Alex Dunmow ad6d87bf06 feat(ninja): plugin build/verify → .bnp packer + ABI riders (WO-WZ-009)
`ninja plugin build` compiles a plugin to reactor-mode wasip1 wasm (Go >= 1.24
enforced), extracts manifest.pb by driving one HOOK_DESCRIBE over wazero with
failing host stubs, and packs a tar.zst .bnp (plugin.wasm, plugin.mod,
manifest.pb + migrations/schemas/assets/web-dist when present) with a summary
table. A describe-time capability call (e.g. db.* from Register) fails with an
actionable error naming the offending method. `ninja plugin verify` re-runs the
CMS reader's layout/name/abi/path-safety/size checks standalone (deliberate
duplication of cms backend/plugin/bnp/reader.go; kept in lockstep by WO-WZ-010).

ABI riders (additive; buf breaking clean):
- ABI_ERROR_CODE_TX_EXPIRED enum value + bnwasm guest mapping to a new
  bnwasm.ErrTxExpired sentinel (retryable tx expiry, distinct from real faults);
  the cms dbexec side adopts the emit separately.
- PluginManifest.data_dir bool + a first-class `data_dir` key on the plugin.mod
  parser (so writeMod's struct round-trip can't drop it); `plugin build` stamps
  it from plugin.mod into the manifest.

Docs: wasm-abi.md gains a Building & packing section, the error-code table row,
the manifest data_dir mapping, and the plugin.mod reference. Tests: CLI e2e
builds the WZ-002 fixture → verify + manifest block keys; a capfixture proves
the actionable describe-time error; verify rejects each malformed class;
bnwasm TX_EXPIRED classification.
