docs: ephapax bridge package (#125 + #127) + EchoTypes.jl v0.2.0 surfacing (#132)

[hyperpolymath]

Summary

Resolves three tightly-coupled documentation issues with shared inputs from a coordinated background-agent research dump (`/tmp/ephapax-bridge-proposal.md`):

• docs: surface EchoTypes.jl v0.2.0 as the executable companion in upstream docs #132 — Surface EchoTypes.jl v0.2.0 in 4 files (README + CLAUDE.md + bridge-status table + MAP.adoc Tooling section).
• composition.md: empirical evidence for decoration-violating closure being unsound (ephapax L1→L2 case) #125 — Methodological note in `composition.md` capturing the decoration-violating-closure anti-pattern surfaced by the ephapax four-layer redesign.
• Pillar E / examples.md: ephapax L3 region-exit as canonical example (draft entry + paper paragraph) #127 — Canonical-example entry 11 in `examples.md` (ephapax L3 region exit) + a paper paragraph in `paper.adoc` §"Sample-size on consumer evidence" adding ephapax as the third partial external-corroboration stream.

The Agda companion stub (#126) lands in a separate PR.

Key honest-scope discipline preserved throughout

• R-2026-05-18 narrowings: no "graded comonad" / "model-independence" / "categorical universal property" / "conservativity metatheorem" language re-introduced. Scanned the diff to confirm.
• EchoTypes.jl scope: retracted surface NOT mirrored; F5 funext-qualified clauses (uniqueness up to iso, diagonal lifting) NOT mirrored — Julia has no funext, the claims would be vacuous.
• ephapax L3 paper-paragraph scope: cites L3 ONLY, not implying anything about ephapax's overall posture (L1 has 5 Axiom + 11 Admitted, L2 has 1 Admitted, L4 is skeleton; only L3 is Qed-closed).
• Anti-pattern note: empirical downstream test, NOT a proof of the upstream theorem.

Seam-analyst observations consumed in-PR (not scope-creep)

The background agent caught three drift points while assembling the proposal:

1. `composition.md` is Markdown, not AsciiDoc — issue composition.md: empirical evidence for decoration-violating closure being unsound (ephapax L1→L2 case) #125 asked for AsciiDoc; draft rendered as Markdown to match file (the `.md` / `.adoc` split in `docs/echo-types/` is pre-existing and the policy direction isn't documented; flagging only).
2. Pillar E / examples.md: ephapax L3 region-exit as canonical example (draft entry + paper paragraph) #127's cited line range `EchoResidue.agda:33-73` covers the residue block; the tight theorem range is 52-65. Tight range used in both examples.md and paper.adoc.
3. The MEMORY `feedback_ephapax_affine_proofs_not_done.md` entry was respected — paper paragraph scoped to L3 only, not broadened to "ephapax is fully mechanised".

File-by-file

File	What changed
`README.md`	One-line "Executable companion" callout below synopsis
`CLAUDE.md`	New ecosystem-context bullet for EchoTypes.jl
`docs/bridges/cross-repo-bridge-status.md`	New "EchoTypes.jl executable mirror" row in Tracks table
`docs/echo-types/MAP.adoc` §Tooling	New §"EchoTypes.jl — Executable Julia companion `[REAL]`"
`docs/echo-types/composition.md`	New "Anti-pattern — closing a degrade-map obligation within an endpoint" subsection
`docs/echo-types/examples.md`	New entry 11 "Region exit in a linear type system (ephapax L3)"
`docs/echo-types/paper.adoc`	New paragraph in §"Sample-size on consumer evidence"

Test plan

• All edits are docs — Agda suite unaffected.
• Citation line ranges verified at agent's named theorems.
• No R-2026-05-18 retraction-watch violations introduced.

Closes

• Closes composition.md: empirical evidence for decoration-violating closure being unsound (ephapax L1→L2 case) #125
• Closes Pillar E / examples.md: ephapax L3 region-exit as canonical example (draft entry + paper paragraph) #127
• Closes docs: surface EchoTypes.jl v0.2.0 as the executable companion in upstream docs #132
• Refs echo-types: ephapax↔echo-types bridge package [meta] #128 (umbrella closes when Lane-4 bridge candidate: EchoEphapaxBridge.agda (content bridge to hyperpolymath/ephapax L3) #126 also lands)
• Refs Lane-4 bridge candidate: EchoEphapaxBridge.agda (content bridge to hyperpolymath/ephapax L3) #126 (separate Agda PR — NARROW stub per agent's verdict)
