Allow extends: to accept a list of bottle names in addition to a plain
string. Parents are resolved independently and folded left-to-right
into a single combined parent before the child is merged on top, so
orthogonal concerns (base env, networking, agent provider) can live in
separate bottles without forcing a linear chain.
Merge rules for the parent fold: env dict-merge with later winning on
collision; git-gate.user per-field overlay; git-gate.repos union by
name with later winning per-field on same name; egress.routes
concatenated; all scalar fields (supervise, agent_provider, egress.log)
use last-wins. The existing child-wins-over-all-parents rule is
unchanged. Cycle detection, diamond deduplication, and missing/invalid
parent errors all work across multi-parent graphs.

Manifest.resolve() now returns an empty-dict manifest with only directory
paths recorded (home_md, cwd_md). No content is read from any .md file
until load_for_agent() is called for a specific agent at preflight.
- Manifest.from_md_dirs: scan-only, no frontmatter parsing
- Manifest.load_for_agent: parses the selected agent file and its bottle
chain; works on eager (from_json_obj) manifests too by returning self
- Manifest.all_agent_names: scans filenames in lazy mode
- backend._validate: calls load_for_agent and propagates upgraded spec
- cli/info.py, cli/list.py, cli/start.py: use load_for_agent / all_agent_names
- manifest_extends.py: reverted to original (no partial-resolve helpers)
- manifest_loader.py: only scan_agent_names + load_bottle_chain_from_dir
- Tests updated to call load_for_agent before accessing agents/bottles;
test_md_agent_repos_deferred renamed to test_md_agent_repos_fails_at_preflight
Broken bottle/agent files no longer block the agent selector or prevent
unrelated agents from loading. Per-file parse errors are collected in
`Manifest.broken_agents`; the CLI selector includes them via
`all_agent_names`, and the error surfaces only when the specific agent
is selected and launch is attempted (in `require_agent`/`bottle_for`).
