v2.1.1

[v2.1.1]

• Fix antidote.zsh exiting the shell when sourced from compiled .zwc bytecode (#270). Zsh reports the eval context as filecode rather than file in that case, so the sourced check fell through to the CLI branch.
• Fix antidote bundle exiting 1 for bundle files containing only kind:clone entries, and make it exit non-zero when a clone or a parallel script generation job fails. Previously those failures printed to stderr but still exited 0.
• Fix antidote load returning 0 when the static file was missing or could not be sourced.
• Fix antidote update printing "self-update complete" after a failed self-update. It now reports the error and returns 1.
• Fix antidote purge commenting out unrelated bundles in the plugins file when one bundle name was a prefix of another (eg: purging foo/bar also matched foo/barbaz). Names now match literally, whole word only.
• Fix antidote install silently writing :value garbage to the plugins file for unknown short flags. It now fails with an error.
• Fix antidote snapshot restore reporting success when restores failed, and fix pinned restores always failing under ephemeral pins.
• Fix antidote list --jsonl producing invalid JSON when values contained quotes, backslashes, or control characters.
• Fix antidote-dispatch and antidote-help leaking private usage helper functions into the user's shell.
• Fix the non-Zsh guard misreporting the shell name, and tolerate a ps without -p (busybox).
• Speed up antidote update by only probing for bat when the snapshot picker actually runs.
• Ehance completions: install gains arg specs, a --pin value, and bundle positionals; path completes installed bundles; help completes topics; load and snapshot complete files.
• Remove unused git config isolation from update that would have broken credential helpers and insteadOf rewrites had it ever taken effect.
• Add an ARCHITECTURE.md guide covering file layout, the parent/subprocess boundary, and the bundle pipeline.
• Internal: rename globals so ANTIDOTE_* means externally managed only, decompose oversized functions, and make antidote.zsh clean under warn_nested_var. No behavior changes.
• Internal: migrate the test suite from clitest markdown files to bats (tests/bats), with network tests split out under just test-real.
