Docs: composable imports and def syntax alignment¶

Summary¶

Align composable/httpd documentation and package README with workspace import resolution (net.httpd, physics.*) and def procedure syntax.

Agent continuation¶

1. Read docs/ecosystem/composable-by-default.md and docs/language/import-style.md.
2. When editing package READMEs, use import_name from each package li.toml.
3. Next: optional mirror sync for li-httpd if README should match org repo.
4. Blocked: none.

Changed¶

• docs/ecosystem/composable-by-default.md — resolution order, def, net.httpd, physics composable tests.
• docs/language/import-style.md — resolver order, legacy import warnings.
• packages/li-net-httpd/README.md — import net.httpd, Li example syntax.

Not changed¶

• Compiler import resolver (landed in #63).
• httpd implementation (still stubs).

Breaking¶

N/A — documentation only.
