`get_change_impact` renamed to `blast_radius` (same handler and parameters). Release adds 8 Inspector improvements, 25-language concurrency analysis, and enhanced `blast_radius` with dead-code and coverage-gap detection.

Why it matters: Update code calling `get_change_impact` to use `blast_radius` before upgrading. New scope and filter options enable dead-code and coverage-gap queries across 25-language concurrency analysis.

Full changelog

Breaking

get_change_impact renamed to blast_radius. Same handler, same parameters, new name.

Added

Inspector evolution (8 improvements to /lsp-inspect):

Batch mode (--top N): directory-level inspection with ranked output
Comparison mode (--diff): branch-only issue detection
Fix suggestions: exact fix text for every finding
Confidence tiers: verified/suspected/advisory
Blast-radius severity calibration using caller counts
Results persisted to .agent-lsp/last-inspection.json
MCP resource inspect://last for programmatic access
Inspector now has 12 check types (was 8)

Concurrency analysis (language-agnostic, 25 languages):

4 new inspector checks: unrecovered_concurrent_entry, unchecked_shared_state, channel_never_closed, shared_field_without_sync
blast_radius: sync_guarded metadata on mutex-protected types
find_callers: cross_concurrent flag traces through goroutine/thread boundaries
/lsp-concurrency-audit skill (24th skill): field-level safety report

Agent DX improvements:

explore_symbol: type info + source + callers + refs in one call
safe_apply_edit: preview + auto-apply when net_delta == 0
Auto-diagnostics: errors_after/warnings_after in symbol edit responses
Indexed indicator: indexed: true/false in blast_radius/find_references/find_symbol
Proactive diagnostic regression notifications via DiagChangeTracker
Intent aliases: callers, explore, safe_edit

Other:

blast_radius: scope: "all" for unexported dead code detection
blast_radius: filter: "untested" for coverage gap queries

Summary
