Split the REPL strategy into a separate @ocap/kernel-agents-repl package
to remove tree-sitter native addon dependencies from @ocap/kernel-agents.
This is one step toward enabling @ocap/kernel-agents to be bundled into
vats using @endo/bundle-source, which cannot bundle native addons. The
REPL strategy requires tree-sitter for JavaScript parsing, while the JSON
strategy does not. Users who need REPL agents can now import from the
dedicated package.
Changes:
- Created @ocap/kernel-agents-repl package with REPL strategy code
- Moved all REPL-related files to new package
- Removed tree-sitter and tree-sitter-javascript from kernel-agents deps
- Removed /repl export from kernel-agents package.json
- Added exports to kernel-agents for shared code (agent, types, utils, capabilities)
- Updated imports in kernel-agents tests to use @ocap/kernel-agents-repl
Migration:
- Before: import { makeReplAgent } from '@ocap/kernel-agents/repl'
- After: import { makeReplAgent } from '@ocap/kernel-agents-repl'
WIP Notes:
The test suite of kernel-agents depends on the kernel-agents-repl package,
but this dependency inversion is not realized in the dependency graph.
Following a PR to add a kernel-test-local package, the tests should be
moved there, resolving the cycle.

Separates into its own package the portion of the kernel-agents package that depends upon native bindings. The new package is called kernel-agents-repl.
