fix(financial-analysis): repair invalid .mcp.json; extend check.py to lint MCP and hooks configs

What

• Fix: plugins/vertical-plugins/financial-analysis/.mcp.json was invalid JSON. A missing comma after the egnyte entry and a missing closing brace on box meant the file failed to parse, so none of the plugin's 12 MCP connectors (Daloopa, Morningstar, S&P Global, FactSet, Moody's, MT Newswires, Aiera, LSEG, PitchBook, Chronograph, Egnyte, Box) could load. Since financial-analysis is the recommended first install, this affects every fresh setup that follows the README.
• Prevention: scripts/check.py covered plugin.json, marketplace.json, and steering-examples.json but not .mcp.json or hooks.json, which is how the broken file shipped while check.py reported OK, 80 files, 0 issues. Added both globs to the existing JSON parse pass (section 2), matching the current style. File count goes 80 to 90.
• Version: bumped financial-analysis 0.1.1 to 0.1.2 per the repo's version-bump rule so already-installed users receive the fix.

Verification

# before fix, with new check
FAIL — 1 issue(s) across 90 file(s):
  ✗ JSON parse: plugins/vertical-plugins/financial-analysis/.mcp.json:
    Expecting ',' delimiter: line 47 column 5 (char 1100)

# after fix
OK — 90 file(s) checked, 0 issues.

Also confirmed json.load succeeds on the repaired file and returns all 12 servers.

Notes

• No behavior change to check.py beyond the two added globs.
• Unrelated but observed while auditing: CLAUDE.md lists mcp-categories.json as a key file, and that file does not exist in the repo. Happy to address in a follow-up if you confirm whether it should be added or the doc line removed.

Found this while auditing the repo for a client enablement program. Happy to follow up on the mcp-categories.json doc drift noted in the description too.
