CHORE - Fix command syntax in documentation

[molson504x]

This pull request standardizes command references throughout the documentation by converting all occurrences of slash-separated commands (e.g., /speckit.implement) to their hyphenated forms (e.g., /speckit-implement). This improves consistency and aligns the docs with the current command naming conventions. The changes affect both the conceptual documentation and community extension/preset listings.

The most important changes are:

Documentation consistency:

• Updated all command references in docs/concepts/complex-features.md and docs/concepts/spec-of-specs.md from the old slash-dot format (e.g., /speckit.implement) to the new slash-hyphen format (e.g., /speckit-implement). [1] [2] [3] [4] [5] [6]

Community extension and preset listings:

• Standardized command references in docs/community/extensions.md and docs/community/presets.md to use hyphenated forms, ensuring extension descriptions and preset summaries are consistent with the new command syntax. [1] [2] [3] [4] [5] [6] [7] [8]

These changes enhance clarity for users and reduce confusion by unifying command syntax across all documentation.

🟡 Changes recommended

Generic documentation now presents Copilot-specific syntax despite supported integrations using several invocation formats, and the SDD reference contradicts its own notation guidance.

Please address Copilot feedback where applicable. Note that I am fine with the Copilot skill syntax as the command shown. No need to repeat anywhere that the syntax might be different for different agents. Except for the installation page as there we have the one time someone could be picking another agent

🔵 Needs a closer look

The Agentic SDD page still claims it uses dotted notation despite its converted examples.
