v0.1.52

Patch Changes

• add2f36: debug MCP: a --target=local start can now hot-switch into relay (and back) without restarting the daemon. The DualConnectionRouter is generalized to be direction-neutral — an eager family booted at startup plus a lazily-booted opposite-kind family — so both entry points (runDebugServer relay-eager and runLocalDebugServer local-eager) share the same bidirectional start_debug swap. Previously only the default relay-target start carried the dual router; a local start pinned a single-connection router and rejected cross-family switches as "restart required", breaking the env 1 → env 3 fidelity-ladder flow at that entry point.
• 4141b3b: debug MCP: fix a per-call env snapshot regression and a LIVE side-effect guard race introduced with start_debug(mode) dual-connection routing. The CallTool handler now snapshots the derived environment (env/envReason) once at entry and reuses it at every output site, so a concurrent start_debug swap mid-await can no longer stamp the wrong env into a response envelope. The evaluate / call_sdk LIVE guard now evaluates connection.kind === 'relay' && getLiveIntent() with a snapshot conn.kind plus a fresh liveIntent read at the side-effect boundary — closing a race where a concurrent start_debug('relay-live') armed liveIntent while a relay-dev call was parked on an await, previously letting a LIVE side-effect run without confirm: true.
• c3cfd3d: debug MCP: start_debug(mode) single entry to switch environments (env 1/3/4) in-place — one daemon now holds both a local and a relay CDP connection at once and flips the active pointer with no Claude Code restart or MCP re-handshake (warm attach survives the switch). Replaces the URL-sniffing getEnvironment() precedence chain with a derived model: mock vs relay-* comes free from connection.kind, and relay-dev vs relay-live is a single operator-supplied liveIntent bit armed only by start_debug({ mode: 'relay-live' }). The LIVE side-effect guard collapses to connection.kind === 'relay' && liveIntent, so switching back to a local target auto-disarms it. --mode/--target/MCP_ENV (incl. MCP_ENV=relay-live seeding LIVE intent) remain as back-compat aliases.
