Keep the executable run spec out of reach of event redaction
Two root-cause fixes for the sandbox failure where an inline Dockerfile
came back from the store as `ARG REDACTED` and the Daytona snapshot
build died on the unset variable.

Entropy redaction measures values, not assignment pairs. The detector
matched `NAME=value` as one token, so an uppercase name merged its
charset into a pure-hex value (which alone can never exceed 4.0 bits)
and pushed the pair over the 4.5-bit threshold — then replaced the
whole pair, destroying the name. `find_entropy_regions` now strips an
identifier-shaped `NAME=` prefix before measuring and redacts only the
value, matching the gitleaks layer's `key=REDACTED` shape.

Execution no longer reads redacted content. Every stored event passes
through the redaction sink, and `load_from_store` rehydrated the
worker's RunSpec from the projection folded from those events — so a
redactor false positive silently rewrote the spec the sandbox builds
from (and changed its snapshot identity). The creation path now writes
the exact spec bytes to the content-addressed blob store and records
`spec_blob` on run.created; `load_from_store` loads the spec from the
blob, keeping the event stream authoritative for run identity,
provenance, and event-recorded blob ids. Retry and fork carry the
source run's `spec_blob` forward, so derived runs stop inheriting the
redacted copy. Runs created before the blob existed fall back to the
folded spec.

The projection and every API surface keep serving the redacted fold;
blobs were already stored unredacted (the workflow bundle carries the
same bytes), so this adds no new exposure at rest.
