Hongming Wang 3a6a7eb495 feat(connect): M1.1 — Backend interface + connect skeleton + mock backend
First step toward `molecule connect <id>` — the out-of-box external-
runtime workspace connector specified in RFC #10.

What's in this PR (foundational, ~300 LOC of code + matching tests):

- `internal/backends.Backend` — the seam every concrete handler
  implements: HandleA2A(ctx, Request) → Response, Close(). Two methods,
  no inheritance, no surprise side effects. Concurrency-safe by
  contract (poll dispatch may parallelise).
- Request/Response/Part/Config types — lossless JSON-RPC mirror so
  backends can re-issue downstream without re-parsing.
- Compile-time registry — `Register("name", factory)` from each
  backend's init(); `Build(name, cfg)` selects at runtime. Panics
  on duplicate registration so drift fails loudly at startup, not
  on first message.
- `mock` backend — single-template echo for CI smoke + tests + demos.
  `--backend-opt reply="<template>"` with `%s` for inbound text.
- `molecule connect <workspace-id>` cobra command — flag surface,
  validation, --dry-run for smoke. Loops (heartbeat, activity poll,
  dispatch) land in M1.2 in internal/connect/.

Coverage:
- Registry: duplicate-name panic, empty-name panic, nil-factory panic,
  Build unknown-name error includes registered list.
- Mock: default template, custom template, text-part concatenation,
  Final=true on terminal response.
- Connect: --backend-opt KEY=VALUE parser (incl. value with =),
  flag validation (missing token, bad mode, bad opt, unknown
  backend), --dry-run happy path.

All tests pass under -race.

Out of scope (subsequent M1 PRs):
- M1.2: heartbeat + activity poll loops in internal/connect/
- M1.3: claude-code backend (wraps molecule-mcp-claude-channel)
- M1.4: GoReleaser tag-triggered release.yml workflow
