Chain test truth pass: Ephapax parser gaps are closed, fix dead paths (#65)

Verified against ephapax 0.1.0 (γ-languages/ephapax): both step-6 parser
probes (plain let and linear let!) now pass — the "2 failing Gossamer
chain tests / parser gaps" v1.0.0 gate recorded since 2026-03 is stale.
Full chain test today: 17/18; the only failure is libgossamer.so not
built in this environment (gossamer FFI links gtk+-3.0 + webkit2gtk-4.1,
whose dev packages need a sudo install — owner action, recorded in
STATE critical-next-actions).

- gossamer-integration-test.sh: default EPHAPAX/LIBGOSSAMER paths moved
  off the dead /var/mnt/eclipse mount to REPOS_ROOT=~/developer/repos
  (env-overridable); stale "known gaps: let!, __ffi(), module, import"
  messaging replaced with the real prerequisite
- CLAUDE.md / ROADMAP / STATE: parser-gap claims corrected; v0.95
  Ephapax parser item checked off; v1.0.0 gate reworded to the
  libgossamer build prerequisite; session history appended
