v0.10.0

Added

• init-source --marketplace scaffolds a .claude-plugin/marketplace.json
  (via a new scaffold module); --flat-skills sets flat-skills = true in
  mind.toml and, combined with --marketplace, populates the plugin skills
  array from flat-skill discovery. Plugin-name precedence is --namespace >
  [source].prefix > directory name (INIT-10, INIT-11, INIT-12).
• Cross-source collision detection at meld for skills, rules, and tools: when
  a melded source would install an item that collides with an existing one, the
  non-interactive path errors with SkillCollision and suggests --namespace <repo-name>, and an interactive TTY prompts for a prefix (NS-43, NS-44,
  NS-45).
• config lobes add/detect backfills already-installed items into a
  newly-added lobe: --yes backfills automatically, an interactive TTY prompts,
  and a non-interactive run prints a note pointing at introspect --fix
  (HARN-7).
• introspect --fix repairs missing lobe coverage, creating links for items not
  yet linked into a configured lobe and updating the manifest (HARN-8).

Changed

• The gemini and antigravity harness lobes are unified to ~/.gemini/config,
  the skill directory both Gemini CLI and Antigravity read. The gemini preset
  now targets .gemini/config with kinds = [skill] (was .gemini with
  [skill, agent]); the redundant antigravity and antigravity-cli presets
  are removed (HARN-4, HARN-5).
• The [discover].sources entry key as is renamed namespace (as remains a
  backwards-compatible parse alias). dump emits namespace, review advises
  migrating, and recall --sources displays namespace:<prefix> instead of
  as:<prefix> (DSC-78).
• A [discover].sources entry whose clone fails for a non-auth reason (network
  error, not-found) now warns and skips rather than failing the whole meld; the
  primary source and successfully-cloned nested sources stay registered, and the
  skipped entry is recorded with reason="clone_failure". The same skip applies
  during sync re-walk. The one hard-fail case is a pure curator (no items of
  its own) whose nested sources all fail, which errors with
  CuratorAllNestedFailed (DSC-79, DSC-80).

Fixed

• Adding the first explicit lobe to an empty lobes config via config lobes add/detect now prepends claude_home to the saved list. Previously the
  implicit ~/.claude default was silently dropped from agent_homes(), so new
  installs stopped reaching Claude and introspect --fix could not see the
  Claude home as a coverage target (HARN-9).
• In-repo marketplace entries with source: "./" no longer drop all but the
  first plugin; each plugin is scanned as its own catalog root. Plugin repos
  used as nested [discover].sources entries inherit the plugin name as their
  default namespace, and marketplace-as-nested-source preserves per-plugin
  namespacing (MKT-12, MKT-13, MKT-14).
