First public release since v0.1.1. 237 commits of feature work, reliability fixes, and workflow improvements.

Highlights

Env-var expansion inside .codescan/config — $VAR, ${VAR}, ${VAR:-default}, ${VAR-default}, $$ escape; raw-preservation for embedding_api_key so committed configs never bake in secrets.
Watcher syslog logging + codescan log subcommand — watchers now emit lifecycle and error events to the OS log (macOS unified log / Linux journald). Retrieve filtered logs even after the watcher has died. Also exposed as an MCP logs tool.
oMLX / OpenAI-compatible embedding dialect — alongside Ollama. embedding_api=openai, Bearer auth, auto-detection between the two.
Auto-configuration — codescan index probes Ollama, then oMLX, and auto-selects. codescan init writes a working config. codescan setup-model prints instructions for both dialects.
Lexical-only mode — --lexical-only or interactive fallback when no embedding server is reachable.
Watch management — watch list, watch prune for multi-project setups.
MCP edit tools — insert_at, insert_after, replace_lines, replace_symbol, replace_content, create_file, destroy_file.

Connection: close on embedding requests — root cause of batch-mid-index WriteFailed: std.http.Client pooled keep-alive sockets were closed by the server; next reuse surfaced as WriteFailed mid-body. Each embed request now opens a fresh connection.
Retry on transient HTTP errors — HttpConnectionClosing, ConnectionResetByPeer, BrokenPipe, WriteFailed, ReadFailed, ConnectionTimedOut, etc. Three attempts, 100ms / 500ms backoff.
setup-model shows both paths — previously hid the dialect the current config wasn't set to.

POSIX syslog(3) C FFI wrapper.
writeValueFor / setApiKeyLiteral helpers so config writes preserve raw ${VAR} references.
log_cmd module with platform-specific argv builder and in-process filtering.
Extensive test coverage: 494+ tests across 3500+ total including env expansion (24 tests), retry paths, setup-model output, MCP tools, and round-trip config.
