* feat: add JSON language server support via vscode-json-languageserver (fixes#1391)
Add support for JSON files using the `vscode-json-languageserver` npm package
from Microsoft. This provides document symbol navigation and hover information
for JSON files.
The implementation follows the existing YAML language server pattern:
- Auto-installs `vscode-json-languageserver` via npm on first use
- Requires Node.js and npm
- Marked as experimental (must be explicitly specified)

* Add "Quick Demo" section with new videos
* Remove old section "Serena in Action"
* Update section "How Serena Works", removing redundant part explaining backends (this is what the next section handles)
* feat: add mSL (mIRC Scripting Language) support
Add language server support for mIRC Scripting Language (.mrc files).
mSL is used in mIRC and AdiIRC IRC clients for scripting bots, games,
and automation.
The implementation uses a custom Python-based LSP server (pygls) that
parses aliases, events, menus, dialogs, and CTCP handlers. Dependencies
(pygls, lsprotocol) are installed in an isolated venv on first use.
Includes test repo, integration tests, and documentation updates.
* style: apply ruff formatting to msl_language_server.py
* fix: remove INITIALIZE handler that crashes pygls 2.x
pygls 2.x handles the initialize request internally. Overriding
it via @server.feature(lsp.INITIALIZE) causes the LSP subprocess
to crash. Removing the handler lets pygls auto-advertise capabilities
based on registered features (document_symbol, workspace_symbol).
* fix: update embedded LSP script for pygls 2.x
pygls 2.x moved LanguageServer from pygls.server to pygls.lsp.server.
Update import and bump requirement from pygls>=1.3.0 to pygls>=2.0.0.
* refactor: ship mSL LSP as package module, not runtime disk write
Per maintainer feedback: the mSL LSP is a Python script, so it should
ship as a module inside the package rather than being written to disk
at runtime.
Changes:
- Extract embedded LSP script to msl_lsp_server.py (proper module)
- Simplify MslLanguageServer: remove venv creation, disk writes,
_create_msl_lsp_files(). DependencyProvider now just returns
sys.executable and launches the sibling module directly.
- Add pygls>=2.0.0 and lsprotocol>=2023.0.0 to pyproject.toml deps
* fix: regenerate uv.lock after upstream v1.1.0 merge
* feat(msl): add references, definitions, and expand test coverage
- Add textDocument/references handler for cross-file alias reference finding
- Add textDocument/definition handler for go-to-definition support
- Handle $ prefix on cursor position for mSL identifiers
- Fix pre-existing mypy error in agent.py (dict[str, object] -> dict[str, str | int])
- Add MSL to _LANGUAGE_PYTEST_MARKERS in conftest.py
- Add MSL parametrized cases to test_find_symbol_stable and test_find_symbol_references_stable
- Expand test repo with cross-file reference examples (main.mrc <-> utils.mrc)
- Add within-file and cross-file reference tests to test_msl_basic.py
- Update docs and CHANGELOG to reflect expanded capabilities

* fix(msl): add hover handler, fix cross-file references via filesystem scan
Root causes of 4 CI test failures:
- textDocument/hover was not implemented (test_find_symbol_stable needs it)
- references/workspace_symbol/definition only searched opened documents,
missing files not explicitly opened by the client
- pygls.uris.to_fs_path returns lowercase drive letters on Windows,
causing URI mismatch with the framework's repository path comparison
Fixes:
- Add textDocument/hover handler returning definition snippets in Markdown
- Add _get_all_mrc_files() to scan workspace filesystem for all .mrc files
- Read workspace roots from server.workspace (pygls 2.x API) instead of
broken monkey-patching of server.lsp
- Use pathlib.Path.resolve() to normalize drive letter casing on Windows
- Simplify __main__ to just server.start_io()
All 12 tests pass locally (10 solidlsp + 2 serena_agent integration).

Improve README:
* Move LS deps back to prerequisites
* Remove incorrect config path (redundant anyway, because user sees it upon init)
* Some wording changes
References and definition not working yet. Since ansible resolves same files as yaml LS, we will need to add disambiguation later.
Work in progress, improvements on the language server itself are being worked on, ansible support in Serena will be extended accordingly in the future.
Integrates the Nomic Foundation @nomicfoundation/solidity-language-server
as a new Language.SOLIDITY backend (experimental). Supports .sol files with
go-to-definition, find references, document symbols, hover, and diagnostics.
The server is automatically installed via npm on first use.
