Removed the direnv-allow preflight so an .envrc the user never allowed is
skipped silently (debug log) and never executed; only already-allowed files
export. Updated the setting description, changelog, and rewrote the tests to
allow explicitly per content change.
Extract applyDirenvPreflight() so the ACP client terminal and PTY backends
get the same direnv/devenv overlay as executeBash (previously only the
one-shot path did). The helper is a pure (command, env) transform — merge
direnv's set under the caller's overlay, prepend a regex-gated unset -v for
removed vars — so interactive backends keep their own env shape (live TERM)
while executeBash still layers its non-interactive defaults on top. The three
dispatch branches are mutually exclusive, so no command is preflighted twice.
Also drop the content-hash export cache in loadDirenvEnv: always run
direnv export json and let direnv's own watch/mtime invalidation decide
freshness, so a changed watched file re-exports even when .envrc is unchanged.

Drain stdout and stderr concurrently so a cold .envrc/devenv load can't fill the stderr pipe and block until the timeout cap. Thread the caller's abort signal and per-call timeout into the direnv preflight (AbortSignal.any + min timeout) so an aborted or short-timeout bash call returns promptly. Return the full direnv export diff and honor variable *removals*: the per-command env overlay can only add/override, so prepend a shell-level 'unset -v' for direnv's unset list, gated by a POSIX-identifier regex and skipped when the caller re-supplied the var. Tests: skip the real-direnv cases when direnv is absent, and isolate HOME/XDG so 'direnv allow' never writes into the developer's global store; add unset coverage.
The bash tool's persistent shell didn't carry a repo's direnv/devenv
environment, so devenv-provided tools (moon, project-pinned biome/bun,
toolchains) were off PATH and .envrc-set vars (e.g. GIT_DIR for a jj
secondary workspace) were missing. Resolve the nearest .envrc from the
run cwd, load its env via direnv export json, and merge it under the
caller's per-call env. Gated by bash.direnv (default auto, auto-allows).
