the one-public-class-per-file
  languages whose every landmark is grouped. Worth 3.9% of the javamini
  fixture, 0.7% of a Spring corpus and 0.5% (306 tokens) of a 16,000-file Java
  codebase. The reader's rule is now simply that a node with nodes below it is a
  directory; a directory whose files are all grouped landmarks reads as a file,
  measured at about one node in fifty, and never silently — the reconstructed
  path does not exist while the directory does.
• Call targets are named relative to the caller. The description ladder
  picked the shortest name that is unambiguous across the whole project, which
  is the right question to ask once and the wrong one to answer on every line:
  a chain inside a/b/Order.java that read > a/b/Order.java:Order.total
  spent 24 characters restating the node the reader was standing in. A target
  now carries only what the caller's own path, file and owner do not already
  say. Worth 7.9% of a monorepo of near-identical services, 2.4% of a Java
  example corpus, and 1.2% — 699 tokens — of a 16,000-file Java codebase. Two
  targets that would shorten to the same text both keep their project-wide
  names, so one name never stands for two.

Fixed

• Framework-wired code is no longer reported as dead. ×0 means no static
  project reference, and a container's wiring is invisible to static fan-in, so
  Spring stereotypes and @Bean factories, JSR-330 @Named/@Inject,
  @PostConstruct/@PreDestroy lifecycle callbacks, JPA @Entity, and Spring
  AI/MCP @Tool surfaces now join routes, listeners and schedulers as
  entrypoints. On a Spring AI corpus this removed 63 of 113 ×0 markers — a
  @Configuration @EnableWebSecurity class and every @Bean factory had been
  reading as deletable — and made the map 38 tokens smaller in the process.
