feat(branding): match approved rose-mauve ASCII brain and SemantIQ title

[kaveh8866]

1. Contribution classification

• Fast contribution path — isolated presentation / optional CLI branding change.
• Core change path
• Base: protected main 979cf511e2fc57811fb3cef3766be1653a2e45f5 (includes merged PR feat(branding): compact colored SemantIQ brain logo in README and CLI #186).
• Scope: approved SemantIQ ASCII branding treatment only; no model, evaluator, provider, runtime or scientific qualification changes.

2. Approved design implementation

This PR implements the project owner's approved README / CLI preview, using its warm blush / dusty rose / mauve / lavender / desaturated blue-gray colors rather than the previous cyan/teal/navy treatment.

Both original ASCII forms are preserved:

• Brain: pre-existing 27-line compact glyph asset packages/python/src/semantiq/assets/semantiq-logo.txt is byte-identical to protected main and has not been redesigned.
• Title: restore the original owner-supplied eight-line SemantIQ █/░ block-character wordmark (not a font replacement) in packages/python/src/semantiq/assets/semantiq-wordmark.txt.
• README banner contains the literal lines of both assets rendered with a monospaced SVG text layer; fixed-column alignment has been retained.
• CLI assembles brain + one blank line + exact ASCII title; --color=auto|always|never behavior is unchanged except for the new approved RGB palette.
• Plain-output and ANSI-stripped-output roundtrip to the exact combined source glyphs.

SVG banner remains compact within README and uses rose/mauve warm atmospheric background. Docs/branding/COLOR_TOKENS.md records reusable website-theme tokens but does not modify web UI.

3. Files changed

1. Docs/CLI_USAGE.md — both ASCII shapes and 90-column display guidance.
2. Docs/branding/COLOR_TOKENS.md — approved palette and provenance.
3. Docs/branding/semantiq-brain-compact.svg — exact source-character SVG artwork and warm reference palette.
4. README.md — updated accessible alt and design/CLI notes.
5. packages/python/src/semantiq/assets/semantiq-wordmark.txt — original ASCII title.
6. packages/python/src/semantiq/cli.py — title support / RGB ANSI palette.
7. packages/python/tests/test_cli.py — plain/colored exact character regression.
8. scripts/semantiq-logo.mjs — parity for workspace terminal.
9. tests/unit/semantiq-logo.test.ts — source glyph invariance, SVG and ANSI test.

4. Evidence and known boundaries

Static connector preflight: passed on exact protected-main SHA. Nine expected changed files; no other file touched. Brain asset unchanged; title is eight rows; both sets of glyph lines are present verbatim in the SVG; main has not moved.

Automated GitHub CI: pending at PR creation. Do not claim tests pass until checks complete.
Human CODEOWNER review: required, not self-approved.

SVG is an implementation of the approved visual reference using browser font rendering. Its on-screen rasterization can differ by platform; it is not a pixel-for-pixel reproduction of the illustrative preview image. The CLI cannot color backgrounds or shrink terminal font sizes; it uses ANSI RGB foregrounds.

5. Merge and scientific guardrails

• This is a Draft PR for independent review and CI.
• Do not auto-merge or bypass CODEOWNER, branch protection or stale review policies.
• PR feat(benchmark): add controlled semantic core qualification #166 remains Draft/unmerged; PR refactor(benchmark): expose existing offline metric aggregation #183 remains separate.
• Semantic Core remains NOT_QUALIFIED; public maturity BM2 / UNVALIDATED_PROXY / NOT_PROMOTED, scientific authority NONE.
• No scientific/evidence mutation, benchmark promotion, release or tag.

APPROVE — SemantIQ ASCII Branding & Color Palette Update

Reviewed PR #187 at commit 3517ef8488d9930bd00731e77175be11f8d746e8.

Review findings:

• The original eight-line SemantIQ ASCII wordmark has been restored.
• The existing 27-line compact brain artwork remains unchanged.
• The README SVG presents both original ASCII forms using the approved blush, rose, mauve, lavender, and muted blue-gray palette.
• Python and Node CLI commands display the same ASCII artwork.
• ANSI color support preserves --color=auto|always|never, including plain-text fallback.
• Branding regression tests verify glyph preservation and color-output consistency.
• All 12 GitHub Actions jobs passed on the exact reviewed commit.
• No changes to benchmark evaluation, scientific evidence, qualification status, or provider behavior were introduced.

Review decision: APPROVE.

No blocking issues were identified in the reviewed changes.

Merge recommendation: SQUASH AND MERGE, subject to all required independent CODEOWNER approvals and branch-protection checks.

Suggested squash commit:

feat(branding): align SemantIQ ASCII logo with approved brand palette

This approval applies exclusively to branding and CLI presentation. It does not authorize scientific qualification, benchmark maturity promotion, or release.
