Markdown hawkeye integration notes

Hawkeye excludes *.md by default and has no built-in header type for Markdown, so two companion config files were added:

• licenserc-md.toml — hawkeye config for Markdown, with a !**/*.md negation rule to override the default exclusion and a MARKDOWN_STYLE mapping for the .md extension
• licenserc-md-header.toml — defines MARKDOWN_STYLE as an HTML comment block (<!-- ... -->) without extra blank lines, matching our existing header format

The CI license-headers job now runs hawkeye check --config licenserc-md.toml for Markdown.

Request changes: fold Markdown into the single hawkeye config/check, and standardize the header wording repo-wide

Thanks for extending header enforcement to the docs — the goal is right. I'd like to land it as one config driving the existing single hawkeye check, rather than a second config plus a second CI step. Everything below is verified against hawkeye 6.5.1 (the version CI pins).

1. One config, one check

hawkeye applies a single inlineHeader across all file types and picks the comment style per extension, so source and Markdown can share one config and one hawkeye check. Fold the Markdown bits into licenserc.toml:

inlineHeader = """
Copyright © Advanced Micro Devices, Inc., or its affiliates.

SPDX-License-Identifier: MIT
"""

additionalHeaders = ["licenserc-md-header.toml"]

includes = [
  "**/*.rs",
  "**/*.py",
  "**/*.sh",
  "**/*.md",
]

excludes = [
  "!**/*.md",
  "target/**",
  ".claude/**",
  ".tmp-*/**",
  "third_party/**",
]

[mapping.MARKDOWN_STYLE]
extensions = ["md"]

Then:

• delete licenserc-md.toml;
• keep licenserc-md-header.toml (the custom <!-- --> style definition) — hawkeye rejects an inline [headerStyles] table (unknown field headerStyles), so the companion file is required and is pulled in via additionalHeaders;
• drop the extra Check license headers (Markdown) CI step; the existing hawkeye check now covers everything.

The !**/*.md negation is still required — without it, **/*.md in includes is swallowed by hawkeye's default excludes and nothing gets checked.

2. Standardize the wording repo-wide

A single config has exactly one inlineHeader, and the Markdown wording here (Copyright © …, or its affiliates.) differs from the existing source wording (Copyright Advanced Micro Devices, Inc.). The decision is to adopt the © form everywhere, so re-apply it to the existing source headers:

hawkeye format

This rewrites the .rs/.py/.sh headers in place to match (verified: it replaces the old wording, and hawkeye check then passes for both source and Markdown). It does touch the existing source files — that is intended, so there is one canonical wording across the repo.

3. Heads-up: the directory excludes do not apply to Markdown

!**/*.md is a force-include and overrides the later target/**, .claude/**, .tmp-*/**, third_party/** excludes for .md files (confirmed in either order; even a more specific third_party/**/*.md cannot win against it). It is harmless today — there are no tracked .md files under those paths, and hawkeye's git integration skips untracked dirs — but the day a vendored third_party/*.md lands, CI would demand a copyright header on third-party content. Worth a comment in the config noting the limitation.

Minor

• "third_party/**" lost its indentation in the licenserc-md.toml excludes list.
• the companion-file comment says "without extra blank lines" but sets allowBlankLines = true.

[juhovainio]

All addressed — thanks for the thorough review.

• One config, one check: merged licenserc-md.toml into licenserc.toml, deleted the separate file, dropped the second CI step.
• Standardized wording: ran hawkeye format to rewrite all .rs/.py/.sh headers to the © form. Also picked up 9 new files added by the IA redesign (#62) that landed in main while this PR was in flight.
• Negation limitation comment: added to licenserc.toml.
• allowBlankLines comment: fixed in licenserc-md-header.toml.
• Indentation: fixed.
• Conflict: rebased onto main; the one conflict was tabs/overview.rs (deleted in #62, header-modified here) — resolved by accepting the deletion.

This is great. Thanks, Juho!
