distribute/proposals.py: Scope-aware targeting (FR-X2, empty axis = any), render
distributable (approved+distribution_ready) patterns into a proposals/ tree
mirroring target paths — proposed not applied (FR-X3, HITL), idempotent on re-run.
ActiveRegistry (FR-X4) records which pattern+version is proposed in which
(repo,flavor). 6 new tests; suite 123/123.

Thin per-flavor distributors over the shared base: Claude (CLAUDE.md, optional
skill-stub mode), Codex (AGENTS.md), Grok (.grok/instructions.md). registry maps
flavor->distributor — adding a flavor is one entry + one module. Same agnostic
body renders to distinct per-flavor targets (FR-A3). 7 new tests; suite 117/117.

distribute/base.py: Artifact dataclass + Distributor protocol + idempotent
BEGIN/END snippet markers (upsert_block replaces a pattern's block in place so
re-distribution doesn't duplicate) + agnostic markdown body rendering from
SolutionPattern fields. BaseDistributor honours per-flavor body/target hints.
8 new tests; suite 110/110.
